Preparation of the Atlantic Natura 2000 Seminar

Draft pre-scoping document

1st Steering Group Meeting, 18.1.2012, Brussels

Marita Arvela and Mora Aronsson,European Topic Center 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


DATA & METHOD USED• Art 17 data of 2001-2006• Excluded: species listed in Annex V only Atlantic region: 120 habitat types and 226 species covered

o birds 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


Proposed habitat groupsCoastal

Freshwater

Forests

Grasslands

Heaths

Marine

Rocks

Scrubs

Wetlands


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

Option 2


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


OTHER SUPPORTING ELEMENTSAlready 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

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?


Thank you for your attention
