The Ross’s Goose was considered a rare species in the early part of the last century, but its numbers have increased greatly over the last 50 or so years (Alisauskas et al. 2012). The species was designated as overabundant in Canada in 2014, and is subject to special conservation measures to control its numbers in western Canada. The total number of Ross’s Goose is difficult to estimate using traditional survey techniques due to the sheer size and remoteness of the species' nesting range, the high densities of nesting birds, and its complete overlap with Snow Geese during the nesting season (Alisauskas et al. 2012). Recently, Alisauskas et al. (Alisauskas et al. 2009, Alisauskas et al. 2012) suggested that Lincoln’s approach (Lincoln 1930) could be used to estimate the population size of Ross’s Goose. Population growth over the longer term seems to have slowed and stabilized at about 1.7 million adult birds since 2012. The Ross' Goose is above the highest acceptable level relative to its national population goal. Detailed information on the population status of waterfowl species is available in the Population Status of Migratory Game Birds in Canada report (summarized version).
