Foreword

When 150 heads of government signed the Convention on Biological Diversity at Rio deJaneiro in June 1992, they were responding to a world-wide conviction that we must allcontribute to an initiative to limit the loss of animal and plant species. Gilbert White, writing atthe end of the eighteenth century, had no concept that man’s development could threaten thevery life systems of the earth, or that mankind could cause major extinctions. Homo sapiensnow appropriate between 20% and 40% of the solar energy captured in organic material byland plants. The Earth Summit of 1992 marked the moment when this crisis was recognised.

We are now committed to pursuing a policy of sustainable development and the monitoringof biodiversity is an essential element. The UK Biodiversity Action Plan of 1994 proposednational targets which could be used to measure the impact of development and highlightcases where policies are unsustainable. However since then at the national and internationallevel there has been only moderate progress in adopting sustainable policies. Much moreprogress has been made at the local level.

The Biodiversity Action Plan for Hampshire is an impressive example of how nationalobjectives can be translated into effective action at the county level. Without the knowledgeand commitment of the organisations within the Hampshire Biodiversity Partnership, therewould be little prospect of effective action. There is a great need for a comprehensivestatement on objectives and the means of implementation. This Plan provides a frameworkfrom which individual agencies and organisations can develop their own actions, partnershipprojects can be established, and progress can be monitored.

In May 1993 I chaired a seminar organised jointly by the Joint Nature ConservationCommittee and the Department of the Environment, at which key issues were identified forthe successful production of biodiversity action plans. We recognised then that the key tosuccess would be the active support and participation of as many people and organisations as possible.

Conserving biodiversity is not just about conserving the rare and endangered species, but alsoabout securing biodiversity in our everyday environment. We need to increase awareness ofthe biodiversity around us and we need to recognise that everyone can play a part. Those ofus who are fortunate enough to live in Hampshire now have the opportunity to put intoaction the proposals in the Biodiversity Action Plan for Hampshire.

Summary

The Biodiversity Action Plan for Hampshire is produced in response to a growing concernfor biodiversity in the UK and throughout the world. This has become a particularly importantissue since the signing of the Convention on Biological Diversity at the Earth Summit in 1992.As a nation, we pledged to develop a strategy to halt the decline of biodiversity. Part of thatstrategy is the production of local biodiversity action plans to address the variety of actionsrequired at the local level across the UK.

Local biodiversity action plans differ from previous approaches to nature conservation in twoimportant ways: they are prepared by a wide partnership of individuals and organisations, andthey follow a very disciplined approach to auditing and target setting. The plans aim to ensurethat national targets are translated into effective action at the local level, and that importantlocal features are also fully included in strategies for action.

The Hampshire Biodiversity Partnership has been formed to advance the conservation andenhancement of biodiversity in Hampshire, and preparation of the Biodiversity Action Plan isthe first main task. The Plan will provide a strategy for action in two volumes: Volume 1, thestrategic framework and main courses of action, and Volume 2, the detailed action required forpriority habitats and species in the county.

The Biodiversity Action Plan provides the platform from which the Partnership will take action.Each partner organisation can review their own programmes and approaches to biodiversityagainst the objectives and targets outlined in the Plan. The Partnership will play a vital role instimulating and co-ordinating action, monitoring progress and reviewing priorities.

To advance biodiversity conservation in Hampshire, the Partnership has identified the following objectives:

• to audit the nature conservation resource of Hampshire

• to identify from the audit habitats and species of priority nature conservation concern,including those which are locally distinct

• to prepare action plans for habitats and species of priority concern and follow through withprogrammes of implementation and monitoring

• to ensure that data on habitats and species is sufficient to enable effective implementationand monitoring of biodiversity objectives

• to review general issues affecting biodiversity, such as agriculture and development,and chart a course of appropriate action

• to raise awareness and involvement in biodiversity conservation across all sectors

• to encourage individuals and organisations to review their role in biodiversity conservationand the resources required, and develop their own action in response to the BiodiversityAction Plan for Hampshire

• to maintain an ongoing partnership which will co-ordinate, develop and support action for biodiversity

• to monitor and review progress towards meeting the above objectives and the targets setout in the habitat and species action plans

• to periodically update the Biodiversity Action Plan for Hampshire and its componenthabitat and species action plans to take account of changing circumstances

The Biodiversity of Hampshire

Hampshire is one of the richest areas for wildlife in England. Nevertheless the county hassuffered immense losses during the past 200 years. Many habitats have been lost to builtdevelopment, or become degraded through changes in agricultural practice and afforestation.There is a pressing need to conserve those areas that remain and enhance or restore otherareas of valuable wildlife habitat. The Hampshire Biodiversity Partnership has undertaken anaudit of habitats and species to determine their extent and distribution as well as past trendsand losses. The audit is an essential component of the Biodiversity Action Plan and enables theidentification of priority habitats and species: these will be addressed in detailed action plansfor individual habitats and species.

Habitats

Of the UK’s 37 broad habitat types, 23 are found in Hampshire. Within the broad habitattypes, ‘key’ habitats of priority importance have been identified. In Hampshire, 18 key habitatsof UK conservation concern are present, and there are an additional 3 habitats of localconcern. Detailed habitat action plans will be written for these 21 priority habitats to fullyreview their current status and set objectives and targets for action.

Species

The richness of habitats in Hampshire is reflected in the wide range of species found. The UKBiodiversity Programme has identified 1288 species of national conservation concern, and ofthese, 489 priority species require urgent conservation action. Of the 489 national priorityspecies, 196 are found in Hampshire, and the audit has identified an additional 248 priorityspecies which are particularly important in the local context. Action for most of the priorityspecies in Hampshire will be covered by relevant habitat action plans. Where national speciesaction plans exist, these will be translated into specific action in Hampshire. For those speciesnot covered by national plans or which can not be easily accommodated by a habitat actionplan, a specific species action plan will be prepared.

Geographical Variation

The distribution and location of habitats and species of conservation concern needs to beunderstood so that action can be targeted appropriately. Variation in the landscape andecological character of Hampshire has been described in three map-based classifications:Hampshire County Council’s Landscape Character Areas and Landscape Types; theCountryside Commission’s Character Areas; and English Nature’s Natural Areas. Each of theseclassifications can help to identify biodiversity issues, such as hedgerow loss, which requiretargeted action across a wide geographical area.

Urban areas have a particular biodiversity character of their own and it is therefore particularlyimportant for the Biodiversity Action Plan to address urban issues. An action plan for urbanareas will be prepared along with those for the other key habitats of conservation concern.

Habitat and Species Action Plans

Detailed habitat action plans for 21 key habitats are in preparation. For the 443 priorityspecies brief statements will be prepared. These will make the link with the relevant actionplan (national species action plan, Hampshire habitat plan, or Hampshire species action plan).

Volume 2 of the Biodiversity Action Plan will include all of the Hampshire habitat action plans.It will also identify the relevant action plan that has been, or will be, prepared for each priority species, and include some species action plans. More will be added as they become available.

Page 8: Biodiversity pages 1-44 · Biodiversity Action Plan for Hampshire 4 Foreword When 150 heads of government signed the Convention on Biological Diversity at Rio de Janeiro in June 1992,

Habitat and species action plans will have several goals:

• to provide information

• to identify conservation issues

• to establish comprehensive targets for action

• to direct conservation action

• to raise awareness

• to provide a monitoring framework

Each plan will follow a standard format. Some plans will be prepared by working groups andothers by a lead partner. Each will undergo wide consultation to ensure that plans arecomprehensive, accurate, forward thinking and widely supported. A lead agency will beencouraged to oversee the implementation of plans most relevant to their own area of work.

ACTION

• prepare action plans for 21 habitats

• prepare detailed action plans for individual priority species where these are not catered for by a national species action plan or Hampshire habitat action plan

• establish working groups or lead partners to prepare and promote the implementation of the plans

• identify a lead agency to adopt each habitat and species action plan and take the lead inmonitoring, co-ordinating and encouraging action

• involve existing fora and projects in delivering action, for example the Farming and WildlifeAdvisory Group, Hampshire Woodland Forum and Hampshire Heathland Project

• establish partnership projects and initiatives to help implement action

• encourage individual partners to identify objectives and action relevant to their own activitiesand integrate these, with specific targeting and action, into their work programmes

Information and Data

The collection of data on habitats and species is fundamental to the development andimplementation of the Biodiversity Action Plan and indeed to the whole biodiversityprogramme. A large amount of data on the biodiversity of Hampshire is already held on theHampshire Biological Record at Hampshire County Council. However, there is still a lot ofinformation to be obtained and a need to co-ordinate current data.

The UK Biodiversity Steering Group recommends the development of local biological recordcentres to serve local needs and contribute information at the national level. The existingHampshire Biological Record could be developed into a Hampshire Biological Record Centreas part of the National Biodiversity Network. This would capitalise on data and informationsystems already available and ensure the full complement of services required to support theHampshire Biodiversity Partnership and the biodiversity programme.

Summary

Biodiversity Action Plan for Hampshire

ACTION

• continue to undertake detailed habitat survey of Hampshire in support of biodiversityconservation, using the Hampshire Habitat Survey Project

• encourage, support and co-ordinate a voluntary network of recorders to assist in providing dataon biodiversity

• encourage the centralisation of data on habitats and species into the Hampshire BiologicalRecord and use this database for monitoring progress in biodiversity action

• progress the development of a Hampshire Biological Record Centre to service the HampshireBiodiversity Partnership and individual partners, and contribute to the National BiodiversityNetwork

• establish a programme to monitor land-use and habitat change using the digitised habitat andland-use mapping of the county as a baseline.

General Issues Affecting Biodiversity

The conservation of biodiversity is not only dependent on direct action for habitats andspecies. There are many wider issues that have a great influence on the welfare of wild plantsand animals. Two of the key issues in Hampshire are agriculture and development: farmingplays a pivotal role in determining the biodiversity of the countryside, and development hascaused extensive loss of wildlife habitat during the past 50 years.

Other issues affecting biodiversity include forestry, coastal management, recreation andtourism, water management, energy, transport, air quality and climate change. For these topicsthere are many different levels of action required and many different vehicles for pursuingaction. The Hampshire Biodiversity Partnership will support existing initiatives and encourageand support individual organisations in the formulation of their action for biodiversity. Whereappropriate, the Partnership will establish topic groups to address certain issues.

ACTION

• encourage organisations and individuals with a particular responsibility for land-use and landmanagement activities such as agriculture, development, forestry and water resources, toestablish their own specific objectives and action for biodiversity, taking particular account oftargets and action outlined in habitat and species action plans

• establish groups where appropriate to review issues influencing biodiversity and prepare plans of action

• develop action for biodiversity through appropriate land-use fora such as SERPLAN and theSolent Forum

• take full account of biodiversity objectives within land-use plans and strategies such as theHampshire County Structure Plan, local plans and Local Environment Agency Plans

• influence local and regional policy and national guidance, policy and legislation to supportbiodiversity objectives in Hampshire

Awareness and Involvement

One of the central aims of the Biodiversity Action Plan is to increase understanding andsupport for biodiversity throughout the county. This will involve many sectors of society andpeople in all walks of life. Messages on biodiversity need to reach everyone and focus on thebenefit of biodiversity conservation to us all.

Communication and action will have to be relevant to individual sectors. Their involvement,the support provided to them, and the action requested of them needs to be sensitive totheir particular concerns. An action plan will be prepared to specifically address awarenessand involvement. A working group from the Hampshire Biodiversity Partnership will formulatea marketing strategy to get the key messages of biodiversity across. Successful implementationof the Biodiversity Action Plan will depend on widespread understanding.

ACTION

• establish a working group to prepare an action plan to address awareness and involvement inbiodiversity conservation

• ensure that information on biodiversity and how to get involved in conserving biodiversity isreadily available to the public. Local authorities and voluntary conservation organisations inparticular can promote awareness and provide opportunities for involvement throughmechanisms such as grant-aid for community projects and the management of nature reserves

• promote the Biodiversity Action Plan for Hampshire and publicise the main objectives andprogramme of action

• develop a strategy for marketing biodiversity which targets key sectors such as farmers, businessand industry, all levels of government, the public, land managers and education

• encourage and support organisations in developing their corporate awareness and commitmentto biodiversity, for example within all departments of local government

• ensure that biodiversity is a central component of Local Agenda 21 programmes and thatAgenda 21 is a vehicle for promoting awareness and involvement

• support the integration of biodiversity conservation into formal education

The Way Forward

The Hampshire Biodiversity Partnership has a long-term vision for the biodiversity programmewhich stretches well into the next Millennium. The Biodiversity Action Plan marks thebeginning of a co-ordinated programme of projects, initiatives, and other courses of action:some can be progressed immediately, others will evolve over time. Each individual andorganisation concerned with the conservation of Hampshire’s biodiversity has a fundamentalrole in ensuring the success of the objectives of the Plan.

ACTION

• develop and maintain a long-term Partnership to progress the conservation and enhancementof biodiversity in Hampshire through developing initiatives, exchanging information, encouragingaction and monitoring and reviewing progress. This work will be assisted by the BiodiversityAction Plan Steering Group.

