This project seeks to establish a long-term camp at Anderson Bay on Victoria Island (about 40 km east of Cambridge Bay) to study the population dynamics of lesser snow geese and Ross's geese (i.e., light geese) annually from June to July. The project is led by Mitch Weegman, Ducks Unlimited Canada Endowed Chair in Wetland and Waterfowl Conservation, and an Associate Professor, at the University of Saskatchewan. While light goose demography was studied nearly continuously since 1991 at Karrak Lake (Queen Maud Gulf [Ahiak] Migratory Bird Sanctuary) by Ray Alisauskas, the colony has declined rapidly and logistics are increasingly difficult. At the same time, the colony at Anderson Bay has increased rapidly over the last 10 years. The presence and increase in the colony has been of great interest to community members in Cambridge Bay. Further, information about the population dynamics of light geese is required by the Canadian and US governments to inform management plans for these species, as well as harvest regulations. I am proposing to move the work on breeding biology of lesser snow geese and Ross's geese from Karrak Lake to Anderson Bay. We will conduct a comprehensive project, following Karrak Lake best practices, to study arrival condition of birds, nest initiation and fate, clutch size, and other Arctic ecosystem components such as vegetation monitoring through exclosures, sea duck (king eider) population ecology, and small mammal indices.
