STATION NAME AND OWNER
The Bylot Island Research Station is owned and run by the Centre d’études Nordiques (CEN: Centre for Northern Studies) and in collaboration with Parks Canada (http://www.pc.gc.ca/index.aspx). The CEN secretariat is based at Université Laval, Québec, Canada.
Bylot Island is located off the northern tip of Baffin Island, Nunavut, Canada. It is accessible through the communities of Pond Inlet (Mittimatalik) and Nanisivik, both found on Northern Baffin Island. The field research covers the south plain of the island (1600 km2), but the research station is located in a large glacial valley at the southwest end of the island (73°08’ N, 80°00’ W).
BIODIVERSITY AND NATURAL ENVIRONMENT
Much of Bylot Island is covered by high mountain peaks and glaciers. The remainder of Bylot Island, and in particular its southern plain, is characterised by extensive low-elevation areas covered by heterogeneous tundra vegetation. The vegetation found in the wetlands is characterised by the presence of sedges, grasses, and many brown moss species. In contrast to the wetlands, dryer areas are found on slopes, hills and elevated terraces surrounding the valley lowlands, as well as on the rims surrounding tundra polygons. The better drained, dryer soils of these habitats allows for distinct plant communities, including forbs, grasses, and shrubs. These uplands, account for 90% of the south plain surface whereas wetlands account for only 10%. The wetlands of the south plain are a habitat of rare plant quality and productivity for an arctic environment. Benefiting from this “polar oasis” are more than 360 species of plants, 10 mammal species, and 74 bird species. Considered as an important site for many migratory birds, Bylot Island was declared a Migratory Bird Sanctuary in 1965. The south plain holds one of the world’s largest breeding colonies of greater snow geese and the wetlands of the Qarlikturvik valley represent their main brood-rearing site on the island. In addition to the geese, other herbivores are the brown and collared lemmings, Arctic hare, and rock ptarmigan. The main terrestrial predators are the Arctic fox, long-tailed jaeger, parasitic jaeger, glaucous gull, common raven, and snowy owl. Food web relationships are summarised in Gauthier et al. (2011): Ecoscience 18: 223-235. Established in 2001, Sirmilik National Park encompasses most of Bylot Island, except for a few pockets that are Inuit-owned lands. Covering an area of 22 000 km2, this park extends to the northern part of Baffin Island. Sirmilik (which means “place of glaciers” in Inuktitut) reflects the complex of glaciers and ice caps covering most of Bylot Island.

The current ecological studies on Bylot Island started in 1988 as a joint collaboration between Université Laval (CEN) and the Canadian Wildlife Service (Quebec region). The initial goals of the study were to initiate a demographic study of the greater snow geese population through a long-term marking program, and to assess the impact of goose grazing on the A type of ecosystem in which tree growth is limited by low temperatures.

GENERAL RESEARCH AND DATABASES
A central theme of the research conducted here is trophic interactions in the arctic tundra in relation to environmental changes and greater snow goose ecology, but also long-term monitoring of animal populations, vegetation and climate of the Arctic tundra, impacts of bird populations and Climate Change on lake ecosystems, and geomorphology of ice wedge polygons. Over the years, the Bylot Island research project has grown into one of the largest and longest ecological studies in Nunavut. Extensive data records are available at: www.cen.ulaval.ca/nordicanad or upon request (email@example.com).
No communities are present on Bylot Island. The nearest community is Pond Inlet (Mittimatalik) found on northern Baffin Island, Nunavut, Canada.
The research station is accessible by chartered flights from Pond Inlet (Mittimatalik). Research must be planned well in advance and coordinated with the station’s primary and secondary contacts Gilles Gauthier and Dominique Berteaux (dominique_berteaux@ uqar.qc.ca).