• encourage individual partners to review their own action, to help meet the objectives and targetsset out in the Biodiversity Action Plan and associated habitat and species action plans

• monitor the development of the UK Biodiversity Programme and other policies and initiatives at the national and international level, for integration into the Biodiversity Action Plan for Hampshire

• review and update the Biodiversity Action Plan, including the habitat and species action plans,every five years

BIODIVERSITY

Biodiversity - the variety of life on earth - is being lost at an alarming rate throughout the world.

The Government has established a programme for conserving biodiversity in the UK. A key element

is the preparation of local biodiversity action plans.

10

What is Biodiversity? Why does it Matter?

Biodiversity includes all species of plants andanimals, their habitats, and the complexecosystems that sustain them. Biodiversityincludes all living things - from sparrows oncity streets to rare creatures found inremote places.

Plants and animals are essential to our lives.It is our responsibility and in our self-interestto look after biodiversity now and for futuregenerations. There are many compellingreasons for doing this: some are moral,others are aesthetic or economic.Biodiversity provides food, medicines,water, and even the oxygen in the air thatwe breathe.

REASONS FOR CONSERVING BIODIVERSITY

Biodiversity supports life itself - Most specieshave a precise role to play in the Earth’s well-being. Many plants and animals aredependent upon each other in a complex webof life, with each species relying on others forsurvival.

Biodiversity provides essential goods - Plantsand animals provide food, medicines, clothingand some of the raw materials for buildingand industry. It is vital to conservebiodiversity to maintain a wide range ofspecies for future use.

Biodiversity helps to maintain theenvironment - Natural processes assist withflood control, prevent soil erosion, help to filterwaste water, clean pollutants from the air, andmitigate noise and the visual intrusion ofdevelopment. Biodiversity also acts as anindicator of the health of the environment andis a key test of sustainability.

Biodiversity has aesthetic and spiritual value -People benefit greatly from contact with thenatural world. Quality of life is intimatelylinked with the health of the environment.Many people value the very existence ofspecies and habitats even if they have nodirect contact with them.

Biodiversity is valuable for recreation - Manypeople enjoy recreation in the countryside andurban nature areas. Attractive landscapes andwildlife are a focus for tourism and veryvaluable to local economies.

Biodiversity

The loss of biodiversity is important toeveryone. During the past 50 years, therehas been an unprecedented rate of loss ofwild plants and animals across the UK.More than 100 species are thought to havebecome extinct here in this century. If thepollution of the air, land and sea, and thedestruction of habitats continues, people areultimately the losers. Action to reverse thecurrent trends is needed now. Asindividuals or organisations, everyone canassist with the conservation of biodiversity.

The Global Challenge

The Convention on Biological Diversity wassigned at the Earth Summit in Rio deJaneiro in 1992. The United Kingdom wasone of 150 countries that pledged todevelop a national strategy for ‘theconservation and sustainable use ofbiological diversity’. The Conventionsignalled global concern that habitats andnatural ecosystems were being lost at analarming rate. Each country recognised thatit had a responsibility to halt the decline ofbiodiversity within its boundaries.

UK Strategy

The UK Government was one of the firstsignatories to the Convention to produce abiodiversity strategy and action plan inJanuary 1994 - Biodiversity: The UK ActionPlan1. The report outlines the broadstrategy for conserving and enhancingbiodiversity in the UK for a 20 year period.

Although the Plan set broad goals andobjectives, it was recognised thatimplementation would require detailedtargets. The UK Biodiversity Steering Groupwas established with the task of preparing adetailed programme of action.This grouphad a wide membership includingrepresentatives from national agencies suchas English Nature and the EnvironmentAgency, local government, farming and landmanagement, voluntary conservation bodiesand industry.

Biodiversity: The UK Steering Group Report2,published in two volumes in December1995 and endorsed by the Government inMay 1996, advocates four key elements toachieve biodiversity objectives:

• development of action plans with costedtargets for key species and habitats

• improving the handling of informationand data

• raising awareness and involvement

• the production of Local BiodiversityAction Plans

Each of these topic areas is now beingaddressed under the UK BiodiversityProgramme. Central to this is thepreparation of national action plans forhabitats and species of particularconservation concern: 38 habitat actionplans and over 400 species action plans willbe produced during the next few years.Many have already been written. The planswill have clear objectives and quantified andcosted targets, enabling progress to bemonitored in the long-term. This is a newand much more disciplined approach tonature conservation in the UK.

The UK Biodiversity Programme is beingsteered by the UK Biodiversity Group whichhas replaced the former UK SteeringGroup. The various elements of theProgramme are being overseen by a rangeof sub-groups. Also reporting to the UKBiodiversity Group are groups for England,Wales, Scotland and Northern Irelandwhich help provide information and supportbiodiversity action within each area.

Local Biodiversity Action Plans

The Government has taken a lead in settingthe approach for biodiversity conservation.But to succeed, action needs to be taken atall levels and in all sectors of thecommunity. One of the essential means ofachieving national objectives for biodiversityis through the preparation of LocalBiodiversity Action Plans. Biodiversity:The UKSteering Group Report has clearly advocatedthe preparation of Local Biodiversity ActionPlans and sees them as a fundamentalcontribution to Local Agenda 21programmes. Local Biodiversity ActionPlans have two broad functions:

• to ensure that national action plans aretranslated into effective action at the local level

• to establish targets and action for speciesand habitats characteristic of each local area

Local Biodiversity Action Plans differ fromprevious approaches to nature conservationin two important ways: they are preparedby a wide partnership of interestedindividuals and organisations, and theyfollow a very disciplined approach toauditing and target setting. The Plans formthe framework from which individualmembers of biodiversity partnerships candevelop strategies for delivering relevantparts of the Plan.

FUNCTIONS OF LOCAL BIODIVERSITYACTION PLANS

To ensure that national targets for species andhabitats, as specified in the UK Action Plan,are translated into effective action at the locallevel. National priority species and habitatsoccurring in the local area must be identified;targets should be linked to national priorities.

To identify targets for species and habitatsappropriate to the local area, and reflect thevalues of people locally. Local BiodiversityAction Plans can highlight important localfeatures and provide an opportunity for peopleto express their views about what is importantin their area.

To develop effective local partnerships toensure that programmes for biodiversityconservation are maintained in the long term.The Local Biodiversity Action Plan must bebuilt by consensus. The Plan should be ownedby all parties that have a key role in deliveringaction.

To raise awareness of the need for biodiversityconservation in the local context. Increasingpublic awareness and involvement inbiodiversity conservation is crucial for success.

To ensure that opportunities for conservationand enhancement of the whole biodiversityresource are fully considered. Plans need toconsider appropriate action for differentlocalities within the plan area. Opportunitiesfor habitat enhancement and restorationshould be pursued in addition to conservationof the existing resource.

To identify the resources available forimplementing the objectives of the Plan.

To provide a basis for monitoring progress inbiodiversity conservation, at both local andnational level. A periodic review of whethertargets have been achieved will assess theeffectiveness of the plan and contribute tonational monitoring.

The Hampshire Biodiversity Partnership hasbeen established to advance biodiversityconservation and enhancement inHampshire. One of the first functions ofthe Partnership has been to prepare thisBiodiversity Action Plan. The Plan willprovide a focus for everyone involved andguide action on conservation for thecoming years. This will mark the beginningof a process of implementation which willcontinue well into the next Millennium.

The Partnership embraces a wide range oforganisations - local authorities, statutoryconservation agencies, voluntary bodies,representatives of landowners and others -all working together with the common goalof conserving Hampshire’s biodiversity. ThePartnership will undoubtedly expand as theprocess of conserving biodiversityprogresses. Additional partners from manysectors of society will be particularlyvaluable as each can bring their own skills toformulating and implementing the Plan.

The Biodiversity Action Plan

The Plan consists of two parts. Volume 1sets out the overall strategy for biodiversityaction and the key objectives. Volume 1also:

• explains the audit of habitats and speciesundertaken in Hampshire

• outlines how the Partnership hasselected habitats and species of priorityconcern

• reviews geographical variation inbiodiversity

• identifies data needs

• summarises the main issues influencingbiodiversity

• examines the raising of awareness andinvolvement in biodiversity conservation

Detailed action plans will be prepared forhabitats and species of priority concern.

Volume 2 will contain action plans forpriority habitats and will identify the actionplans that have been, or will be, preparedfor priority species. Some species actionplans will be included at the outset, otherswill be added as they become available.Together, the overall strategy of action in

A BIODIVERSITY ACTION

PLAN FOR HAMPSHIRE

The Hampshire Biodiversity Partnership is co-ordinating action for biodiversity in Hampshire andhas formulated a comprehensive strategy. The Biodiversity Action Plan will stimulate a growing webof conservation action and each partner will have a particular role to play.

chapter 2

Volume 1 plus the detailed action plans forhabitats and species, will provide aprogramme for biodiversity conservation inHampshire. This will be reviewed andupdated every five years.

The Process

The Biodiversity Action Plan provides theplatform from which the Partnership willtake action. It will also enable eachorganisation to develop their own ideas andapproaches to biodiversity, or cometogether collectively to implement jointprojects and address strategic issues. Therewill also be opportunities to implementaction for biodiversity by building onexisting initiatives.

Action stemming from the Plan will be veryvaried. Within the habitat and species plans,recommended action will cover aspectssuch as site protection, habitat managementand restoration, data needs and policymatters. From the strategic action pointsset out in this document, detailedprogrammes of action will be developed, forexample to deal with data needs or theraising of awareness and involvement inbiodiversity conservation. Within eachsubject there will be a variety ofmechanisms at many levels for deliveringobjectives. To assist implementation of theplan, lead agencies will be identified to co-ordinate action.

Roles and Contributions

Implementation of the action will include awide range of functions such as land-useplanning, provision of grant-aid and landmanagement. Each partner will have aparticular role to play: for example,planning is the remit of local authorities;giving grants and incentives is one of thefunctions of the Ministry of AgricultureFisheries and Food; land management is aprimary responsibility of farmers; andcommunity action can be fostered bybodies such as the Hampshire Wildlife Trustand parish councils.

The Plan will stimulate a growing web ofaction. Success will largely rest on thecommitment and enthusiasm of individualpartners. However, the Partnership will playa vital role in stimulating and co-ordinatingaction. Through effective networking andinformation exchange, the Partnership willhelp to minimize duplication and insteadbuild co-operation so that best use is madeof the expertise and resources available.The Partnership will also undertake thefundamental role of monitoring progressand reviewing priorities.

What’s New?

Much is already being done for biodiversityconservation in Hampshire. There is a greatrange of existing projects and initiatives anda variety of mechanisms. Nevertheless, theBiodiversity Action Plan process brings anew discipline to this work. It provides theopportunity to review current activities,identify priorities and set specific targets. Italso provides a clear framework forreviewing and monitoring progress. Eachorganisation can analyse its own programmeof work against the agreed priorities of theHampshire Biodiversity Partnership, and thenational targets laid down in the UKBiodiversity Action Plan.

Although organisations with an interest inbiodiversity conservation have workedtogether before, the scale of the HampshirePartnership is unique. Partners from adiverse spectrum of organisations andagencies have agreed to joint responsibility.This is the first time that there has beensuch a co-ordinated approach tobiodiversity both nationally and in thecounty. This should translate into anunprecedented degree and range of actionfor biodiversity.

Links with Other Plans

The UK Biodiversity Action Plan sets thepriorities for all other biodiversity plans inBritain. In some areas, regional plans arebeing formulated to fit into the hierarchybetween national and local programmes.The South-east Regional Biodiversity Audit,essentially an audit of the habitats andspecies of conservation concern within theregion, will assist counties in matching theirpriorities with each other, and with those inthe national guidance. In turn, theBiodiversity Action Plan for Hampshire willguide any further plans in the county, forexample at district level or withinorganisations.

A range of other plans and processes willhelp to deliver biodiversity objectives.Objectives and targets should be included inLocal Agenda 21 programmes, structure andlocal development plans, transport plansand many others. There are many plans andstrategies in existence or in preparationwhich address biodiversity issues: forexample Local Environment Agency Plans,coastal management plans and managementplans for specific areas such as the NewForest Special Area of Concern.

Each of these have a distinct role and arecontributing to biodiversity conservationwithin Hampshire. The biodiversityprogramme relies on a network of suchplans. In turn, the Biodiversity Action Planwill help to identify the need for furtherplans, help guide them, and support thereview of existing plans.

The habitat and species action plans willidentify relevant current action and existingplans and put these in the context of theoverall action required. Individualorganisations and agencies such as theEnvironment Agency, district councils,Ministry of Defence and Forestry Authoritywill be encouraged and supported in thepreparation of biodiversity action plans tocover their own areas of activity. In manycases, individuals responsible for themanagement of land may find it useful toprepare a plan which relates specifically totheir own landholding, and which forms partof their overall business plan.

