Un bilan des modalités d’évaluation de l’état de conservation des habitats forestiers dans 399 sites Natura 2000

Abstract : 399 Natura 2000 objectives documents covering at least one forest natural habitat were analysed so as to characterise the link between evaluation of the conservation status of habitats according to the standard data forms and the evaluation derived from Objectives Documents. The first thing that comes out of these analyses is that there are a great variety of descriptors used for assessing conservation status. Of the 399 objectives documents analysed in 2011, 29% of the approved objectives documents made use of an evaluation method. The date of drafting of the objectives documents was found to have a significant effect on the methodology used to assess conservation status. For the objectives documents that refer to a protocol, the knowledge and clearer legal requirements acquired over time brought about a drop in the extent to which expert assessment was called on, replacing this with more robust methodologies. On the scale of individual sites, both evaluations produce statistically consistent results for only one of the nine forest habitats tested. All in all, the 399 objectives documents for Natura 2000 sites analysed deal with the question of evaluating the conservation status of forest habits superficially, which forebodes difficulties in meeting the performance obligations set out in the implementation of the Habitats directive.
