Towardsbiophysicalmappingofecosystems–08.02.2013 1
Towardsbiophysicalmappingofmajorecosystems Draft proposal supporting the analytical framework for Mapping and Assessment of Ecosystems and their Services (MAES) Contributing authors (EEA): Branislav Olah, Andrus Meiner, Markus Erhard, Eva Royo Gelabert, Johnny Reker Key objective
Developing a European approach for spatial representation of main biophysical complexes providing quantitative aspect of ‘state of ecosystems’.
Specific objectives Providing response to policy requirement ‘mapping ecosystems’ (i.e. EU
Biodiversity Strategy to 2020). Taking stock of existing EEA reporting on ecosystems (e.g. Baseline 2010),
available European data sets (e.g. Corine Land Cover) and European habitat lists (e.g Habitats Directive Annex I, EUNIS).
Creating links to ecosystem assessment, mapping of ecosystem services and ecosystem capital accounting approaches, as they evolve in other work areas.
Outcome Overall EEA proposal for implementing ‘ecosystem mapping’ at European level. Note: This paper presents a pragmatic approach to the spatial delineation of Europe’s ecosystems by applying accepted ecosystem classification systems (EUNIS) and existing spatial datasets with European coverage (CLC). It is a living document providing an overview of existing assessment methods and datasets and reflecting upon recent developments and discussions within the MAES working group. It is being used in on-going EEA’s activities on ecosystem mapping and assessment (ETC-SIA) and in the Assessment of ecosystems and their services - An analytical framework for ecosystem assessments under Action 5 of the EU Biodiversity Strategy to 2020 discussion paper.

1. What is ‘ecosystem’ and what is ‘mapping’?
1.1 Definition of ecosystem
Ecological science defines ecosystem as a complex of living organisms with their environment and their mutual relations. Although, this definition applies to all hierarchical levels (from a single microorganism’s ecosystem to Earth’s biomes), for practical reasons local (habitat, biotope) or landscape level ecosystems are mapped and assessed (Box 1). BOX 1. Theoretical (generic) model of ecosystem presenting ecosystem components’ (subsystems) relations Relationships of biotic and other ecosystem components. Subsystem Providing to biota Receiving from biota Climate Heat (energy) and water Impact to micro and local climate Soil Substrate, nutrients, water supply Soil erosion protection, source of
soil carbon Hydrology Water based processes Surface run-off regulation Relief Aspect, water and gravitation
processes Regulation of water-gravitation processes (floods…)
Bedrock Underpinning relief and soil, aquifers
Biotic weathering processes
Definition of an ecosystem adopted by the Convention on Biological Diversity (CBD)1: “ecosystem is a dynamic complex of plant, animal and micro-organism

communities and their non-living environment interacting as a functional unit” (United Nations 1992:Article 2). Definition by Millennium Ecosystem Assessment (MEA)2: A practical approach to the ‘spatial delimitation of an ecosystem’ is to build up a series of overlays of significant factors, mapping the location of discontinuities, such as in the distribution of organisms, the biophysical environment (soil types, drainage basins, depth in a water body), and spatial interactions (home ranges, migration patterns, fluxes of matter). A useful ecosystem boundary is the place where a number of these relative discontinuities coincide. Ecosystems within each category share a suite of biological, climatic, and social factors that tend to differ across categories. More specifically, there generally is greater similarity within than between each category in:
climatic conditions; geophysical conditions; dominant use by humans; surface cover (based on type of vegetative cover in terrestrial ecosystems or on
fresh water, brackish water, or salt water in aquatic ecosystems); species composition; resource management systems and institutions.
The EU Habitats Directive3does not define ecosystems but natural habitats: natural habitats mean terrestrial or aquatic areas distinguished by geographic, abiotic and biotic features, whether entirely natural or semi-natural. 1.2 Mapping of ecosystems Ecosystem mapping is spatial delineation of ecosystems following agreed ecosystem classification (ecosystem types). Ecosystem classification strongly depends on mapping purpose and scale. Mapping in broader sense may also include mapping of status or health as the result of monitoring of ecosystems’ quality. Global approaches to ecosystem classification and mapping (or reporting) apply two basic principles: typological and regional (or their combination) (ANNEX 1). Typological approach divides nature into ecosystem types – classes that can occur at more geographical locations (i.e., temperate broadleaf and mixed forests). Regional approach describes ecosystems from a regional (spatially unique) perspective (i.e., Dinaric mixed forests). In the context of policy e.g. EU Biodiversity 2020 Strategy, ecosystem mapping also aims to satisfy management perspective and is largely determined by data availability. In the absence of agreed and regularly updated European ecosystem map, the task of mapping could be interpreted as aggregation of some proxy spatial information that describes as good as possible the biophysical complex on the ground surface and adequate representation in the seas. Such mapping should aim at providing quantitative aspects of ‘state of ecosystems’.

