The low-lying landscape consists of shallow channels and extensive mudflats among islands composed mostly of muskeg.

Compared to other Key Habitat Sites in Northern Canada, particularly high densities of Arctic tern, greater white-fronted goose, loon, northern pintail, and sandhill crane frequent the area.

[10] A colony of approximately 3000 lesser snow geese have been identified at KIBS, as well as nationally significant numbers of Hudsonian godwit and whimbrel.

The short-eared owl, a Species at Risk Act-listed bird, has been records at KIBS, as well as grizzly bear, polar bear and wolverine, which are listed species by Canada's Committee on the Status of Endangered Wildlife,[11] and the highly endangered Eskimo curlew.

[12] The Lapland longspur appears to be avoiding the KIBS because of seismic lines and drilling pads brought on by natural gas exploration.
