Population justification: The global population has been estimated to number c.920,000-1,400,000 individuals (Wetlands International 2006), while the population in Russia is estimated at <c.100 breeding pairs and <c.50 individuals on migration (Brazil 2009).
Trend justification: The overall trend is uncertain, as some populations are decreasing, while others are stable or increasing (Wetlands International 2006). This species has undergone a large and statistically significant increase over the last 40 years in North America (1500% increase over 40 years, equating to a 101% increase per decade; data for Branta canadensis and B. hutchinsii combined, from Breeding Bird Survey and/or Christmas Bird Count: Butcher and Niven 2007).
