This ecoregion includes the coastal uplands of Baffin Island along Frobisher Bay and Hudson Strait, and stretches inland to include Amadjuak Lake. The mean annual temperature is approximately -11.5°C with a summer mean of 1°C and a winter mean of -22.5°C. The mean annual precipitation ranges 200-400 mm. This ecoregion is classified as having a low arctic ecoclimate. The landscape is covered by nearly continuous shrub tundra vegetation, consisting of dwarf birch, willow, northern Labrador tea, Dryas spp., and Vaccinium spp. Tall dwarf birch, willow, and alder occur on warm microsites; wet sites are dominated by willow and sedge. Irregular terrain extending westward from Frobisher Bay to Foxe Peninsula reaches elevations of about 400-500 m asl. Rock outcroppings interspersed with sandy morainal veneers and frozen organic deposits are the dominant surficial materials in the ecoregion, and Static Cryosols with Turbic and Organic Cryosols are the dominant soils. Continuous permafrost with low ice content runs from just south of Amadjuak Lake, north to Nettilling Lake, and the rest of the ecoregion is underlain by continuous permafrost with medium ice content. Characteristic wildlife includes caribou, muskox, hare, arctic wolf, fox, polar bear, raptors, walrus, seal, whale, shorebirds, and waterfowl. Land uses include trapping, hunting, and fishing. The region includes Iqaluit, the largest community in the eastern arctic, as well as the communities of Lake Harbour on Hudson Strait, and Cape Dorset on Foxe Peninsula. The population of the ecoregion is approximately 5000.
This ecoregion is part of the Northern Arctic ecozone.
