Site description Akimiski Island is situated just east of the mouth of the Attawapiskat River, in mid-western James Bay. The IBA focuses on the northern shores, which are flat and marshy with beach ridges, and the interior of the island, which features numerous small lakes and ponds, as well as sedge marshlands, and fens. Also part of this site is the eastern half of the south coast, including the eel grass beds at Cape Duncan in the southeastern corner. The vegetation communities present on the island have similarities to both northern Hudson Bay associations and to southern associations.

In addition to its importance for birds, the southern region of Akimiski Island is a maternity denning area and the coasts are a summer retreat for polar bears. The mean annual temperature is approximately 2.5°C and the average rainfall and snowfall are 450 and 250 mm respectively.