For practical purpose and strong links to the emerging GMES Land monitoring services, the proposed method of ecosystem mapping is based on the EU Biodiversity 2010 Baseline approach. This implies that CORINE land cover classes as used in GMES are aggregated in most meaningful way to represent broad-scale ecosystem areas. This aggregation is based on detailed expert analysis of relations between land cover classes and habitat classification systems (i.e. EUNIS) to ensure consistency between these approaches. The resulting cross-walk schema is used as look-up table for spatial re-aggregation of land cover units in to broad-scale ecosystems suitable for European ecosystems assessment (ANNEX 3). Ecosystem mapping approach also has to be practical for setting up ecosystem accounting. For that reason, constructed broad-scale ecosystem zones are converted in to reference grid of 1 km2 cells (based on respective INSPIRE specifications). Records of ecosystems presence and where possible, key qualitative properties, in each cell across Europe provides direct input layer for accounting systems and enables assessment of ecosystems and their services (Fig 1). Figure 1. Concept for ecosystem mapping at European scale
In its Target 2, Action 5 the EU biodiversity strategy to 2020 clearly identifies a need to map ecosystems and to assess their state.
Towardsbiophysicalmappingofecosystems–08.02.2013 5
EU biodiversity strategy to 2020 Target 2 - By 2020, ecosystems and their services are maintained and enhanced by establishing green infrastructure and restoring at least 15 % of degraded ecosystems) Action 5 - Improve knowledge of ecosystems and their services in the EU. Member States, with the assistance of the Commission, will map and assess the state of ecosystems and their services in their national territory by 2014, assess the economic value of such services, and promote the integration of these values into accounting and reporting systems at EU and national level by 2020. In order to integrate national assessments at pan-European scale, the ecosystem mapping shall apply an ecosystem classification that is thematically applicable for the whole EU territory and with a respective spatial resolution. It shall be typological - without regional and zonal classes. Production of regional or zonal aggregation of ecosystem types as well as scaling upwards to useful reporting units will be, however, possible applying spatial tools (GIS or OLAP cube). 2. Existing EEA approach for spatial representation of terrestrial, freshwater
and marine ecosystems for environmental assessments Since the inception of the European Environment Agency there has been a continuous work programme to develop a comprehensive framework for classification of European habitats and to provide descriptions of European habitat types. The habitat classification forms an integral part of the European Nature Information System (EUNIS), developed and managed by the European Topic Centre for Nature Protection and Biodiversity (ETC/NPB). In order to assess ecosystems’ stock and its changes in Europe (EU Biodiversity baseline4 and SEBI 004 Ecosystem coverage indicator5) a spatial representation of European ecosystems was produced by a combination of EUNIS (level 1) classification6 and spatial data from Corine Land Cover (Table 1). CLC classes were aggregated into either 8 (EU Biodiversity baseline7) or 13 ecosystem types (SEBI 004 Ecosystem coverage indicator8). Table 1.

