Sammanfattning

For Article 17 reporting in 2025, it is required to assess the habitat condition of forest habitat types by classifying the proportions of their areas as ‘good’, ‘notgood’, or ‘unknown’. Additionally, short-term trends of areas classified as being in ‘good’ condition should also be evaluated.

In Sweden, habitat condition has been assessed for a subset of areas within Natura 2000 as part of a ‘basic inventory’ conducted by County Administrative Boards, mainly during early 2000’s. Currently, systematic monitoring of forest habitat types is conducted by the Swedish National Forest Inventory (NFI) and National Inventories of Landscapes in Sweden (NILS). In these inventories, several variables reflecting habitat quality are recorded. However, an overall assessment of habitat conditions for Article 17 reporting has not yet been conducted.

This PM proposes and documents a methodology for assessing habitat condition and short-term trends for areas classified as being in ‘good’ condition for forest habitat types in Sweden. Following national guidelines for assessing the condition of Natura 2000 forest habitat types, we selected relevant variables from samplebased inventories (e.g., NFI, NILS) for habitat quality assessment. The criteria, developed in consultation with SEPA and SFA, are described alongside the resulting findings. Finally, we outline a framework for applying these results in Article 17 reporting, in line with SEPAs and SFAs requests.
