Ellesmere Island, at 196 236 km2, is the third-largest island in Canada, the 10th-largest island in the world and the most northerly island in the Arctic Archipelago.

Wetlands cover about 14 per cent of the land area of Canada, and are the natural habitat of over 600 species of plants, animals and insects. In addition to providing a home for these plants and animals, wetlands are an essential part of the environment because they prevent flooding, filter toxins, store groundwater and limit erosion. The most common wetland habitats are swamps, marshes, and bogs.