The Baseline 2010 does not recognise unvegetated areas and artificial areas (artificial ecosystem as such is not amongst reported ecosystem types in Baseline) as this approach focused on existing EU policy or policy sectors. Habitat complexes are missing in both Baseline and SEBI approach as they are not directly represented in the CLC classification. Additional ecosystem types (compared to Baseline) in SEBI are merely using less aggregated CLC classes which can be easily re-aggregated to EUNIS like types. Coastal habitats in EUNIS include only genuine coastal habitats affected by spraying salt water whilst in Baseline and SEBI more traditional coastal CLC classes are included (beaches, coastal wetlands and coastal waters without class sea and ocean). 3. Update of ecosystem classification Based on analysis of existing approaches EEA has worked on an update of ecosystem classification. The proposal for level 1 and 2 (Table 2, for detailed description see ANNEX 2) corresponds directly with EUNIS habitat classification and SEBI 004 indicator on ecosystem coverage. It is relevant for EU policies and it is compatible with global ecosystem classifications. It is typological (enabling comparison between different parts of the Europe’s territory), keeps pan-European scale and takes into consideration regular mapping aspect (applying CLC data for spatial delineation).

Following paragraphs provide a brief description of proposed ecosystems types: Urban Urban ecosystems are areas where most of the human population lives and it is also a class significantly affecting other ecosystem types. Urban areas represent mainly human habitats but they usually include significant areas for synanthropic species. This class includes urban, industrial, commercial and transport areas, urban green areas, mines, dump and construction sites. Cropland Main food production area both intensively managed ecosystems and multifunctional area supporting many semi- and natural species along with food production (lower intensity management). It includes regularly or recently cultivated agricultural, horticultural and domestic habitats and agro-ecosystems with significant coverage of natural vegetation (agricultural mosaics). Grassland Area dominated by grassy vegetation (including tall forbs, mosses and lichens) of two kinds – managed pastures and natural (extensively managed) grasslands Woodland and forest Area dominated by woody vegetation. Climax ecosystem type on most of the area supporting many ecosystem services, Transitional woodland is included. Heathland and shrub Area with vegetation dominated by shrubs or dwarf shrubs. Mostly secondary ecosystems with unfavourable natural conditions. It includes moors, heathland and sclerophyllous vegetation. Sparsely vegetated land Inland unvegetated or sparsely vegetated habitats (naturally unvegetated areas). Ecosystems with extreme natural conditions that might support valuable species. It includes bare rocks, glaciers, dunes, beaches and sand plain.
Towardsbiophysicalmappingofecosystems–08.02.2013 8
Wetlands Marshes and peatbogs with specific plant and animal communities supporting water regulation and peat-related processes. This class includes mires, bogs and fens. Rivers and lakes Permanent freshwater inland surface waters. This class includes water courses and bodies. Marine inlets and transitional waters Marine inlets and transitional waters are ecosystems on the land-water interface under the influence of tides and with salinity higher than 0.5 ‰. They include coastal wetlands, lagoons, estuaries and other transitional waters, fjords and sea lochs as well as embayments.
Coast
The coastal areas refer to coastal, shallow, marine systems that experience significant land-based influences. These systems undergo diurnal fluctuations in temperature, salinity and turbidity, and are subject to wave disturbance. Depth is between 50 and 70 m.
Shelf
The shelf refers to marine systems away from coastal influence, down to the shelf break. They experience more stable temperature and salinity regimes than coastal systems, and their seabed is below wave disturbance. They are usually about 200 m deep.
Open ocean The open ocean refers to marine systems beyond the shelf break with very stable temperature and salinity regimes, in particular in the deep seabed. Depth is beyond 200 m. 4. Review of relevant European spatial data sets Table 3 presents key European datasets available at EEA that may be applied for ecosystems spatial delineation (addressing stock) and for ecosystems quality.

