Every 6 years EU Member States are required to report on the sizes of and trends in populations of birds (Article 12 of the Birds Directive) and on the conservation status of and trends in targeted habitats and species (Article 17 of the Habitats Directive) within their European territories.

The EEA, together with its European Topic Centre on Biological Diversity and consultants from the European Commission, compile and process the reports from the Member States. In addition, they assess the conservation status of species and habitats at the EU level.

These data are from the reporting period 2013-2018.
