Species Action Plans Roseate Tern (Sterna dougalii)
This species has an extremely large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence 30% decline over ten years or three generations). The population size is very large, and hence does not approach the thresholds for Vulnerable under the population size criterion (10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern. [source: Birdlife.org]
[Roseate Tern (Sterna dougalii) Europe 1999]
The Roseate Tern is a BirdLife International ‘Species of European Conservation Concern’ Category 3 (SPEC 3) indicating that, although its global population is not concentrated in Europe, it does have an unfavourable conservation status there (Tucker & Heath 1994). The Roseate Tern is listed on Appendix II of the Bonn and Bern Conventions, and on Annex 1 of the European Community Directive on the Conservation of Wild Birds and so is a species for which member states must take special conservation actions and notify suitable sites as Special Protection Areas (SPAs). The whole European range of this species lies within the boundary of the EU; in France, Republic of Ireland, Portugal (Azores, Selvagens/Madeira), the UK and Spain (Canary Islands). The decline in Roseate Tern numbers in western Europe (and in some populations elsewhere) has been severe, long-lasting and well documented, although the reasons behind this decline remain obscure. It is possible that the cause of the decline lies outside Europe – factors acting either in the Azores or in the wintering quarters in coastal areas of West Africa could be responsible. Little is known of the threats experienced by this species in the Azores and research is currently being undertaken to study it there. From 1985 to 1994, the RSPB and ICBP/BirdLife International funded an educational programme by the Government of Ghana to try to reduce the incidence of winter trapping in Ghana and Senegal. This was implemented by the ‘Save the Seashore Birds Project, Ghana’. In 1994, the project’s activities were taken over by the Ghana Wildlife Society. There was a similar project in Senegal, run by the Ligue pour la Protection des Oiseaux (LPO).
