Status Summary
Goosanders first colonised the UK in the second half of the 19th century, spreading from Scotland into northern England in the 1940s (Holloway 1996). Between the two breeding atlases it expanded its range in northern England, and colonised Wales and south-west England. The WBS provides a reasonably representative coverage of the species to show its population expansion since 1980. The BTO organised two national surveys that demonstrated an average increase in population size of 3% per annum between 1987 and 1997 (Rehfisch et al. 1999). Reasons for this population increase are unknown.
