Justification of Red List categoryThis species has a moderately small population which appears to be declining over a short time period. The reasons for this decline are largely unknown. Trend calculations are complicated by interannual variation in survey coverage and reporting across its range. Small populations of other Arctic breeding geese have shown dramatic population fluctuations and this may prove to be the case for this species. The species is precautionarily listed as Vulnerable, however if it is found that recent increases are genuine and not a result of improved monitoring efforts or range shifts the species may warrant further downlisting.
