European Topic Centre on Biological Diversity Preparation of the Atlantic Natura 2000 Seminar Draft pre-scoping document 1 st Steering Group Meeting, , Brussels Marita Arvela and Mora Aronsson, European Topic Center on Biological Diversity

European Topic Centre on Biological Diversity In this presentation: Draft pre-scoping document Data and methods used Results – aiming to aid the selection of habitat clusters Other supporting elements Questions to the Steering Committee

European Topic Centre on Biological Diversity DATA & METHOD USED Art 17 data of Excluded: species listed in Annex V only  Atlantic region: 120 habitat types and 226 species covered obirds data not in the analysis Clustering of habitat types and species –so called “Baseline grouping” used as a basis to produce adjusted habitat grouping for Atlantic region (as for the Pilot Seminar) –some habitat types & species may appear in 2 different groups

European Topic Centre on Biological Diversity Proposed habitat groups Coastal Freshwater Forests Grasslands Heaths Marine Rocks Scrubs Wetlands

European Topic Centre on Biological Diversity How the results were calculated? 1. Criteria for prioritization Number of MS where species/habitat types are present (criterion A) Species and habitat types at unfavourable conservation status (criterion B) Negative trend using certain parameters (criterion C) 2. Filtering species and habitat types: - priority index calculated using A(B + C) for each species and habitat type

Test to use weighting (tested for the Pilot Boreal Seminar) Tested for conclusions of unfavourable conservation status (criterion B) & trend information (criterion C) No major changes in results, but potential constraints detected

European Topic Centre on Biological Diversity OTHER SUPPORTING ELEMENTS Already available (see table under section 5): Positive trend Coverage of Natura 2000 network for the habitat types and species Will be made available: Information on pressures/habitat group Conclusion of CS and parameters “area” & “structure and functions” (habitat types) and “population” & “habitat for the species” (species) Information sheets for selected habitat types

European Topic Centre on Biological Diversity Pressures (example, Boreal region)

European Topic Centre on Biological Diversity Example of the use of CS conclusion & certain parameters (Boreal region)

European Topic Centre on Biological Diversity Questions to the Atlantic Steering Committee? Do you agree on the method proposed? If yes, which algorithm to use, A*B or A(B+C)? Do you agree: Annex IV species are covered in the analysis, but species listed only in Annex V are excluded in the analysis? Do you want to delete species and habitat types which occur only in one Member State from the analysis? To agree how to include Birds: Annex I bird species or more?

European Topic Centre on Biological Diversity Thank you for your attention