STRATEGY FOR ACTION ONBIODIVERSITY

The Hampshire Biodiversity Partnership hasidentified the following broad objectives:

• to audit the nature conservation resourceof Hampshire (chapter 3)

• to identify from the audit habitats andspecies of priority nature conservationconcern, including those which are locallydistinct (chapter 3)

• to prepare action plans for habitats andspecies of priority conservation concernand follow through with programmes ofimplementation and monitoring (chapter 4)

• to ensure that data on habitats andspecies in Hampshire is sufficient toenable effective implementation andmonitoring of biodiversity objectives(chapter 5)

• to review general issues affectingbiodiversity, such as agriculture anddevelopment, and chart a course ofappropriate action (chapter 6)

• to raise awareness and involvement inbiodiversity conservation across all sectors(chapter 7)

• to encourage individuals and organisationsto review their role in biodiversityconservation and the resources required,and develop their own action in responseto the Biodiversity Action Plan forHampshire (chapter 8)

• to maintain an ongoing partnership whichwill co-ordinate, develop and supportaction for biodiversity (chapter 8)

• to monitor and review progress towardsmeeting the above objectives and thetargets set out in the habitat and speciesaction plans (chapter 8)

• to periodically update the BiodiversityAction Plan for Hampshire and itscomponent habitat and species actionplans to take account of changingcircumstances (chapter 8)

THE BIODIVERSITY OF

HAMPSHIRE

Hampshire is exceptionally rich in wildlife and diverse landscapes. But many habitats have been lost

or damaged, and there is a pressing need to conserve and enhance those which remain. The audit

has enabled the identification of habitats and species of priority concern.

Hampshire is one of the richest areas forwildlife in England. The county contains alandscape of remarkable contrasts and adiversity of habitats unparalleled in otherparts of south-east England. AlthoughHampshire is largely a rural county, thereare also large urban areas. The BiodiversityAction Plan aims to conserve all aspects ofthe county’s biodiversity: it is just as criticalto keep the commonplace common, askeeping the rare from extinction.

An audit is an essential first step toidentifying the quality and range of habitatsand species in the county. This has beencarried out by the Partnership and hasenabled the identification of habitats andspecies of national concern and Hampshireconcern requiring priority attention. Theaudit has identified the extent, quality anddistribution of wildlife habitats as well aspast trends and losses.

HABITATS

Diversity and Importance

Hampshire’s mosaic of habitats includesancient woods, wildflower meadows,heathlands, chalk downland, river valleys,coastal habitats, and the New Forest - thegreatest area of ‘semi-wilderness’ left inlowland England. Together these habitatssupport an exceptionally varied flora andfauna.

Sites of Special Scientific Interest (SSSIs) aredesignated to protect examples of Britain’smost valuable wildlife habitats. InHampshire, SSSIs cover 48,000 ha - some13% of the land area. This is about twicethe national average of 6.8%. Many of theSSSIs have been recognised for theirinternational importance too: 41,700 ha(about 11 % of Hampshire) have beendesignated (or are proposed) as SpecialAreas of Conservation (SACs) or Special

Protection Areas (SPAs) under EC Directives,and/or as Ramsar Sites under the Conventionon Wetlands of International Importance.

But this is only part of the picture.Statutorily designated sites protect onlysome of the best examples of Hampshire’shabitats. Sites of Importance for NatureConservation (SINCs) are also beingidentified within Hampshire, jointly byHampshire County Council, district councils,English Nature and Hampshire WildlifeTrust. The purpose of these is to helpconserve, and direct resources to, additionalareas of important wildlife habitat. Thisnetwork of locally designated sites currentlycovers a further 6% of Hampshire.

Even outside the specially recognised sites,the rest of the county is exceptionally rich.Scrub, field margins, hedgerows, ponds,mature trees and urban greenspaces allcontribute to Hampshire’s biodiversity andare of particular value to people in theireveryday lives.

Losses and Threats

Despite the richness and extent of valuablehabitat in Hampshire, the county hassuffered immense losses during the past 200years. Some habitats have declineddrastically in extent and have become veryfragmented. Many areas have been lost tobuilt development - houses, industry, roadsand marinas - or become degraded throughchanges in agricultural practice andafforestation. For example:

• 50% of ancient semi-natural woodlandhas been lost in the past 50 years

• over 90% of heathland has been lost innorth-east Hampshire in the past 200 years

• 98% of chalk downland has been lost inthe past 150 years

These statistics highlight the pressing needto conserve those areas that remain andenhance or restore other areas of valuablewildlife habitat.

Built development results both in outrightloss and in degradation due to secondaryimpacts such as increased water abstraction,loss of buffer zones and increased pressurefrom people. Changes in agriculturalpractice have caused the loss orimpoverishment of wildlife habitats throughalteration of drainage patterns, spraying withpesticides and herbicides, nutrientenrichment, or removal of farm featuressuch as hedges.

chapter 3

For each key habitat, a UK action plan hasbeen, or will be, prepared under the UKBiodiversity Programme. From the list of 38key habitats of conservation concern in theUK, 18 occur in Hampshire. An additional 3habitats have been identified by theHampshire Biodiversity Partnership as beingof local concern within the county: roadverges, canals, and urban habitats.

For each of these priority habitats a detailedaction plan will be prepared and included inVolume 2 of the Biodiversity Action Plan.The purpose of the 21 habitat action plansis to both reflect UK objectives and targetsfor habitats of particular conservationconcern, and to set appropriate localtargets. Action plans will fully review thestatus and current action for key habitats,and set detailed objectives and targets,identifying particular areas for urgent action.

These changes were largely supported andencouraged by successive governmentsstriving to ensure that Britain become moreself-sufficient in food production.Afforestation has also resulted in loss ordegradation of habitats, particularlyheathland and ancient woodland.

The dramatic rate of loss in the past hasdeclined and land-use practices such asagriculture and forestry are now muchmore sensitive to nature conservation.However, significant pressures remain: forexample space must be found for aconsiderable number of new homesbetween 2001 and 2011. Many valuablesites are also suffering from lack ofappropriate management.

An Audit of Hampshire’s Habitats

At the UK level, the whole land surface andsurrounding sea has been divided into 37broad habitat types. Hampshire contains 23of the UK’s 37 broad habitat types, andtogether these cover the entire land areawithin the county. At the UK level, keyhabitats have also been identified and theseare habitats of particular national concern.

Some key habitats match the broad habitattype - for example ‘calcareous grassland’ isboth a broad and key habitat - whereasothers are subdivisions of broad habitattypes - ‘arable farmland’ is a broad habitattype and ‘arable field margins’ is thecorresponding key habitat. Within the 37broad habitat types found in the UK, 38 keyhabitats of particular UK conservationconcern have been identified. Key habitatswere selected using one or more of thefollowing criteria:

• habitats for which the UK hasinternational obligations

• habitats at risk, such as those which arerare or have a high rate of recentdecline

• habitats which are functionally importantfor species inhabiting widerenvironments, for example spawninggrounds for fish

• habitats important for species ofparticular conservation concern

Marine Habitats

The national biodiversity programme isreviewing marine broad habitat types andthe selection of key marine habitats. TheHampshire Biodiversity Programme willincorporate marine habitats and thepreparation of relevant action plans whenthe national review has been completed.

BROAD HABITAT TYPES FOUND INHAMPSHIRE

The following summaries of the 23 broadhabitat types define what the habitat is, itsextent in Hampshire and its relativeimportance in the UK. Main factorsaffecting the status of each habitat are alsogiven. Fuller details of distribution andextent, factors affecting the habitat, and thebroad conservation direction required willbe given in Volume 2.

Broadleaved/Yew Woodland/Scrub

Hampshire contains approximately 42,000 haof broadleaved woodland - about 11% ofthe county - and a further 3,000 ha ofscrub. About half of this woodland isancient and has been in existence since theMiddle Ages.

Ancient semi-natural woodlands - thosewith stands of native trees not obviouslyplanted - are particularly rich and diverse inwild plants and animals. A characteristicfeature of many of these woods is springcarpets of bluebells - a feature which isquite particular to Britain.

Although Hampshire is of nationalimportance for this habitat, holding about5% of the UK resource of ancient semi-natural woodland, 50% has been lost toagriculture, mineral extraction, urbanisationand plantations in the past 50 years. Todaythe major threat is lack of traditionalmanagement practices such as coppicing.

Coniferous Woodland

Coniferous woodland accounts for about20,000 ha or 30% of Hampshire’s woodlandresource. Almost half of this type ofwoodland occurs within ancient woodlands.Other major complexes include largeplantations over former heathland.

Conifer plantations on chalk are generallybiologically impoverished, although the rides,glades and woodland edges often supportan interesting downland flora and fauna.Plantations over heathland, however, canretain valuable relic heathland communities,although this is generally more by luck thandesign. Some of these areas are ofinternational importance for theirpopulations of bird species such as nightjarand woodlark.

Lowland Pasture Woodland/Parkland

Pasture woodlands are landscapescomposed of a mosaic of extensivelygrazed, or once grazed, wooded and openhabitat. Hampshire is of nationalimportance for this habitat because of thelarge amount of pasture woodland locatedin the New Forest. Medieval deer parksalso contain important vestiges of woodpasture in more open communities ofpasture and ancient pollard trees. Althoughthere is some 600 ha of relic pasturewoodland and parkland recorded inHampshire, the total amount in the countyis unknown as it often occurs as unmanagedancient woodland, wooded common, or asscattered trees in farmland.

Pasture woodlands such as those in theNew Forest contain very old trees withtree-hole nesting birds and bats, lichens,fungi and deadwood invertebrates. This richassemblage of species can be ofinternational importance and is one of thereasons for recommending the New Forestas a Special Area of Conservation.

Major threats to this habitat are cessation ofgrazing and removal of dead wood and oldtrees. In many areas there is also a large‘generation gap’ between the very old andyoung trees which leads to loss of habitatcontinuity, usually caused by overgrazing inthe past.

Hedgerows

Hedgerows are linear features composed ofwoody species, sometimes raised on grassybanks. Hampshire retains a traditionalpatchwork of small fields, woods andhedgerows, particularly in the north andsouth of the county. Winding parishboundaries and ancient lanes are oftendefined by hedgerows, many in existencesince medieval times. Hedgerows are veryimportant ecologically, resembling woodlandedge and scrub habitats. Ancienthedgerows possess a particularly richvariety of trees, shrubs and ground flora,and in some landscapes, hedgerows are oneof the few refuges left for wildlife.

Factors affecting this habitat includedestruction, lack of management andmismanagement. Continued agriculturalintensification to create bigger fields, urbanexpansion, new roads and otherdevelopment all contribute to hedgerowdestruction, although in recent years netloss has slowed considerably. Lack ofmanagement leads to overgrown, gappyhedgerows which are less valuable towildlife. Some hedges are poorly managedand cut at the wrong time of the year, cuttoo short, or cut too frequently. All ofthese factors reduce the value ofhedgerows for biodiversity.

Arable Farmland

Arable land is either that which is undercultivation, or temporary grassland of lessthan five years. Approximately 37% or141,000 ha of farmland in Hampshire isarable: just below the national average of41%. The county provides about 3% of thetotal UK resource. It is Hampshire’s largestsingle type of land-use.

Despite the effects of agriculturalintensification, Hampshire still possesseswhat is probably the richest and mostdiverse arable weed flora of any county inBritain. Nevertheless, much of the wildlifeinterest is confined to field margins whereherbicides and competition from the cropcan be avoided.

A large number of insects spend part oftheir life cycle in cereal fields and they are asource of food for many birds andmammals including grey partridge, skylark,lapwing and corn bunting. The use ofherbicides and insecticides has led to adecline in many of these species.

Improved Grassland

Improved grassland is intensively managed,species-poor, and dominated by a fewspecies of grass. There are about 66,000 haof this habitat in Hampshire, 90% of thecounty’s grassland. This represents 31% ofall farmland or 17% of the county land area.

Improved grassland is sown for agricultureor amenity, or created by modification ofunimproved grassland by fertilisers andselective herbicides. Biodiversity is low. Fewplants other than competitive grassessurvive, and there is also a veryimpoverished fauna. The change over thepast two decades from hay to silage hasfurther degraded this habitat. Thesegrasslands may support a range of groundnesting birds such as lapwing and skylark ifmachinery is used infrequently and stockingdensities are low.

chapter 3

Unimproved Neutral Grassland/Fen

Unimproved neutral grasslands vary in theirpH and wetness and include marshy ‘fen’meadows associated with river floodplains,peaty ‘fen’ meadows associated with springsand flushes, wet and dry loamy/sandymeadows, and clay meadows. Surveys inthe 1980s show about 3,000 ha of thesemeadows in Hampshire. The total UKresource is now thought to be less than15,000 ha.

In Hampshire many of these areas comprisea mixture of wet and dry grassland. Theyare often associated with the flushes,streams and ditches of water meadows andmany are SSSIs. Most are managed asgrazed pasture, with few still managed astraditional hay meadows.

Herb-rich meadows are particularlyimportant due to a high proportion ofherbaceous plants, including many nowregarded as nationally uncommon: green-winged orchid, marsh helleborine and flat-sedge. Across the UK, 97% of this habitathas been lost between 1930 and 1984,making it one of the most endangered inBritain today.

Calcareous Grassland

Calcareous grassland is species-rich andoccurs on chalk or limestone. This habitatin Hampshire is very fragmented and mostlyconfined to the steep slopes of the centraldowns and the chalk escarpment in thenorth. Less than 2,800 ha - 5% of the UKresource - now remains. Nationally, anoverwhelming 95% of this rich habitat hasbeen lost during the past 50 years.

These grasslands contain an exceptionaldiversity of plant species, many now scarcein Britain. Many butterflies such as theadonis blue, duke of Burgundy and chalk hillblue are also in serious decline due to thesmall, fragmented nature of the remainingareas of chalk grassland.

