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: the species is viable and maintaining itself on a long-term basis, its natural range is not reduced, and it has a sufficient large habitat.
Poor: the species is not as critical as being unfavourable-bad, but still requires significant conservation and restoration measure to make it viable in the long-term, or to enlarged its current range, or to improve the quality and availability of its habitat.
Bad: the species is either not maintaining itself on a long-term basis and is not viable, or its natural range as been or is being drastically reduced, or its habitat is largely insufficient; the species requires major conservation and restoration measures.
Unknown: the information available for the species is scarce and does not allow a proper assessment of its conservation status.
