Habitats

Readers may find the following background documents useful in understanding how the assessments have been made:
 
  1. Guidance from the European Commission on making conservation status assessments, especially the data matrices in the appendix.
  2. The approach taken by JNCC to reach these conclusions. 
 

 

The reporting format set by the European Commission requires assessment of the conservation status of each habitat on Annex I of the Directive.  The habitats for which the UK has responsibility are listed in the table below.  Two of these habitats (H6210 and H6211) are very similar and a combined assessment has been prepared for them (listed under H6210).
