Monitoring
Each year we conduct an aerial line transect survey of Greater White-fronted and Canada Geese during their molting period. Concerns in the 1990s about declines in the interior and northwest Alaska-breeding populations of white-fronts (aka “mid-continent population”) sparked increased attention to this species. Similar and complementary surveys are conducted on other refuges in interior Alaska to provide a regional view of distribution and numbers of white-fronts.
