Heathland and Acid Grassland or Woodland within the Buckinghamshire and Milton Keynes

Bio-diversity Action Plan (BAP).

U4 Grassland – a habitat composed of a mixture of grasses and herbs which exists on

acidic soils or substrates. This grassland type is increasingly rare within the Chilterns

and is diminishing as methods of land management have changed away from regular

grazing or mowing.

W10 Woodland – a habitat composed of oak woodland predominantly on acid soils

or substrates. Typical species, in the Moorend Common SSSI, include pedunculate

oak and silver birch, an understorey of hazel and hawthorn and a ground flora of

bracken and bramble.

W14 Woodland – a habitat composed of beech woodland on relatively base poor to

acidic soils and substrates. Typical species, in the Moor Copse, include beech and an

understorey of holly and bramble with a sparse ground flora owing to the dense

shade created by the mature beech canopy.

Detailed ecological information can be found within the ‘Heathland’ and ‘Woodland Habitat’

sections of the Buckinghamshire and Milton Keynes BAP of 2000 and the Chilterns

Conservation Board’s draft BAP of 2006. (LEPC & MCCC - Surveys Brief 2012-2015/1st draft

2012).

Objectives

The survey formed part of the Heritage Lottery funded Chilterns Commons Project managed by the

Chilterns Conservation Board. The work was part of a larger project which included historical

research and ecological studies alongside monitoring conservation practices to determine their

effectiveness.

The Lane End Parish Council and the Moorend Common Conservation Committee produced a

Management Plan in 2012 and within it there is mention of survey work being carried out on

butterflies, moths and aquatic macro invertebrates (LEPC & MCCC - Surveys Brief 2012-2015/1st

draft 2012). Survey work on other invertebrate groups was planned in 2010 but did not actually

occur. The survey reported in this document was designed to address this omission in covering

invertebrate groups where little or no records existed.

Survey Methodology

4 locations for siting pitfall traps were identified and established on 13 May 2013. Each location

comprised 4 separate pitfall traps set at corners of a square metre and it was agreed with the

volunteer team that traps would be emptied and reset approximately every 2 weeks through the

summer to finish around the beginning of September. For each location captures from the 4 traps

would be treated together but divided into separate containers of (1) spiders & harvestmen,

(2) beetles, (3) woodlice, centipedes & millipedes and (4) other miscellaneous captures.

The 4 locations were chosen to represent different habitats and locations within the Moor End

Common site as a whole and were sited as follows (see Maps 1 & 2 ):

Site A – SU 80179056 – Just off the edge of the northern section of Middle Meadow amongst leaf

litter under mature oak

Site B – SU 80219049 – Open area of wet grassland within compartment F

Site C – SU 80099075 – Open grassland within North meadow

Site D – SU 79969062 – Amongst mature oaks adjacent to stream on N edge of compartment B

In addition to the pitfall trapping programme a number of yellow pan traps to capture flying insects

was supplied to the volunteer team to set up on site when pitfall traps were being emptied and

reset. As it turned out, time availability of the volunteer team made the setting and collection of

pan traps impractical and none were set by the volunteers. Just one pan trap was set on a collecting

visit made on 13 May 2013.

Invertebrates Recorded

Spiders

60 species of spider were recorded during the survey period. As well as the pitfall samples, other

surveys were carried out on 18.10.12, 13.5.13, 5.8.13 and 18.9.13 - these consisted primarily of

suction sampling sessions with some sweeping of low vegetation and beating of gorse and lower

branches of oak. The pitfall samples were, surprisingly, not very productive for spiders and

harvestmen. During pitfall sampling at Chimney Meadows Reserve in Oxfordshire between 2005

and 2010 the traps yielded considerably more individual spider specimens with the total number of

species being e.g. 57 species recorded from 103 sample sets in 2009. At Moorend, even though the

total number of species recorded was similar in 2013 (to that for Chimney Meadows quoted above),

over half of these records came from collecting methods other than pitfall sampling. It is difficult to

explain why the pitfall traps captured such a low number of arachnids. In conversation with other

arachnologists they too had experienced low numbers of arachnids in pitfall surveys they had

conducted in 2013. Possible reasons for the low numbers were the very cool temperatures

recorded throughout the spring and early summer of 2013. One of the predominant spider families

collected from pitfall traps is the Lycosidae. These ground moving wolf spiders tend to reach

maturity in the late spring and early summer and cooler than average temperatures during this

period may well compromise the successful maturing of young spiders into mature adults.

Amongst the spiders recorded the following species is of interest:

• The jumping spider Marpissa muscosa. National Status ‘Notable B’: uncommon in Great

Britain and thought to occur in between 31 and 100 10km squares of the National Grid.

Collected from underneath the bark of a fallen branch in compartment G/South Meadow. The

species is recorded throughout south-eastern England with a few scattered records further

9

west and north. In Dorset it is common under flat stones on the tops of dry stone walls but

elsewhere it occurs mostly underneath loose bark on trees, on posts and paling fences.

Many specimens collected using the suction sampler were immature and therefore impossible to

identify down to species (apart from a very few instances of immature specimens having distinctive

markings enabling identification to species). These unidentified immatures indicate a richer spider

fauna for Moorend which, if further funding were available, could be surveyed in the future.

