Saving wetlands for wildlife & people

Background

Most authorities currently recognize five races of Bean Goose (e.g. Wetlands International 2006). These fall into two groups: those breeding in tundra regions and those breeding in forested taiga areas to the south. There is overlap between these races, however, and the taxonomy of Bean Geese is still uncertain. Two races Anser fabalis rossicus (Tundra Bean) and A. f. fabalis (Taiga Bean) are found in the Western Palearctic and both occur in Britain, although the majority of birds seen here are of the latter race. Due to their widespread distribution, overlapping winter range and the difficulties of separating different races in the field, deriving population estimates of these two sub-species is problematic.



   
Goose & Swan Monitoring
WWT home | JNCC home | SNH home
The Goose & Swan Monitoring Programme (GSMP) monitors numbers and breeding success of the UK's geese and swans during the non-breeding season. GSMP is organised by the Wildfowl & Wetlands Trust (WWT) in partnership with the Joint Nature Conservation Committee (on behalf of CCW, NE and CNCC) and Scottish Natural Heritage.