Major threats to this habitat include lack ofmanagement, overgrazing, and agriculturalimprovements through application offertilisers and herbicides.

Floodplain Grazing Marsh

Floodplain grazing marsh is grassland whichis periodically inundated. The grassland itselfis generally improved, but ditches can berich in plants and invertebrates. Most sitesare grazed, although some are cut for hayor silage. Species-rich fen meadows foundin the floodplain are included in theunimproved neutral grassland/fen habitattype above.

Grazing marsh is very important forbreeding waders such as snipe, lapwing andcurlew, and internationally important forpopulations of wintering wildfowl such asBewick’s and whooper swans.

The main threats to this habitat includeagricultural intensification and associateddrainage, inappropriate ditch management,ground water abstraction, encroachingdevelopment and climate change which iscausing increased evaporation and lowerrainfall.

A mixture of open fen and carr can supportan exceptional range of plants, insects andbirds, and at one time the river valleys musthave been a continuous mosaic of thesehabitats.Today they tend to be isolated,separated by improved pasture and arableland. The amount of this resource inHampshire has been conservativelyestimated at 400 ha.

Fens are dynamic ecosystems and requiremanagement to maintain their opencharacter, otherwise they develop naturallyto scrub and woodland. Generally, thefactors affecting these habitats include lackof, or inappropriate, management, andfragmentation and loss caused by waterabstraction, drainage, encroachingdevelopment, and climate change. Futuresea level rise may lead to loss of reedbedsalong the coast through coastal ‘squeeze’.

Standing Open Water

Hampshire has a large number of lakes,ponds and gravel pits - as many as 500 lakes(> 0.5 ha) and over 1000 ponds (< 0.5 ha)scattered across the landscape. Thisresource has declined nationally by anestimated 75% over the past 100 years.

Lowland Heath/Bog/Acid Grassland

Lowland heathland is characterised by openexpanses of heather, gorse and cross-leaved heath on acidic soils, and generallyfound below 300m. Hampshire’s lowlandheaths are of international importance. Thecounty contains 16,000 to 17,000 ha -about 13% of the heathland left in Europeand 30% of the UK total. Much of theheathland is located in the New Forest, withthe rest scattered across the Thames Basin,Western Weald, and a few fragments insouth Hampshire.

Hampshire’s heathlands are particularlyimportant for birds, insects and spiders.They are also vital habitats for reptiles andamphibians: all 12 British species - includingsand lizard, smooth snake and natterjacktoad - are found here.

One of the greatest threats facing heathlandis lack of management. Fragmentation anddisturbance from development alsothreaten these very valuable areas.

Fen/Carr/Marsh/Swamp/Reedbeds

Fen, carr, marsh, swamp and reedbeds oftenoccur together and are scatteredthroughout Hampshire principally along theriver valleys and coast.

Species-rich fen tends to be inextricablyassociated with ‘fen-meadows’ and dryunimproved grassland, and so is largelyincluded in the broad habitat ‘unimprovedneutral grassland/fen’. Species-poor fen isoften associated with reedbeds and swampvegetation found along watercourses andaround pools of water. It commonly gradesinto fen-carr dominated by alder and willow.

chapter 3

Virtually all of Hampshire’s lakes are man-made and have been created to provide ahead of water for mills, fish for a nearbysettlement, or as part of the landscapesetting of country houses. More recently,lakes have been created in the river valleysof the Avon,Test and Blackwater as a resultof gravel extraction. Many are importantfor overwintering and breeding birds.

The majority of ponds are also man-made.Originally they were created to providewater for a village or for farm livestock, asdecoys for wildlife, or as a result ofabandoned clay pits. Today they tend to becreated for fishing purposes. Only a fewponds result from a naturally high watertable, but these tend to disappear duringhot, dry summers. Nevertheless, theyprovide ideal conditions for some rareinvertebrate species such as the fairyshrimp.

Neglect, infilling and eutrophication fromfertiliser run-off are major causes of declinein standing open water.

Rivers and Streams

Hampshire has some of the finest chalkrivers in Britain: the Test, Avon, Itchen andMeon, and a number of other rivers such asthe Lymington, Beaulieu, Loddon,Whitewater,Wey, Rother and Blackwater.

Chalk rivers are particularly important fortheir assemblages of plant species: theclarity of the water provides the lightneeded to stimulate luxuriant growth. Bedsof river water crowfoot, lesser waterparsnip and water starwort are host to avariety of invertebrates such as flatworms,snails, water bugs and beetles and are ofnational and international importance.

The chalk rivers of Hampshire are alsoimportant for fish: notable species includebrown trout, salmon, bullhead, brooklamprey and sea lamprey. The Avon,Testand Itchen are all notified as SSSIs, and theAvon and Itchen are also candidate SpecialAreas of Conservation (cSACs) for theirfloating vegetation of water crowfoot. TheAvon is also a candidate SAC because of itsfish populations.

Other rivers are important for other groupsof animals and plants according to theirnutrient status. For example, the more acidrivers of the New Forest and the RiverEnbourne along the northern countyboundary support a much richer dragonflyfauna than the chalk streams. In addition tothe chalk rivers mentioned above, theLymington is also an SSSI.

Current factors affecting rivers and streamsin Hampshire include: ground and surfacewater abstraction; pollution from sewage,fish farms and fertiliser and soil run-off;inappropriate bank management andengineering works; and climate change.

Canals

Hampshire once had several canals andriver navigations: the Itchen Navigation, theBasingstoke Canal, the Southampton andSalisbury Canal (with a branch to Andover),the Titchfield Canal and the Portsea Island Canal.

The Itchen Navigation was not a true canalbut a linked series of ‘cuts’. These havebeen replaced by weirs and the distinctiveslow-moving waters typical of canals havebeen lost.Very little of the Southamptonand Salisbury Canal remains except for asmall stretch of the Andover section near Romsey.

The 4 km Titchfield Canal, constructed inthe 1600s between the sealock at TitchfieldHaven and the then ‘Port’ of Titchfield, wasone of the first recorded canals in England.It became redundant within 100 years, buthas recently undergone some restorationwork. Part of it lies within the TitchfieldHaven National Nature Reserve.

The only sizeable canal remaining is theBasingstoke Canal. The 24 km in Hampshire(0.4% of the total UK resource of 6,400km) has become one of the mostimportant wetland habitats in the UK sinceit was restored between 1976 and 1991.This is due to the unusual transition fromcalcareous spring water in the west to moreacidic conditions in the east, resulting in anextremely diverse aquatic flora and fauna,including 24 species of dragonfly.

Potential threats to canals include increasedrecreational pressure, decreasing waterlevels, pollution and the presence of invasivespecies.

Maritime Cliffs

In Hampshire, maritime cliffs are soft anderodable and liable to cliff falls and slumping.They are nationally important for plant andanimal fossils and for their invertebrate fauna.

Open unstabilised areas of cliff areparticularly important for invertebrates.The main threat to this habitat is coastaldefence works: these isolate the cliff facesfrom the intertidal zone and encouragegrowth of stabilised slopes with scrub.Whilst erosion at the foot of the cliff isbeneficial to biodiversity, it is not so at thecliff top where valuable maritime vegetationneeds to be allowed to retreat landwards.The encroachment of urban developmentand cultivated land towards the seasqueezes and erodes this valuable resource.

Shingle

Much of the coastline of Hampshire iscovered by shingle beaches. This is sometimesmixed with sand or silt, and forms transitionsto other habitats such as saltmarsh andgrassland. Many shingle spits or beaches aremobile and therefore unvegetated:vegetation will only establish where there isa matrix of finer material such as sand orsilt, and the structure is stable. Vegetatedshingle is a nationally rare habitat.

Pioneer species on undisturbed shingle inHampshire include sea kale, the yellowhorned poppy and ‘little robin’ - a nationallyrare plant. Important fauna on shingleinclude breeding colonies of terns and anumber of nationally rare invertebrates.

Shingle is mostly threatened by recreationalpressure and sea defence works.

Saltmarsh

The Hampshire coast supports extensiveareas of saltmarsh: 2,660 ha or 6% of theUK total. Saltmarsh develops alongsheltered coasts and estuaries andrepresents a transition from mudflats whichare completely inundated by tides, to uppersaltmarsh which is infrequently inundated.Saltmarsh often grades into freshwatermarsh, shingle, heath, scrub and oakwoodland. These transitional habitats areparticularly valuable for invertebrates.

Over half of the saltmarsh in Hampshire isdominated by the hybrid cord-grass Spartinaanglica. The cord-grass marshes of theSolent are of international importance asthe original site for the introduction anddevelopment of this hybrid species nowfound worldwide. Other saltmarshes in theregion are more typical mixed communitieswhich support species such as glasswort,sea aster, sea purslane and a variety ofsaltmarsh grasses. Nationally importantcolonies of black-headed gulls and breedingterns are found on areas of saltmarsh, andthe majority are notified as SSSIs.

The main threats to saltmarsh include landreclamation for urban, port, transport andindustrial infrastructure, coastal defenceworks, waste disposal and recreationalpressures. The biggest threat in future islikely to be sea level rise and consequentcoastal squeeze.

Coastal Grazing Marsh

Coastal grazing marsh is low-lying,periodically inundated grassland, with ditchesthat contain standing brackish water andmay grade into saltmarsh. Although mostformer grazing marsh has been convertedto intensive agriculture or urban andindustrial use, extensive areas still remain inHampshire.These are some of the largestremaining areas of this habitat on the southcoast. They are of national natureconservation importance because they arespecies-rich and support internationallyimportant populations of wintering andbreeding birds, especially Brent geese.

This habitat grades into other importanthabitats such as reedbed, freshwater marshand ancient woodland. The total UKextent is unknown, but it is estimated thatthere are approximately 750 ha inHampshire.

Main threats to this habitat includeimproved drainage and management,pollution from sewage discharge andagricultural run-off, and cessation of grazing.Loss of habitat due to sea level rise will alsobe a problem if equivalent areas are notcreated elsewhere.

Sand Dunes

Sand dunes are windblown sand formationswith associated grassland and scrub.Thereare only two vegetated dune systems inHampshire, both on the south coast ofHayling Island, amounting to 110 ha. This isa tiny but valuable proportion of the UKtotal of 47,000 ha.

The sand dune systems are quite varied.One system has a rich fixed-dune florasupporting species such as dune fescue,sand cat’s tail and various unusual clovers,alongside mobile sand dunes which alsosupport many species local to Hampshire.The other system consists of a transitionfrom mobile sand dunes and stable shingleridges through to low-lying wet dune slacksand extensive dune-heath. Here large sandyareas support carpets of heather andlichens, with many nationally rare plants andinvertebrates.

The major threat to sand dunes is erosionfrom trampling: the south Hayling coastlinehas long been used for leisure andrecreation

Mudflats and Eelgrass Beds

These are areas of subtidal and intertidalsoft sediments, consisting of mixtures ofmud, sand and gravel. Often they supporteelgrass species in extensive beds whichhelp to stabilise the mudflats and allowinteresting marine communities to develop.They typically support a rich burrowingfauna of molluscs and worms and providean important nursery and feeding groundfor many fish species. They also provide avaluable food source for internationallyimportant populations of wintering waders,waterfowl and other coastal birds,particularly in the large sheltered harboursand estuaries of the Solent. There arearound 4,000 ha of this resource - about2% of the UK total.

Coastal defence work can interruptmovement of material along the coast andlead to depletion of mudflats. Sea levelrises will also reduce the extent of theseareas if they cannot retreat landwards.Mudflats are also particularly vulnerable topollution incidents such as oil spills orsewage discharges.

At least 1,000 ha of mudflats have been lostto development since 1930, reducing thebiological capacity of the Solent for fisheriesand wildlife. Losses have slowed greatlysince the majority of mudflats are nowdesignated as SSSIs, SPAs, Ramsar Sites andcandidate SACs.

chapter 3Saline Lagoons

Saline lagoons are open, shallow, brackish orsaline bodies of water which are completelyor partially separated from the sea by a beach,spit or seawall. Natural lagoons are very rare:most are modified or created by man but stillprovide a similar habitat with a comparablerange of specialised species. Saline lagoonsare considered a priority habitat under theEC Habitats Directive because of their highnature conservation importance .

The Solent area and adjoining harbourshave the greatest concentration of salinelagoons in Britain. Some 33 lagoons (95 ha)are found along the Hampshire coastline -7.3% of the UK total. At least 13 of theseare of national or international importancefor their communities of specialised plantsand invertebrates, including the lagoonshrimp, the starlet sea anemone and thefoxtail stonewort.

Saline lagoons are fragile habitats which aresusceptible to changes in salinity andpollution yet have only a limited ability tobuffer themselves from such changes.Theyare particularly threatened by anyalterations to their retaining barriers such asthose brought about by coastal defenceworks or a rise in sea level.

Road Verges

Road verges are ribbons of grass and scrubof varying width which may also containother habitats such as heath and woodland.Hampshire has about 10,000 km ofmotorway, trunk and minor roads, givingnearly 13,000 ha of road verge -approximately 3% of the county land area.

Road verges form a potentially importantand extensive habitat. Many pre-datemodern farming and provide an unbrokenlink with a former, more species-richcountryside. Others are more recent, butwith sympathetic management can supporta wide range of plants and animals.