Beetles

41 species of beetle were recorded from the pitfall traps. Of these 22 were ground beetles and in

terms of numbers of individual beetles collected were by far the most dominant group. The three

commonest species were Pterostichus madidus with 393 specimens, Abax parallelepipedus with

241 specimens and Carabus problematicus with 116 specimens. Of particular interest was the green

and bronze ground beetle Agonum sexpunctatum. The national status for this species is ‘Notable A’

- uncommon in Great Britain and thought to occur in 30 or fewer 10km squares of the National

Grid. The preferred habitat for this species is ‘On damp open ground near water, on sandy soils in

heaths and open woodland’ (Luff 2007) which corresponds well with the location of site B – the

only pitfall trap site where it was found. This record caused some excitement when it was identified

by Lloyd Garvey at the University Natural History Museum in Oxford where Lloyd was identifying

the beetles.

Unfortunately, due to prolonged immersion in the propylene glycol solution many of the beetles

began to disintegrate and so preserving specimens was not possible. Lloyd did a great job in

identifying the material and only had problems distinguishing between 2 very similar species. The

entry in the species list for Pterostichus nigrita/rhaeticus is the one record where it was impossible

to distinguish between the 2 species – they are only separable by examination of the genitalia and

the fragmented state of the specimens made this impossible.

Centipedes, Millipedes and Woodlice

All but one of the centipede and millipede species recorded from the pitfall traps have the national

status of ‘Common’. The exception, the stone centipede Lithobius muticus, has a national status of

Notable B and is regarded as scarce nationally. In the Chilterns, however, it is a locally common

species, Moorend providing a suitable deciduous woodland habitat.

Five species of woodlice were recorded. The Carr Slater Ligidium hypnorum is locally common in the

Chilterns but is nationally only found in the south east and south central regions - not being

recorded north of a line between the Wash and the Bristol Channel. The other species are all

common nationally.

11

Other groups

In the pitfall traps other invertebrate groups were represented. One or two species were identified

but the majority of ‘others’ are still awaiting identification should expertise become available.

These unidentified specimens (approximately a dozen tubes containing predominantly flies -

Diptera) are stored in 70% alcohol, which should preserve them indefinitely. If there are

possibilities of identification then they can be transferred to appropriate specialists.

The slugs were half rotted, almost un-identifiable and it was impossible to quantify numbers. The 3

species recorded were all common, yet there were not any woodland Limacid slugs - eg Limax

cinereoniger or Malacolimax tenellus, in the samples, which would have been expected from this

type of deciduous woodland habitat in the Chilterns.

A small number of aculeate hymenoptera – bumble bees and solitary bees were recorded from a

pan trap put out on my first visit to the Common. Again, all were common species.

Recommendations

• For the jumping spider Marpissa muscosa – allow fallen branches and dead trees to remain

in situ to decompose and break down naturally.

• For the ground beetle Agonum sexpunctatum – maintain wetland habitat at pitfall trap site

B in Compartment F and the immediate surrounding area.

• During the limited survey time available it was apparent that the South Meadow was

probably the richest in terms of invertebrate diversity. Should any further funding become available

this area would benefit from additional survey work – in the form of pitfall trapping, suction

sampling and general collecting. As mentioned above there is potential for recording a much

greater number of spiders at Moorend and South Meadow would be a priority area for this.

12

• Throughout the whole site the maintenance and encouragement of a wide diversity of

vegetation structure is recommended. Many invertebrate groups benefit from a varied mosaic of

vegetation structure throughout the whole year during all stages of their life cycles. The greater the

diversity of plant species within a habitat or site the higher the structural diversity will be. Kirby

(1992) states ‘The importance to invertebrates of varied vegetational structure cannot be

overstated’ and ‘Vegetation structure is important to invertebrates in every aspect and at every

scale.’ Moorend contains a diversity of tree and plant species in varied habitat types ranging from

close canopy deciduous woodland to open meadow with additional variety resulting from the

varying moisture content of the soils. As a whole the site has a high diversity of vegetation structure

and this should be encouraged (see below). Gorse Ulex europaeus, for example, is one of the most

highly structured plants and its presence on Middle Meadow provides a habitat for a range of web

spinning spiders such as Agelena labyrinthica and Cyclosa conica which would probably not be

found at Moorend if the small areas of Gorse were not there.

Other site features can be described as structure and should be included here. For example, areas

of bare ground, however small, can be critical for some invertebrates, e.g. solitary bees, and if

present on site should be conserved in the management programme. Similarly, dead wood either

lying on the ground or still on the tree is an additional structure feature which should be conserved.

Simple survey techniques and management options can be introduced to monitor and further

record invertebrates if desirable:

Where grassland mowing is part of the management programme small areas of grassland

should not be mown and should be left to die off naturally thereby maintaining some of the

vegetation structure required by those invertebrates requiring specific overwintering sites in

dead meadow and grassland vegetation.

13

To encourage solitary bee and wasp activity it would be well worth establishing a few

patches of bare ground by simply lifting small patches of turf to expose the underlying soil,

particularly in areas open to the sun where there may be the possibility of the bare ground

drying out.

The installation of solitary bee nest boxes is also a useful method of monitoring and

recording activity of these invertebrates. Specifically designed nest boxes can be purchased

or they can be simply constructed – for further information see

http://www.foxleas.com/bee_house.htm

Ground moving invertebrates will shelter under shaded areas on the ground surface.

Artificial shelter areas can be established by laying down small sections of corrugated metal

sheeting or old pieces of carpet on the ground in selected locations around the site. These

would provide an undisturbed retreat for a range of invertebrates particularly beetles and

spiders. The metal sheeting also is a favourite shelter site for slow worms and grass snakes –

particularly if located in areas exposed to direct sunlight.
