Conservation status

EU conservation status

Conservation status assesses every six years and for each biogeographical region the condition of habitats and species compared to the favourable status as described in the Habitats Directive. The map shows the 2013-2018 assessments as reported by EU Member State. Assessments are further detailed in the summary document available behind the link below.

Good: A habitat is in a situation where it is prospering and with good prospects to do so in the future as well
Poor: A habitat is in a situation where a change in management or policy is required to return the habitat to favourable status but there is no danger of disappearance in the foreseeable future
Bad: A habitat is in serious danger of disappearing (at least regionally)
Unknown: The information available for the habitat type is scarce and does not allow a proper assessment of its conservation status
