Abstract

This report presents the Favourable Reference Values for population size and range for the species listed in Annexes II, IV and V of the EU Habitats Directive. These reference values are used to assess the conservation status of species as required by Article 17 of the Habitats Directive. They were determined according to a protocol (checklist) and based on scientific information. Where the required scientific information was not readily available, expert judgement was used to fill the gaps. When determining the reference values, experts on each of the species groups were enlisted from the various voluntary conservation organisations, IMARES Wageningen UR (Texel and IJmuiden) and Alterra Wageningen UR. In addition, two extra questions were answered on how these reference values can be maintained or achieved, and the potential influence of climate warming.