Several factors currently affect this habitat:the lack of mowing beyond a one metrestrip which results in rank grassland andscrub replacing more important species-richgrassland, road widening, fertiliser run-offand spray drift from adjacent farmland, andthe laying of pipes and cables. Allcontribute to a decline in biodiversity.

Urban

Urban areas have an important biodiversitycharacter of their own. They containremnants of countryside and river corridorsas well as habitats that have taken hold inindustrial landscapes and those createdwithin parks, open spaces and gardens. Thelargest urban areas in Hampshire areSouthampton, Portsmouth, Basingstoke,Andover, Farnborough and Aldershot.

Remnants of former countryside includeSouthampton Common, a very rich area ofgrassland most of which is an SSSI, andancient woodland found within built-upareas. Most urban areas also containhabitats that have developed alongsideindustrial landscapes such as railwayembankments or vacant lots. Other greenareas such as urban parks, greenways andnature parks, have been specifically createdto provide open space, and each urban areahas significant numbers of private gardenstoo. All of these types of greenspaceprovide habitats for wildlife and access tonature for thousands of people who live inHampshire’s towns and cities.

Development should be carefully plannedto protect and provide urban greenspace.Managers of these areas need to balancethe conservation and enhancement ofbiodiversity and the provision of attractiveplaces for recreation and enjoyment.

SPECIES

Diversity and Importance

Hampshire is very rich in a wide range ofspecies. This is due to a number of factors:

• the merging of two climatic zones

• the county's situation on the coast

• the broad extent and stability of aconsiderable range of habitats

• the New Forest

Hampshire lies at the junction of twoclimatic zones and is fortunate to havespecies that are typical of both. Somewestern or oceanic species reach theeastern edge of their range - for instancewestern gorse and the marsh fritillarybutterfly. Similarly, some eastern orcontinental species reach the western edgeof their range - ground pine, wall bedstraw,and small cord-grass. The county is also thefirst landing point for some species fromcontinental Europe.

Hampshire has a variety of coastal habitats,including extensive saltmarshes and coastallagoons, which have their own distinctivewildlife. These habitats support a number ofspecies absent from inland counties.

Compared to the rest of south-eastEngland, Hampshire has a wide range ofhabitats, and many large areas valuable towildlife have remained comparativelyunchanged for long periods. This stableenvironment has allowed many species with very specific habitat requirements topersist. For example, species characteristicof old grasslands and ancient woodlands are widespread. Such habitats areincreasingly rare in the UK and this makes a very large number of the species theysupport of international or nationalconservation concern.

The New Forest is a special case. It is thelargest expanse of semi-natural habitat inthe lowlands of north-west Europe and isextremely rich in fungi, lichens, bryophytes,vascular plants, invertebrates andvertebrates, many of which are foundnowhere else in Britain.

Losses and Threats

Species can be threatened by a range offactors which can affect individual organismsor their habitat. They can be grouped underthe following headings:

• changes in habitat

• pollution

• species effects

• direct human impacts

• genetic effects

Species can be affected by a reduction in theoverall extent of their habitat, fragmentationof the habitat, or changes in habitat quality.For example, the marsh fritillary butterflyhas been driven close to extinction astraditionally managed damp pastures andmeadows have been reduced in extent bydevelopment, agricultural improvement andabandonment. These grasslands now oftenoccur in patches too small to support aviable population of the butterfly.

Some species are particularly sensitive tothe direct effects of pollution. Lichens arewell known as sensitive indicators of airpollution, and similarly, freshwater molluscscan be used as bio-indicators in aquaticenvironments.

Some species may be adversely affected byother species, through competition, diseaseor predation. For example, the nativewhite-clawed crayfish has undergone a verymarked decline since the introduction ofseveral species of North American crayfishinto Britain’s open waters.The Americanspecies have been aggressive competitorsand carry a fungal disease lethal to thenative species.

The populations of some species may bedirectly reduced by the collecting or huntingactivities of people. Several species oforchid and fern have had their populationsdrastically reduced or even brought close toextinction by enthusiastic collectors in thepast. Human disturbance can have similarconsequences. Disturbance is a particularlyimportant factor in the reduced breedingsuccess of several species of bird,particularly waders nesting in open habitatssuch as wet grasslands in river valleys andshingle on the coast.

Some species may also be threatened bychanges in their genetic make-up. Thoughthe genetics of wild species are generallypoorly understood, issues include theintroduction of alien varieties of nativespecies, such as the Spanish bluebell, and therelease of genetically modified organismsinto the environment.

An Audit of Hampshire’s Species

The UK Biodiversity Programme hasidentified 1288 species of nationalconservation concern.

CRITERIA FOR SELECTING SPECIES OFNATIONAL CONSERVATION CONCERN

• threatened endemic and other globallythreatened species

• species where the UK has more than 25%of the world or appropriate biogeographicalpopulation

• species where numbers or range havedeclined by more than 25% in the last 25 years

• in some instances, where the species isfound in fewer than 15 ten-km squares inthe UK

• species which are listed under internationalconventions or legislation (e.g. EC HabitatsDirective, EC Birds Directive, BernConvention, Bonn Convention, CITES,Wildlife & Countryside Act 1981)

Of these, 489 species of particular concern(rapidly declining or globally threatened)have been selected as priority species.National action plans have been or will beprepared for the majority of the priorityspecies. These plans set targets and a broadframework for action, but to be effectivethey must be translated into local contextsthroughout the UK.

The audit in Hampshire follows the nationalapproach by identifying species of concernand priority species within the county. Theaudit has taken account of all the nationalspecies of conservation concern andnational priority species which occur inHampshire, as well as identifying additionalspecies within the county.

Species of Concern

Species of concern in Hampshire include allthe species of national conservationconcern which occur in the county, speciesidentified from Biodiversity Challenge4 (anaudit of nationally important speciesundertaken by a consortium of voluntaryorganisations) and other species of localconcern. These additional species of localconcern were nominated by variousexperts and specialist groups and aregenerally regarded as rare, declining,threatened or found in significant numbersin the county. In Hampshire, 776 species ofconcern have been identified.

EXAMPLES OF SPECIES OF NATIONAL CONSERVATION CONCERN OCCURRING IN HAMPSHIRE

Endemic Species

There are dozens of species which occur in the UK and nowhere else on Earth. Many are severelythreatened and the UK has an international responsibility to ensure that they do not becomeextinct.

• Early gentian - a nationally scarce species of chalk grasslands which occurs in a few scatteredpopulations in Hampshire.

Globally Threatened Species

Many species occurring in Britain are threatened with world-wide extinction. Action in Hampshire isan important part of the international effort to maintain these species on Earth.

• White-clawed crayfish - declining across Europe and now occurring in only six small populationsin the county.

Internationally Important Numbers of Species

There are many species in the UK which occur in internationally significant numbers. Where the UKhas a large proportion of the world or European population, it is important to safeguard them inHampshire, even if they may seem common in the county.

• Bluebell - the UK has approximately 25% of the world’s population of bluebell. Britain’s bluebellwoods are unparalleled on the continent and Hampshire is particularly well-endowed with thesewoods.

Rapidly Declining Species

Large numbers of species have declined dramatically in numbers or range this century. Somechanges may be natural, but most have been brought about by human activities. Many farmlandbirds which were once common, widespread and familiar, have suffered drastic reductions in the UK.

• All of the following bird species are found in Hampshire and have declined by more than 50% inthe UK between 1969 and 1994: tree sparrow, grey partridge, corn bunting, turtle dove,bullfinch, spotted flycatcher, song thrush, lapwing, reed bunting, skylark, linnet.

Nationally Rare Species

Many species occur at very low population levels in the UK and this puts them at an increasedthreat of extinction. Some are naturally rare, whereas others have become rare due to humanactivities. In general, the former require surveillance to ensure that they do not become any rarer,and the latter require conservation measures to prevent their extinction.

• Slender cotton grass - confined to moderately acid valley bogs in the New Forest and believed tobe extinct in the rest of Hampshire. This plant has always been rare in the UK, but is nowparticularly threatened by scrub encroachment through lack of grazing.

Legally Protected Species

These species are protected under the Wildlife and Countryside Act 1981, the EC Birds Directive, orthe EC Habitats Directive. They are given greater legal protection against killing, taking, disturbance,destruction or damage to their habitat than species which are not legally protected.

• Great-crested newt - protected under both the Habitats Directive and Wildlife and CountrysideAct. It can still be found in many of Hampshire’s ponds and lakes.

Priority Species

Priority species are those species ofconcern which are in most need ofconservation action. They include allnational priority species which occur in thecounty - 40% of the national total occur inHampshire. In addition, other priorityspecies have been selected from the speciesof concern in Hampshire using informationon the following:

• significance of local population in regionaland national context

• local decline

• local rarity

• local threat

The full information gathered for eachspecies and the detailed method ofselecting priority species is given in Annex 1.In total 444 priority species have beenidentified, and these are listed in Annex 2.

EXAMPLES OF SPECIES OF LOCAL CONCERN IN HAMPSHIRE

Rare

• Rough horsetail - only ever recorded at twosites in Hampshire, but persisting in both.

Declining

• Scarce blue-tailed damselfly - declineddrastically in the New Forest in the past 10years, from occurring in 28 to 1 km square.

Threatened

• Bulbous foxtail - a grass of damp hollowsin traditionally managed coastal grazingmarshes. Threatened by changes ingrassland management, lack of tidalflooding, loss of habitat as sea defences areretreated, and development pressures.

Significant Populations

• White-letter hairstreak - a little knownbutterfly which breeds on elm trees. South-east England is a stronghold for the speciesand Hampshire has a thriving population.

• Hampshire purslane - a prostratewillowherb of muddy places and ponds stilllocally common in the New Forest. Thisplant is not reliably recorded anywhere elsein the UK.

Several of the priority species identified inHampshire are extinct in the county orpossibly extinct. It is important that theHampshire Biodiversity Programme takesaccount of those species once occurring inHampshire that have disappeared. Wherethese species persist elsewhere they mayreturn of their own accord if conditions aresuitable.

Action for Priority Species

Conservation action for most priorityspecies can be dealt with through habitataction plans. The majority of species willbenefit from positive habitat managementand will be well catered for in these actionplans. However, there remains a number ofspecies with very special requirements.Species action plans will be needed whereone of the following criteria applies:

• the species is so highly threatened, orrapidly declining, that urgent action mustbe taken to prevent local extinctions

• the species is widespread and found in arange of different habitats and will bevery difficult to conserve throughgeneral habitat work without specificaction

• the species, although restricted to aparticular habitat type, has such peculiarecological requirements that normalhabitat management will not cater for it

Relatively few species action plans will beneeded in Hampshire. Most species will becatered for in Hampshire habitat actionplans or national species action plans.

Brief statements will be prepared for eachof the 444 priority species. Thesestatements will make the link with therelevant action plan. For example, where anational species action plan exists, thestatement will translate the national planinto specific action and targets forHampshire.

Monitoring

A database has been established whichincludes information on all the 776 speciesof concern in Hampshire. This will beupdated as additional information on thestatus of species becomes available, and maylead to species being added to, or taken offthe priority list. The database will also keeptrack of relevant conservation projects andcurrent action on each species.

• English Nature have classified Englandinto ‘Natural Areas’, 8 of which occur inHampshire.This classification is verysimilar to the Countryside Commission’s,except that within Hampshire four of theCountryside Commission CharacterAreas have been combined into twoNatural Areas.The CountrysideCommission and English Natureclassifications are illustrated anddescribed in The Character of England6.

All three classifications are being used toidentify issues that are influencing orimpacting on the landscape and ecologicalcharacter of the county. For example,some landscape areas have sufferedconsiderable hedgerow loss and wouldbenefit from hedgerow planting andmanagement. Others would benefit fromheathland or downland restoration.

Both the Countryside Commission andEnglish Nature have published profiles foreach Character Area and Natural Area,which describe each area and the issuesinvolved in conserving or enhancing theircharacter. At a more detailed level theCounty Council, together with otherpartners, is preparing a comprehensiveLandscape Strategy for Hampshire: this willidentify issues and courses of actionrequired across a whole range of topics thatinfluence landscape and ecological character,and relate these to each of the CountyCouncil’s Character Areas and LandscapeTypes. The Hampshire Landscape Strategywill help guide the plans, policies and actionof a whole variety of organisations andgreatly assist the biodiversity programme.

GEOGRAPHICAL VARIATION OF BIODIVERSITY

Knowledge of the distribution and locationof habitats and species of conservationconcern is important. Understanding thisgeographical variation helps to target actionto appropriate areas.

Landscape Character Areas and NaturalAreas

Variation in the landscape and ecologicalcharacter of Hampshire has been defined bythree map-based classifications, and thesecan be used to support the biodiversityprogramme:

• At the most detailed level, HampshireCounty Council has divided the countyinto 11 ‘Landscape Character Areas’ andthese have been further subdivided into20 ‘Landscape Types’.The classification isdescribed in The Hampshire Landscape5

and is being used and refined by districtcouncils for district landscapeassessments.

• The Countryside Commission hasdivided the whole of England into‘Countryside Character Areas’, 10 ofwhich occur in Hampshire.Theboundaries of these CountrysideCharacter Areas were influenced by theHampshire County Council classification,and the two classifications are virtuallysynonymous.The main difference is thatthe Countryside Commission mapexcludes the river valley character area.

