  1. Reporting – Article 17Habitats Committee, 16 October 2007 Assessing Conservation Status for a Biogeographical Region Carlos Romão, Doug Evans & Iurie Maxim

  2. Discussed by the Scientific Working Group (February 2007) • Expert meeting held in Paris 14 June 2007 • ‘Assessing the conservation status of habitats and species at the EU level’ (Doc.HAB 07-06-06b, June Habitats Committee) suggested 3 possible methods • Methods tested with data from Article 17 reports from 4 Member States by the ETC-BD in September 2007 • Expert meeting held in Paris 25 September 2007 • Paper for SWG produced to be discussed next month (SWG-07-11-02) – circulated to Habitats Committee

  3. 3 methods proposed • Use the evaluation matrices using primary data from Member States • Weighted aggregation of the four conservation status parameters – range, area/population, structure & functions/habitat spp, future prospects - using the rules for combining the four sub assessments given in the annexes (final line of the matrices) • Weighted aggregation of overall conservation status assessment

  4. All 3 methods rely, at least partially, on weighting the contribution of each MS • Weighting can be by area of distribution (habitats, species ), population (species) or range (habitats, species )

  5. Example: 601 cells occupied 249 cells in Poland 42% of ‘population’ in Poland Grid cells occupied by Arnica montana in the Continental region based on distribution maps from the MS and the ETRS LAEA89 10x10 km grid

  6. Tests show all 3 methods can work & give similar assessments (so far) The Scientific Working Group will be asked to discuss several issues including • Thresholds • Trends And to give an opinion on the ETC-BD’s proposal to use Method 1 – use of primary data - wherever possible
