Status summary
Canada Geese have increased rapidly, at a rate estimated at 9.3% per annum in Britain between the 1988–91 Atlas period and 2000, with no sign of any fall in the rate of increase (Austin et al. 2007). Most of this increase, amounting to 166% during that period, has been in areas previously with low goose densities. The WBS sample became large enough for annual monitoring in 1980, since when further, apparently accelerating, increase on linear waterways occurred during the 1990s. WBS results for recent seasons suggest little change in this habitat since 2004. 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 (Banks et al. 2006).