Land-use and Habitat Maps

Two other sources of information areparticularly useful for defining the extentand distribution of habitats. Acomprehensive map of land-use andhabitats in Hampshire has been producedfrom the interpretation of aerialphotographs. The project, undertaken onbehalf of Hampshire County Council during1996-97, has classified the entire landsurface of the county on a ‘field-by-field’basis using 81 land-use/habitat categories.The mapping is held in digital form for useon Geographical Information Systems (GIS).This provides a particularly powerfulanalytical tool for identifying the locationand area of specific habitats, and formonitoring land-use change over time. Themapping will be an invaluable informationresource for the biodiversity programme.

In addition, Hampshire County Councilholds many detailed site records collectedby ground survey which are stored on theHampshire Biological Record. Thisinformation is useful for illustrating thedistribution of habitats and providingdetailed biological information.

Key habitats of concern identified by thebiodiversity audit, can be ascribed to eachof the landscape character/natural areas.Programmes to conserve the biodiversity ofthese areas of Hampshire will need to takefull account of the detailed action andtargets set out in relevant habitat andspecies action plans.

URBAN - AN ADDITIONAL ‘CHARACTERAREA’

The three main landscape character/naturalarea classifications do not identify urban areasas a specific category. Yet in terms ofbiodiversity the character of these areas isquite distinct. Strategies and policies for urbanareas are also often distinct from those for thecountryside. It is therefore very important forthe Biodiversity Action Plan to address issuesthat are specific to urban areas.

An action plan for urban areas will beprepared along with those for other keyhabitats of conservation concern. This willcater for habitats particular to urban areas,and those also found within the countrysidebut with specific requirements because of theirurban location. A special emphasis of theaction plan will be to ensure sufficient accessto biodiversity for all who live in urban areas.

chapter 7chapter 4The audit of biodiversity described in theprevious section has enabled the selectionof habitats and species of priority concern.For each of the 21 key habitats identified, adetailed action plan is being prepared.

Action for most of the 444 priority specieswill be covered by relevant habitat actionplans. In some cases national species planswill guide action for priority species inHampshire. Where species cannot be easilyaccommodated by these plans, a specificspecies action plan will be prepared. Briefstatements will be prepared for each of the444 priority species, making the link withthe relevant action plan.

Volume 2 of the Biodiversity Action Planwill include all of the habitat action plans. Itwill also identify the relevant action planthat has been, or will be, prepared for eachpriority species, and include some speciesaction plans. More will be added as theybecome available.

Purpose and Scope of the Plans

The overall aim of each action plan is toenable successful conservation orrestoration of priority habitats and species.Each plan will provide an up-to-date andcomprehensive review of the current statusof these habitats and species, enablingeffective and well-directed action.

Each plan will have several goals:

• to provide information

• to establish comprehensive targets foraction

• to direct conservation action

• to raise awareness

• to provide a monitoring framework

Action plans will set the conservationdirection, outline priorities, and presentchallenges to the many organisations andsectors involved. Each will help individualorganisations to identify their role: forexample, site management, provision ofgrant-aid, site protection, or perhapsinfluencing national policy. Plans will give aclear picture of the extent and type ofaction required and the funds needed forimplementation.

The focus of each plan will be the actionrequired at a variety of levels, from the localneighbourhood to national policies andprogrammes. A complementary goal will beto ensure that action in Hampshire contributeseffectively to national objectives and targets.

Each plan should be seen as a workingdocument. The plans will provide areference point to monitor progress atregular intervals and will be updated overtime. Additional species may have plansprepared if the UK Action Plan recommendsthem or if dictated by local circumstances.

Content

Each habitat or species action plan will havethree main elements:

• Assessment - a summary of status,threats and action to date

• Objectives and Targets - detailedobjectives with measurable targets

• Action Points - actions required to meetobjectives and targets

Action plans will integrate all relevantprevious work, and provide acomprehensive assessment of conservationneeds. They will set out detailed objectives,and specific, measurable targets such as areaof habitat to be re-created or restored.Targets will be based on funding that mightbe reasonably available, and indeed actionplans may stimulate new resources. Actionwill be focused to reach targets at realisticyet ambitious timescales. Lack ofcomprehensive data will not be a barrier to setting targets, and indeed a target maybe the improvement of data quality.Targets will be audited and reviewed asfurther information and resources become available.

Each plan will follow a standard format,ensuring a consistent approach and level of detail. Action plans for Hampshire willalso be compatible with plans written forthe same habitats and species nationally,and liaison will be undertaken with anyneighbouring county preparing an action plan.

In striving to assimilate all pertinentinformation, action plans will integraterelevant proposals and approaches adoptedin other plans and strategies: examples areforestry strategies, Local EnvironmentAgency Plans, coastal management plans,local plans, regional planning guidance,landscape strategies, and projects such asthe Hampshire Heathland Project andWessex Coppice Group. In turn, the actionplans will help to refine, develop andimplement these other initiatives.chapter 4

Preparation of Action Plans

Each habitat or species action plan will beprepared by a working group or leadpartner. The opportunity is open to allpartners to be involved in the preparationof any plan. All plans will undergo wideconsultation to ensure that plans arecomprehensive, accurate, forward thinkingand widely supported.

Each group or lead partner preparing a planwill involve those with specialist knowledgeand those with a particular remit or abilityto influence implementation. Preparationwill also be guided by relevant nationalaction plans and the South-east RegionalAudit.

Implementation

Implementation of each action plan will beachieved through the HampshireBiodiversity Partnership acting collectively,individual partners taking action, or throughthe actions of others not yet involved. Theissues and types of action required will varywidely between plans. On the whole,success will be best achieved through eachpartner identifying the way in which theycan contribute. For example, the Ministryof Agriculture Fisheries and Food may wishto review the targeting of the CountrysideStewardship Scheme; a district council orAONB management committee may wishto identify land-use and management issueswithin a specific geographical area; orlandowners may wish to reviewmanagement objectives for theirlandholdings.

Nevertheless, encouragement or supportwill be needed to help some partners takeaction, or to focus efforts. Groups fromwithin the Partnership will be established tooversee and monitor plans. A lead agencywill be encouraged to overseeimplementation of each plan. This keyagency may be the organisation with themost direct influence on the particularhabitat or species, but not necessarily so.

Some issues and action may be commonacross plans. Awareness of commonobjectives and action will be needed toensure that action for one habitat or speciesis also targeted at other relevant habitats orspecies. For example, several differenthabitats would benefit from initiatives whichencourage grazing. Also, there may be caseswhere action for one habitat or speciesworks to the detriment of another habitator species. Such cases will need carefulreview.

Monitoring progress will be essential. Planswill be continually monitored, with a fullreview every five years. Plans will also needto be reviewed as circumstances and issueschange over time.

HABITAT AND SPECIES ACTIONPLANS: ACTION

• prepare action plans for 21 habitats

• prepare detailed action plans for individualpriority species where these are notcatered for by a national species actionplan or Hampshire habitat action plan

• establish working groups or lead partnersto prepare and promote theimplementation of the plans

• identify a lead agency to adopt eachhabitat and species action plan and takethe lead in monitoring, co-ordinating andencouraging action

• involve existing fora and projects indelivering action, for example the Farmingand Wildlife Advisory Group, HampshireWoodland Forum and HampshireHeathland Project

• establish partnership projects andinitiatives to help implement action

• encourage individual partners to identifyobjectives and action relevant to their ownactivities and integrate these, with specifictargeting and action, into their own workprogrammes

The collection of data on habitats andspecies is fundamental to the developmentand implementation of a local biodiversityaction plan. No single organisation has astatutory duty to collect biologicalinformation, yet the need to record andmonitor this is vital.

A large amount of data on the biodiversityof Hampshire is already available and muchof this is held on the Hampshire BiologicalRecord, housed at Hampshire CountyCouncil. However, there is still muchinformation to be obtained. There is also aneed to co-ordinate the various sets of dataheld by different organisations, to ensurethat the information is used most effectivelyto support the biodiversity programme.

The UK Biodiversity Steering Group Reportstresses the fundamental importance ofgood data and a co-ordinated approach toboth national data provision and local datamanagement. The Report recommends atwofold approach:

• development of a national biodiversitydatabase and information system

• development of a network of localrecord centres funded by localconsortiums, to service data needs atthe local level and support and exchangeinformation with the national system

LOCAL RECORD CENTRES:A CHALLENGESET BY THE UK STEERING GROUP

The UK Biodiversity Steering Group Reportsuggests that local data management is bestcarried out by local biological record centres.Local centres are needed to both serve localneeds and contribute information at thenational level. The Report recommends thateach centre should be developed andmanaged by a consortium of localorganisations, and have the following functions:

• to act as a focus for biological recordmanagement in the area

• to manage the collection, validation andmaintenance of key data sets on behalf ofpartners

• to act as a contact point for access to databy local and national users

• to provide support and guidance torecorders, local societies and recordingschemes

• to provide support for the local planningprocess

• to promote and steer future survey

• to provide data and an information serviceto a range of organisations and individuals

The consortium-led approach has manybenefits: managing partners will have a senseof ownership of the centre; costs of the dataservice are shared between a number oforganisations; there is less duplication ofrecords; and it is easier to standardise andquality control the collection, validation andmanagement of the data.

INFORMATION AND DATA

Data underpins the entire biodiversity programme. A large amount of data is already available on

the Hampshire Biological Record, but this could be improved. The development of a Hampshire

Biological Record Centre is a priority concern.

A group of national organisations isdeveloping a ‘National Biodiversity Network’, aproject which includes both establishing thenational data system and network of localcentres. Centres are likely to operate at thecounty scale and will be developed wherethere is a local partnership committed to theirdevelopment.

The Hampshire Biological Record

Hampshire County Council has, for manyyears, acted as a central repository for muchhabitat and species data, and has a computerdatabase and staff dedicated to the collection,maintenance and supply of biological data.

There are almost 5,000 detailed site recordsand 300,000 species records on the BiologicalRecord database. This covers about 34,000 haor 9% of Hampshire and currently excludesthe 8% of the county contained within theNew Forest. Best estimates are that detailedhabitat records of another 3 to 8% ofHampshire are required to cover most siteslikely to prove of particular natureconservation significance. Although largeamounts of data on habitats is standardisedand accessible on the Biological Record, muchof the information on species other thanplants is not. The collection of additionalinformation on both habitat and species is ahigh priority for refining the audit for theBiodiversity Action Plan.

Although the Biological Record is incomplete,lack of data should not delay the Action Planprocess. The best available data will be used,and at the same time, improving theinformation base will be given high priority.Upgrading the collection, organisation and co-ordination of all biological information willenable the establishment of a solid baselinefor all Hampshire’s habitats and species ofconservation concern. Regular and systematicrecording will also be needed to detectchange and measure progress in achievingbiodiversity targets.

Data collection through ground survey islargely undertaken by the HampshireHabitat Survey Project. Approximately 250sites, or an area of about 3,500 ha, arecovered each year. The two person surveyteam is based with the Hampshire WildlifeTrust and is funded by the County Council,English Nature, the Environment Agencyand several district councils.

Habitat Map for Hampshire

Hampshire County Council recentlycommissioned a new set of aerialphotographs of the county. From this, amap which shows the distribution ofhabitats and land-use has been produced indigital form for display on computer. Themapping is very comprehensive. Every landparcel has been assigned one of 81habitat/land-use classes, and all hedgerowslonger than 100m are also mapped. Thismapping will be invaluable for identifying thedistribution and extent of habitats.

The full nature conservation quality of someland cannot be determined byinterpretation of aerial photographs. Forexample it is difficult to differentiatebetween grassland that is herb-rich and thatwhich has been agriculturally improved. Inthese cases, the mapping will assist thefocusing of ground survey which, in turn,will be used to refine the mapping.Thiscomprehensive mapping provides for thefirst time the opportunity to accuratelymonitor land-use and habitat change.

Towards a Record Centre

The existing Hampshire Biological Record,the Hampshire Biodiversity Partnership, andthe Habitat Survey Project, together withpotential assistance from the NationalBiodiversity Network project, provide theingredients for the development of a countyrecord centre. This would become part ofthe National Biodiversity Network. Arecord centre would capitalise on the dataand information systems already availableand ensure the full complement of servicesrequired to support the Partnership andthe biodiversity programme.

GENERAL ISSUES AFFECTING

BIODIVERSITYMany land-uses and land management activities have a considerable effect on biodiversity.Agriculture and development have a particularly strong influence, but others are also significant inHampshire. Strategies and courses of action are required to address the major issues affecting biodiversity.

54

The conservation of biodiversity is not onlydependent on direct action for habitats andspecies. There are many wider issues thathave a great influence on the welfare ofwild plants and animals. Two of the keyissues in Hampshire are agriculture anddevelopment. Many other human activities,such as various uses of the land, patterns ofresource consumption, energy use andtransport, also have very considerableimpact. Each of these issues is brieflyreviewed. It is not intended to includedetailed proposals for action here, butrather to make the connection betweenbiodiversity conservation and otheractivities.

