CHANTREY INLET LOWLAND

This ecoregion is associated with lowlands surrounding Chantrey Inlet and Adelaide Peninsula. The mean annual temperature is approximately -12°C with a summer mean of 4.5°C and a winter mean of -28°C. The mean annual precipitation ranges 125-200 mm. This ecoregion is classified as having a low arctic ecoclimate. It is characterized by large areas of exposed, sparsely vegetated bedrock, in association with 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 sites; wet sites are dominated by sphagnum moss and sedge tussocks. Near the coast, the surface is mantled by silts and clay of postglacial marine overlap, and is underlain by massive Archean rocks that form a level to undulating plain that reaches about 300 m asl in elevation in its southern section. Turbic and Static Cryosols developed on discontinuous, thin, sandy moraine, level alluvial, and marine deposits are the dominant soils in the ecoregion. The east and west sides of Chantrey Inlet are underlain by continuous permafrost with low ice content. The northern half of the Adelaide Peninsula is characterized by continuous permafrost with medium to high ice content in the form of ice wedges and massive ice bodies. Characteristic wildlife includes caribou, polar bear, wolf, fox, hare, raptors, shorebirds, waterfowl, walrus, seal, and whale. Land uses include trapping, hunting, and fishing.

This ecoregion is part of the Southern Arctic ecozone.
