Population status and trends at the EU and Member State levels

The Article 12 web tool provides an access to EU assessments and Member States’ data compiled as part of the Habitats Directive - Article 12 reporting process. The EU assessments have been carried out in EU 27 for the period 2008-2012 and in EU28 for the period 2013-2018.

Choose period, species and if relevant sub-specific unit.

Once a selection has been made the breeding distribution of the species can be visualized in a map.

The ‘Data sheet info’ includes notes for each assessment per species.

The ‘Audit trail’ includes the methods used for the EU assessment and justifications for decisions made by the assessors.

Please note that additional information on mouse over values and trends stands for the quality of the underlying data as reported by Member States.

The hash sign (#) under Subspecies/subspecific units-Trends or Status means that the EU population trends or EU status were not assessed at the same level as the current selection (species and subspecific unit).

In italics, additional assessment at the subspecies or population level (available only for subspecies listed in the Annexes of the Birds Directive).