The principal organisations and agenciesthat have a particular remit for land-use andland management activities are involved inthe Hampshire Biodiversity Partnership.Each organisation should develop their ownawareness and understanding of how thevarious issues affect biodiversity, and chart acourse of appropriate action.

There are many different levels of actionrequired and many different vehicles forpursuing action, for example the integrationof biodiversity objectives into plans andstrategies such as Local EnvironmentAgency Plans, or capitalising on existingstudies or programmes such as TheHampshire Farming Study7. The HampshireBiodiversity Partnership will encourage andsupport organisations in the formulation oftheir action for biodiversity. Whereconsidered appropriate, the Partnership willestablish topic groups to consider individualissues. These will develop proposals andagree the action needed to achievebiodiversity goals.

AGRICULTURE

Approximately 60% of Hampshire is usedfor agriculture. Farming plays a pivotal rolein determining the biodiversity of thecountryside and traditional unintensivefarming practices are particularly importantin maintaining wildlife habitats.

Many different types of habitat occur onfarmland, including wildflower meadows,ponds, and hedges. Stubble, field marginsand fallow are also valuable for wintering,feeding and breeding birds. Less directlyassociated with the agricultural enterpriseare the many woodlands within the farmedlandscape.

General Issues Affecting Biodiversity

Habitat Loss and Change

Many habitats have suffered enormouslosses, particularly over the last 50 years.Changes in farming practices since theSecond World War - towards greaterintensification and specialisation away frommixed farming systems - have resulted inmajor losses and fragmentation of habitat.

These changes have resulted from a nationaland European policy framework initiallydeveloped to meet the urgent need toproduce more home-grown food. Thepolicies have encouraged food productionwithout commensurate support for theconservation of biodiversity and protectionof the landscape. They were drawn upwhen Europe faced the serious risk of foodshortage. Although not wrong at the time,the policies have remained unchecked fortoo long and have only recently begun tobe reformed. Food production remainsvery important, but needs to be balancedwith environmental objectives.

Many of the habitats which remain havesuffered degradation through drainage,nutrient enrichment, heavy grazing, re-seeding,the application of pesticides or herbicidesand the lack of traditional management.Many farmers are aware of the effects ofthese practices on biodiversity. Some areturning to alternative approaches such asintegrated crop management.

Incentives for Land Management

In recent years, the balance betweenagricultural production and conservation ofbiodiversity has been encouraged by theintroduction of environmental landmanagement schemes. These use financialincentives to encourage farming practicesmore sympathetic to wildlife and includethe Countryside Stewardship andEnvironmentally Sensitive Area schemesadministered by MAFF, and the WildlifeEnhancement scheme administered byEnglish Nature.

Some aspects of environmental or otherland management schemes such as set-aside, have been too inflexible. Currentpolicy directives tend to allow greaterdiscretion in the implementation of theseschemes, maximising the benefits to wildlife.All of these schemes are vital to supportthe Biodiversity Action Plan.

Funding is of course limited, and much goodenvironmental management is reliant on thewillingness and financial resources of landmanagers.

Green consumerism could prove anincentive for environmental landmanagement. Encouraging local markets tobuy produce from environmentally-managedland-holdings could bring benefits to bothfarmers and biodiversity.

Advice on Land Management

Advice to landowners on land managementfor biodiversity is very important. While theCountry Landowners Association (CLA) andNational Farmers Union (NFU) are active inpromoting environmentally sensitive farming,the availability of on-the-ground advice fromadvisors with a strong agricultural andenvironmental background is essential.

English Nature have an advisory role onSSSIs, and advice is also available from thoseadministering MAFF incentive schemes.However, advice should be more widelyavailable. The recent appointment of aFarming and Wildlife Advisory Group officerfor Hampshire will greatly assist. Organisationsin Hampshire are also exploring ways toimprove support and advice for the ownersof the locally designated Sites of Importancefor Nature Conservation.

Common Agricultural Policy (CAP)

Incentive schemes and advice, and thegoodwill and sense of stewardship towardsthe environment by landowners, are allimportant. However, the primarydeterminant of the future of biodiversitywithin agriculture is the Common AgriculturalPolicy (CAP). Related aspects are consumerdemand, social trends and employmentwithin the countryside, policies promotingdiversification of enterprise within thecountryside, and development in technology.

The original aims of the CAP were toincrease agricultural productivity, ensure afair standard of living for the agriculturalcommunity, stabilise agricultural markets,guarantee regular supplies of food andensure reasonable prices to consumers.The Policy has been very successful in theseaims but is now due for review. The CAPsupports farming which is insensitive tobiodiversity, and this is at odds with thenational rise in awareness, demand andpolicy for conservation.

Biodiveristy Action Plan for Hampshire

56

The CAP and national policy on biodiversitygive conflicting messages, and this is a sourceof frustration for many landowners.

In 1997 the European Commission publishedAgenda 2000, a blueprint for the developmentof certain European Union policies includingthe CAP. The Commission suggest that CAPreform should be accompanied by measures todiversify rural economies, maintain socialstability and conserve and enhance theenvironment. Reform of the CAP may result inremoval of support for farm product pricesover time. The issues involved are complex,but one goal will be to integrateenvironmental objectives into the CAP.Hopefully reform will result in a re-invigoratedagri-environmental policy, with new andextended agri-environment instruments.

The Hampshire Farming Study has helpedinitiate strong representation to national andEuropean government on the subject of CAPreform and integrated rural development.Much of the future for agriculture and theenvironment lies with reform of the CAP, andin Hampshire it is important to make the bestof any opportunities arising from this.

A Range of Activity

Conserving biodiversity within the agriculturalsector is a particular challenge and one thatinvolves a wide partnership, from delivery ofnational and local incentive schemes andadvice, to forecasting change and influencingpolicy. Particularly influential in the latter willbe the NFU and CLA.

The aim of the Biodiversity Action Plan forHampshire will be to influence this range ofactivity. Action stemming from the Plan willhave to be clearly relevant to the landownerswho manage a large proportion of ourcountryside.

DEVELOPMENT

Development has caused extensive loss ofwildlife habitat, particularly within the last 50years. Housing, industrial and businessdevelopment, roads, coastal development,waste disposal and mineral extraction havebeen especially significant. This has resultednot only in direct loss of habitats, but also awhole variety of indirect impacts on natureconservation such as pollution, modificationof water quality and flow, disturbance tosites in proximity to development, andisolation and fragmentation of habitat. Thedemand for new development continuesand this should be accommodated whilemaintaining the quality of the environment.

Sustainable Development

The Government published both SustainableDevelopment: The UK Strategy8 andBiodiversity: The UK Action Plan in 1994.These strategies for development andbiodiversity are intimately linked.

Sustainable development ‘seeks to improvethe quality of human life without underminingthe quality of the environment’. In carryingout sustainable development, habitats andfeatures that are effectively irreplaceableshould not be destroyed, since once lostthey are lost forever. The concept ofsustainable development embodies theprinciples of not only preventing destructionor damage, but also taking the opportunityto enhance biodiversity. Also important isthe adoption of the precautionary principle:if in doubt about the environmental effectsof the development, avoid the development.

The European Directive on EnvironmentalAssessment (85/337) has greatly influencedEnvironmental Impact Assessment in the UK.However, some aspects of the Directive havenot yet been translated into UK legislation.Changes in legislation and procedures withinthe UK will be required to fully achieve theaim of sustainable development.

Land-use Planning

For development to be sustainable in termsof biodiversity, it should be well-planned andcontrolled. Several pieces of national andEuropean legislation and nationalgovernment guidance support biodiversityobjectives, including the Wildlife andCountryside Act 1981 and amendments1985, the Habitat Regulations 1994, andPlanning Policy Guidance Note 9: NatureConservation 1995 (PPG9).

To maintain and enhance biodiversity at thelocal level, the Hampshire County StructurePlan and local plans should be based ondetailed audits of the nature conservationresource, and the capacity of the areaconcerned to accommodate development.Policies within these plans need to addressthe protection of designated sites of natureconservation importance, conservation ofbiodiversity in the wider countryside, andthe enhancement of biodiversity withindevelopment. Planning Policy GuidanceNote 12: Development Plans and RegionalPolicy Guidance 1992 (PPG 12) requiresplanning authorities to conductenvironmental appraisals of theirdevelopment plans to make clear theimplications of various strategy and policyalternatives. These approaches need to fullyinclude implications for biodiversity.

Levels of development expected byGovernment to be accommodated inHampshire are set out in Regional PlanningGuidance. Regional Guidance needs to besensitive to the biodiversity resource ofHampshire and the other counties in thesouth-east.

A disciplined approach is required to assessthe effects of development proposals.Decision makers should be sufficiently welladvised as to what makes a goodenvironmental assessment and what theopportunities are for conserving orenhancing biodiversity. Factors to considerinclude avoiding damage, mitigation ofimpacts, compensatory measures,enhancement, restoration, landscaping andmanagement. Conditions and agreementsattached to planning permissions will helpto secure these measures.

FORESTRY

Forestry is a major land use which has agreat effect on biodiversity. Broadleavedwoodlands throughout England havesuffered from lack of management fordecades due to changing markets and thereduced economic viability of woodlandproducts. Replacement of nativebroadleaved woodland with conifers, andthe cessation of traditional forms ofmanagement such as coppicing andpollarding, have all led to a reduction inbiodiversity.

Circumstances are changing, particularlywith the provision of grant-aid, thoughsustainable management of ancient semi-natural woodland is still an issue.

The Government has set out its approachto sustainable forestry in the UK ForestryStandard 1998. This provides a frameworkfor protecting and managing woodland inthe future and gives specific attention tobiodiversity issues.

In 1996 the Forestry Authority introducedWoodland Improvement Grants, under itsWoodland Grant Scheme, specificallytargeting biodiversity conservation. Grantsare available for undermanaged woods,including funding for the restoration ofcoppice and for woodland biodiversity, andalso under a special project ‘Coppice forButterflies’. This new targeted approach togrants by the Forestry Authority will greatlyassist biodiversity conservation.

For many years Hampshire County Councilhas been providing grant-aid for therestoration of derelict hazel coppice, giving anew lease of life to many ancient semi-natural woodlands. A healthy coppiceindustry is dependent upon the availabilityof workable coppice, the demand forcoppice products, and a skilled coppiceworkforce. Grant-aid has beencomplemented by the establishment of theWessex Coppice Group - an innovativeproject which is encouraging economicgrowth in the hazel coppice industry, mainlythrough marketing of coppice products andthe training of coppice craftsmen.

COASTAL ISSUES

The coastline of Hampshire supports a richassemblage of plants and animals. Intertidalmudflats and marshes are particularlyvaluable: they provide feeding grounds forlarge numbers of birds and many areas areof international importance. Other habitatsinclude grazing marsh, lagoons, shingle spitand beaches. Nevertheless, the coast issuffering from pressures that threaten thiswildlife interest, including port and leisuredevelopment and channel dredging.

Sea level rise due to global warming alsoputs pressure on the coast.Within theSolent, a significant loss of intertidal habitatsis predicted as they are ‘squeezed’ betweenrising sea levels and coastal defences. A sealevel rise of 6mm per year along the coastof Hampshire is predicted, giving a 32cmincrease by 2050. The amenity value of thecoast introduces further pressures fromrecreation and tourism. Pollution is also aproblem, and includes organic enrichmentfrom sewage and agricultural run-off.

Estuary and shoreline managementstrategies should fully embrace biodiversityobjectives. Many of the issues and actionrequired are set out in Strategic Guidance forthe Solent9, and these will be included incoastal habitat action plans.

RECREATION AND TOURISM

Countryside recreation is an increasinglyimportant trend. Most visits to thecountryside are less than a five mile round-trip from home, so access to recreationnear to where people live is particularlysignificant. Appropriate access to naturereserves and other wildlife areas isconsistent with conservation of biodiversity.Access helps to increase publicunderstanding of nature, thus making acontribution to biodiversity protection.

Nevertheless visitor pressures can bedetrimental, especially at heavily used sites.Sensitive species and habitats may bedamaged, and noisy, disruptive and damagingactivities should be prevented or verycarefully controlled. Ancient woodlands,fens, heathlands and coastal habitats areparticularly vulnerable. Appropriatemeasures will be included in habitat actionplans.

Visiting the countryside is one of Britain’smost popular leisure activities. Concern forbiodiversity could be promoted as a centraltheme in all countryside recreation andtourism initiatives. If people are moreaware of the needs of the plants andanimals that they enjoy seeing in thecountryside, this will help to achievebiodiversity objectives.

WATER MANAGEMENT

The use of water affects biodiversity in anumber of ways. Problems of climatechange, inappropriate site management andabstraction can all lead to rivers, lakes andwetlands being severely depleted. Wetlandhabitats and the wildlife which dependsupon them can be seriously affected by lackof water and the reduction in quality ofremaining supplies. Inappropriate watercourse management and surface drainagecan reduce the naturalness, variety andextent of wildlife habitat along watercourses.

The other main concern for wetlandbiodiversity is pollution. Effluent fromsewage treatment works and industrialprocesses and run-off from farmland, maygo directly into water courses or seep intogroundwater. High nitrate and pesticideconcentrations and low dissolved oxygenlevels are some of the resulting problems.Many animals and plants which depend onclean water cannot tolerate theseconditions.