Main implementation steps of the proposed ecosystem mapping approach Data model Ecosystem mapping of terrestrial ecosystems, lakes and transitional water parts of marine will follow existing CLC data model – all datasets assimilated to raster (100m) and reported in 1km grid. Sharing CLC spatial data model makes it fully compatible with the biophysical part of the ecosystem accounting and enables its combination with ecosystem services. Delineation of marine ecosystems will be based on existing marine datasets (i.e. EUSeaMap) and additional modelling of ecosystem presence based on ancillary data. Ecosystems of linear nature as watercourses will be mapped by using existing delineation from WFD reporting and they will be kept separate as linear data. Their integration with area data will be provided by ECRINS data model that defines relation of each linear element to its areal surroundings. Ecosystem stock mapping Generic approach for European ecosystems’ stock mapping will apply CLC classes for spatial delineation of level 1 and 2 ecosystem types (ANNEX 3). In order to assess how ecosystems support ecosystem services (in the ecosystem – ecosystem service matrix approach) more detailed hierarchical level 3 of ecosystem types may be needed. Following the classification criteria of EUNIS will require application of various ancillary datasets beyond CLC (such as biogeographical regions, elevation or proximity to sea) (ANNEX 4). Ecosystem quality mapping Ecosystem quality (health) is crucial for ecosystem functions and services. Quality may be addressed either by direct monitoring or by using ancillary data or assessments as proxies. As identified in Table 3 there are currently only two European datasets providing information about quality of ecosystems the Habitats Directive Art. 17 for habitats conservation status and the WFD ecological status reporting for water courses and bodies.
Towardsbiophysicalmappingofecosystems–08.02.2013 11
Even if their original purpose and design (spatial resolution and monitored parameters) may vary from the proposed ecosystem typology, they are being used as indicators for ecosystem quality in ecosystem accounting. The reporting may be re-designed or broadened in future to better respond to the EU biodiversity strategy to 2020. EEA currently explores options for using pan-European phyto-sociological survey results (releves) as ecosystem quality indicators. Change mapping Mapping of ecosystem change shall reflect both stock and quality of ecosystems. In order to assess changes, quantitative and qualitative information have to be reported separately or combined as in the currently developed ecosystem capital accounting approach. Implementation example of proposed approach as applies for 2000-2006 is presented in ANNEX 5.
Towardsbiophysicalmappingofecosystems–08.02.2013 12
ANNEX 1 Examples of ecosystem classifications
A. Typological classification applied by the Convention on Biological Diversity To make a global assessment of the losses of biomes, ecosystems and habitats, it is important to obtain complete coverage of all major types of biomes/ecosystems, even if data quality varies. Data sources include global remote-sensing data and national land-cover maps and statistics. For some biome/ecosystem types, the identified datasets will yield sufficient data points to give trend information relevant to the 2010 target assessment. For others, appropriate global datasets are yet to be identified or need to be acquired (CBD). Based on current and short-term future availability of trend information, the following major ecosystem types are considered ready for immediate indicator implementation (CBD): (a) Forests (including different forest types, notably mangroves); (b) Peatlands (as a component of inland waters or forests); (c) Coral reefs (as a component of marine and coastal ecosystems); (d) Croplands (as a component of agricultural systems); (e) Grasslands/savannahs (as a component of dry and sub-humid lands); (f) Polar/ice. In the future efforts need to be made to apply the indicator to the following ecosystem types to ensure coverage of all thematic areas recognized by the Convention: (a) Inland wetlands (other than those already covered as peatlands); (b) Tidal flats/estuaries (as an additional component of coastal ecosystems); (c) Seagrass beds (as an additional component of coastal ecosystems); (d) Dry and sub-humid lands (other than grasslands/savannahs); (e) Urban areas.

