Status summary

Canada Geese have increased rapidly, at a rate estimated at 9.9% per annum in southern Britain between the 1988–91 Atlas period and 1999 (Rehfisch et al. 2002). The WBS sample became large enough for annual monitoring in 1980, since when further, apparently accelerating, increase on linear waterways has been recorded. Annual breeding-season monitoring in a wider range of habitats through BBS has shown similar strong increases in England and in the UK as a whole. Winter monitoring by WeBS shows a continuing long-term increase (Collier et al. 2005).