Continual provision of new water resourcesis unsustainable and the demand for waterneeds to be managed. The requirement tobuild many more homes in Hampshire by2011 will have major water resourceimplications.

ENERGY

The production, transmission and use ofenergy have wide-ranging effects onbiodiversity. The generation of energyrequires large installations such as powerstations, transmission lines, or pipelineswhich affect biodiversity directly throughland-take. It is important that theseinstallations are sited sensitively, away fromvulnerable wildlife habitats.

The burning of fossil fuels results in bothacid deposition and the release of pollutantssuch as carbon dioxide into theatmosphere. Acid rain affects a variety ofhabitats, particularly forests and lakes.However the release of carbon dioxide ishaving a more widespread effect. Emissionsof greenhouse gases by burning fossil fuelshas now been positively linked with globalwarming.

This will result in very significant implicationsfor biodiversity. A sustainable energy policy,which reduces energy demand andincreases the use of renewable resourcessuch as solar power and biomass fuels,should be promoted.

TRANSPORT

Transport has both a direct and indirectimpact on biodiversity. The growth of roadtransport is particularly significant: roadconstruction can damage, fragment or resultin the complete loss of habitats, and alsocreate barriers to species movement.Extraction from gravel pits and quarries foraggregates and development adjacent toroads also affects wildlife.

Car travel has increased dramatically inrecent decades and is forecast to continuegrowing at an alarming rate. Upgrading ofthe road network will significantly affectwildlife and it is important to ensure thateach project does not affect importanthabitats. Public transport needs to becomea more attractive alternative to private caruse, alongside walking and cycling for shortdistance travel. The maintenance andimprovement of the existing transportinfrastructure should take priority over thedevelopment of new routes.

AIR QUALITY

Transport and energy production releasepollutants into the air, and many industriesalso contribute to low air quality. Airpollution has well documented effects onpeople’s health, but less well known are theimplications for biodiversity.

Air pollution has both local and widespreadeffects. Acid deposition can result inacidification of soils and water bodies, andrelease of chemicals such as sulphurs andnitrates can also affect organisms.Biodiversity particularly at risk from poor airquality includes sensitive species such aslichens, habitats naturally low in nutrients,and habitats on acid soils or in acid waters.

CLIMATE CHANGE

Emissions of greenhouse gases worldwideare contributing significantly to globalwarming. Small changes in the earth’stemperature will have great effects onbiodiversity. Some of the predicted changesinclude a rise in sea levels and a generalwarming of temperate regions. Thesechanges will result in shifts in thecomposition of aquatic and terrestrialcommunities, and changes in wildlifebehaviour and habitats.

Local strategies for biodiversity need to takeserious account of this issue. Sea level riseis a considerable threat in Hampshire. Theproblems and opportunities that this posesneed to be anticipated and planned for.Coastal habitats will be lost and species onthe edge of their range may disappear.Climate change illustrates that a long-termperspective for biodiversity needs to betaken in the preparation of action plans.

GENERAL ISSUES: ACTION

• encourage organisations and individualswith a particular responsibility for land-useand land management activities such asagriculture, development, forestry andwater resources, to establish their ownobjectives and action for biodiversity,taking particular account of targets andaction outlined in habitat and speciesaction plans

• establish groups where appropriate toreview issues influencing biodiversity andprepare plans of action

• develop action for biodiversity throughappropriate land-use fora and initiativessuch as SERPLAN and the Solent Forum

• take full account of biodiversity objectiveswithin land-use plans and strategies suchas the Hampshire County Structure Plan,local plans and Local Environment Agency Plans

• influence local and regional policy andnational guidance, policy and legislation to support biodiversity objectives in Hampshire

Biodiversity conservation cannot just be leftto people involved in land management andnature conservation. It involves manysectors of society and people in all walks oflife. Although many people are aware ofthe need to conserve biodiversity, they donot always appreciate that it concerns themdirectly: their actions can make a difference.

An action plan will be prepared tospecifically address awareness andinvolvement issues. A working group willassess current initiatives and theireffectiveness, identify gaps, and agreeobjectives, targets and appropriate action.The group will fully consider methods ofspreading the biodiversity message. Someinitial ideas are sketched out here.

Key Sectors

One of the central aims of the BiodiversityAction Plan is to increase understanding andsupport for biodiversity throughout thecounty. This will involve key sectors ofsociety: farmers and land managers, alllevels of government, business and industry,media and education, youth and communitygroups and the professions. Successfulimplementation of the action plan willdepend on widespread understanding.

Biodiversity messages and initiatives can begeared to the particular interests of eachsector. For instance, the success of thebiodiversity programme is very dependentupon action by farmers. Farm managersand industry will be keen to know how topromote biodiversity without losing long-term profitability. Youth leaders may wish toknow how to interest young people in thenatural world, and in education, schoolsneed to be aware of all the opportunitiesfor integrating biodiversity into thecurriculum.

Getting the biodiversity message across willinvolve guidance from the HampshireBiodiversity Partnership and the support ofpeople in each sector who cancommunicate in terms that are bothrelevant and understandable to the sectorconcerned. Leaders in each sector shouldbe invited to take an active role.

The Public’s Role

Messages on biodiversity should reacheveryone as individuals too. Here, messagesshould focus on the benefit of biodiversityconservation to us all: the enjoyment ofcontact with nature; the need to protectwildlife for our children; and our moral dutyto protect wild species. Action forbiodiversity will improve the quality ofeveryone’s life in their own neighbourhoodsand communities.

Building awareness can be done in manyways. Information can be distributedthrough a variety of media and materialssuch as publications, illustrated talks, displaysin shopping centres and libraries, guidednature walks, adverts or programmes onradio and television, the internet andmarketing of biodiversity alongside popularproducts. Messages need to be simple,relevant and easily accessible.

People can also be given opportunities toplay a more active part: improving theirown gardens for wildlife; helping to clear thevillage pond of debris; setting up a wildlifecorner in their local park; and celebratinglocal plants and animals in festivals andother events. These types of initiatives givepeople a greater understanding and a stakein the well-being of their local biodiversity.Direct experience builds appreciation ofbiodiversity conservation.

AWARENESS AND INVOLVEMENT

People in all sectors of society should play their part in conserving biodiversity. Ultimately,

successful implementation of the Biodiversity Action Plan will depend on this widespread

understanding.The Hampshire Biodiversity Partnership will develop a programme to increase

awareness and involvement in biodiversity conservation.

Education and Training

Integrating biodiversity conservation intoformal education is one of the mostimportant vehicles for raising awareness.Young people form their attitudes to theenvironment at a very early age, and ifchildren understand and respect nature theyare more likely to grow intoenvironmentally-aware adults. Education ofschool children can also have an importantknock-on effect to parents and the widercommunity.

Several national initiatives are examininghow biodiversity can be better integratedinto the National Curriculum and teachertraining. On a practical level, biodiversityeducation can be promoted throughensuring that all schools have access tonature areas, preferably within their ownschool grounds. Hampshire CountyCouncil’s Schools Landscape Project and thenational organisation Learning ThroughLandscapes are two of the many groupsthat advise on ways to enrich schoolgrounds.

Other initiatives could help to spreadawareness. Visitor centres provide a focusfor practical activities and field studies, offerequipment and teaching materials, houseexhibitions and libraries of information.Nature reserves in the community givepeople access to wildlife at first hand.Projects which promote a rich biodiversityin the neighbourhood are vitally importantin every community, rural or urban.

Co-ordinated Programme

Widespread understanding is crucial forsuccessful implementation of theBiodiversity Action Plan. Action must beunderpinned by greater public awarenessand support, and a heightened awarenesswithin those sectors that can have aninfluence on biodiversity conservation.Many excellent initiatives already exist: forexample, the Hampshire Wildlife Trust’sParish Tree Wardens Scheme, LocalEnvironment Initiative and WATCH projectfor children; district council initiatives such asEastleigh Borough Council’s Pond RescueCampaign and Southampton City Council’sHawthorn Urban Wildlife Centre; andHampshire County Council’s Community

Action Fund and Country Parks. Howevera strategy is needed to co-ordinate efforts,identify gaps, and greatly increase popularsupport.

A marketing strategy should aim to get thekey messages of biodiversity conservationacross to both the general public and to keysectors. Leaders in society will be neededto champion the cause, and more examplesof good practice will be needed to illustratewhat can be accomplished. Biodiversityshould become a household word and anissue that transcends all levels of society.

AWARENESS AND INVOLVEMENT:ACTION

• establish a working group to prepare anaction plan to address awareness andinvolvement in biodiversity conservation

• ensure that information on biodiversity andhow to get involved in conservingbiodiversity is readily available to thepublic. Local authorities and voluntaryconservation organisations in particularcan promote awareness and provideopportunities for involvement throughmechanisms such as grant-aid forcommunity projects and the managementof nature reserves

• promote the Biodiversity Action Plan forHampshire and publicise the mainobjectives and programme of action

• develop a strategy for marketingbiodiversity which targets key sectors suchas business and industry, all levels ofgovernment, the public, land managers and education

• encourage and support organisations indeveloping their corporate awareness andcommitment to biodiversity, for examplewithin all departments of local government

• ensure that biodiversity is a centralcomponent of Local Agenda 21programmes and that Agenda 21 initiativeshelp to generate awareness andinvolvement in biodiversity

• support the integration of biodiversityconservation into formal education

The Hampshire Biodiversity Partnership iscommitted to working together to progressbiodiversity conservation. The Partnershipwould like to integrate all interested partiesto progress the action set out in this Plan.

The Partnership has a long-term vision forthe biodiversity programme. Progressingaction will involve a great variety of projects,initiatives, courses of action and levels ofactivity. Some can be progressedimmediately, others will evolve over time.The process needs to be adaptable tochanging circumstances. The Partnership iscommitted to a long-term association, onethat will monitor and review progress wellinto the next Millennium. This will requireconsiderable co-ordination to ensure thatwe remain focused and stay on course todeliver action and meet the targets whichwe set for ourselves.

WAY FORWARD: ACTION

• develop and maintain a long-termPartnership to progress the conservationand enhancement of biodiversity inHampshire through developing initiatives,exchanging information, encouragingaction, and monitoring and reviewingprogress. This work will be assisted by theSteering Group of the HampshireBiodiversity Partnership.

• encourage individual partners to reviewtheir own action, to help meet theobjectives and targets set out in theBiodiversity Action Plan and associatedhabitat and species action plans

• monitor the development of the UKBiodiversity Programme and other policiesand initiatives at the national andinternational level, for integration into theBiodiversity Action Plan for Hampshire

• review and update the Biodiversity ActionPlan, including the habitat and speciesaction plans, every five years

THE WAY FORWARD

The Biodiversity Action Plan marks the beginning of a co-ordinated programme of action. Each

individual and organisation concerned with the conservation of Hampshire’s biodiversity has a

fundamental role to ensure the success of the objectives of the Plan.

ANNEX 1 - IDENTIFICATION OF PRIORITY SPECIES IN HAMPSHIRE

The following criteria have been used for selecting priority species from the list of 776 speciesof concern in Hampshire:

• national priority species occurring in Hampshire

• other species if:

• the UK distribution is restricted to Hampshire, or Hampshire has the national stronghold, or Hampshire has a regionally important population, or

• they are suffering a rapid decline, or

• all of the following 4 criteria can be met: isolated, decline, rare, high degree of threat

Definition of terms:

Significance

Restricted to Hampshire Hampshire holds 100% of the UK population

National stronghold Hampshire holds over 10% of the UK population, or one of 3 counties or fewer with the species

Regionally important SE England a stronghold for the species; Hampshire has a strong population in the region

Widespread Species has widespread distribution in UK and in Hampshire

Isolated Local population is isolated from other populations; likely to contribute to genetic diversity of species

Decline *

Rapid decline 50-100% decline over last 25 years

Decline 6-49% decline over last 25 years

Stable no more than 5% decline over last 25 years

Increasing generally considered to be increasing

* Decline figures reflect the local situation if known, but often the national figures are taken.It is thus assumed that national declines are also occurring in Hampshire.

Local Rarity

Rare currently occurs in 1% or fewer tetrads **

Scarce currently occurs in 5% or fewer tetrads

Uncommon currently occurs in 6-20% of tetrads

Common currently occurs in more than 20% of tetrads

** a tetrad consists of 4 square kilometres - i.e. 2 km x 2 km

Local Threat

high high degree of threat

medium medium degree of threat

low low degree of threat

Hampshire is one of the richest areas for wildlife in England. TheBiodiversity Action Plan for Hampshire is an exciting new approach tomaintaining and enhancing the county’s natural assets.

The Hampshire Biodiversity Partnership embraces a wide range oforganisations all working together for nature conservation. ThePartnership has written the Biodiversity Action Plan to review thestatus of all habitats and species in Hampshire and set out a frameworkfor action. For the first time, detailed targets will be set andconservation action will be co-ordinated and monitored.

The Biodiversity Action Plan for Hampshire:

• describes Hampshire’s biodiversity

• identifies habitats and species of priority concern

• explains how detailed action plans will be prepared

• reviews important issues that affect biodiversity in Hampshire

• promotes a strategy for managing information and data

• sets out action for raising awareness of biodiversity

It is essential reading for anyone concerned about nature in thecountryside or urban areas, and all those involved in planning andmanaging the future of Hampshire’s biodiversity.