C. Reporting Categories used in the Millennium Ecosystem Assessment For reporting the global Millennium Ecosystem Assessment (MEA) findings, a practical, tractable, sufficiently rich classification based on 10 classes or systems has been developed. Thus, for example, the MEA will report on “forest systems,” defined to be areas with at least 40 percent canopy (tree) cover. Using this approach, a forest system will contain a variety of different types of ecosystems, such as freshwater ecosystems, agroecosystems, and so forth. But all areas within the boundaries of the forest system as defined here will tend to share a suite of biological, climatic, and social factors, so the system categories provide a useful framework for analysing the
Towardsbiophysicalmappingofecosystems–08.02.2013 14
consequences of ecosystem change for human well-being. Because the boundaries of these reporting categories overlap, any place on Earth may fall into more than one category. Thus a wetland ecosystem in a coastal region, for instance, may be examined both in the MEA analysis of “coastal systems” as well as in the analysis of “inland water systems.” Millennium Ecosystem Assessment Reporting Categories (Limits for Mapping) Category Central Concept Marine Ocean, with fishing typically a major driver of change Coastal Interface between ocean and land, extending seawards to about the
middle of the continental shelf and inland to include all areas strongly influenced by the proximity to the ocean
Inland water
Permanent water bodies inland from the coastal zone, and areas whose ecology and use are dominated by the permanent, seasonal, or intermittent occurrence of flooded conditions
Forest Lands dominated by trees; often used for timber, fuelwood, and non-timber forest products
Dryland Lands where plant production is limited by water availability; the dominant uses are large mammal herbivory, including livestock grazing, and cultivation
Island Lands isolated by surrounding water, with a high proportion of coast to hinterland
Mountain Steep and high lands Polar High-latitude systems frozen for most of the year Cultivated Lands dominated by domesticated plant species, used for and
substantially changed by crop, agroforestry, or aquaculture production
Urban Built environments with a high human density The MEA’s classification system is typological but it introduces also regional or zonal types – coastal, island and mountains.

ANNEX 4. Spatial delineation of EUNIS level 2 ecosystem types by applying ancillary datasets (draft table for ETS SIA 2013 implementation plan) EUNIS was designed as a theoretical hierarchical classification of habitats following defined criteria without intention for their biophysical mapping. However, for practical reasons a EUNIS-CLC crosswalk9 was proposed. Appointing CLC classes to respective EUNIS classes, in some cases, result in one-to-many or many-to-many relations (CLC classes belonging to more than one habitat type). A feasible option how to spatially delineate EUNIS habitats (level 1 and 2) using CLC as base information would be to apply ancillary datasets (following EUNIS breakdown criteria10) that will appoint a concrete CLC polygon to respective ecosystem type by its location (according to ancillary datasets). Level 1 types L1 explained by Level 2 classes Datasets for mapping*

ANNEX 5. SEBI04 ecosystem coverage in 2006 and its changes 2000-2006 In order to test the proposed classification system we applied 13 SEBI04 ecosystem types on Corine Land Cover 2006 (v.16). The map and the pie chart show the ecosystem stock in 2006. Changes between 2000 and 2006 are presented in the ‘Ecosystem coverage summary balance table 2000-2006’ and the bar diagram below. An even distribution of 9 terrestrial classes justifies the applied CLC grouping (especially valid for sparsely vegetated land comprising bare rocks, sparsely vegetated, burnt and glaciers ecosystems that separately would have only minimal coverage). Marine ecosystem (level 1) is currently represented only by CORINE Land cover class 5.2.3 ‘Sea and ocean’ that is representing the zone seaward of the lowest tide limit and extends to the limit of 12 nautical miles in the sea. This class appears only in change assessment. Transitional woodlands represent significant ecosystem coverage (6%) but more importantly it is the most dynamic ecosystem type between 2000-2006 with a total turnover of 16.2% and a net increase of 7.6%. Mapping this type separately provides important information on ecological processes in forested (management) and agricultural (land abandonment) areas. CLC based assessment of ecosystems coverage and its changes if fully compatible with land accounting methodology that enables to analyse both ecosystems stock and changes. Note: The current results present classes Agricultural mosaics, Transitional woodland and Coastal ecosystems separately as they were prepared following the SEBI04 methodology. In the proposed ecosystem classification (table 2) Agricultural mosaics are merged with Cropland, Transitional woodland are part of Woodland and forest and Coastal ecosystems are mainly within Marine ecosystems (Beaches belong to Sparsely vegetated land).
