Ecoregions of Canada


This ecoregion, borders on northeastern Baffin Island, has a sparse vegetative cover of mixed low-growing herbs and shrubs, consisting of moss, purple saxifrage, Dryas spp., arctic willow, kobresia, sedge, and arctic poppy. Wet sites can develop up to about 60% cover of wood rush, wire rush, and saxifrage, along with a nearly continuous cover of mosses. A humid, cold, arctic climate is marked by short, cold summers and long winters. Mean annual temperature is approximately -11.5°C. Mean summer temperature is 1°C and mean winter temperature is -22.5°C. Mean annual precipitation ranges 200-300 mm. This ecoregion is classified as having a high arctic ecoclimate. The ecoregion is up to 40 km wide, and is geologically composed of crystalline Precambrian massive rocks that occur as isolated outliers from peninsulas and fjords that extend out from the Davis Highlands. It is a gently warped, old erosion surface with discontinuous, ridged, and terraced surficial deposits. This ecoregion is underlain by deep, continuous permafrost with low ice content. Bare bedrock is common, and Turbic Cryosols on sandy colluvial, morainal, and marine deposits are the dominant soils. Characteristic wildlife includes arctic hare, arctic fox, lemming, and caribou. Polar bears are common in coastal areas. Representative birds include the king eider, rock ptarmigan, northern fulmar, plover, hoary redpoll, and snow bunting. Marine mammals include walrus, seal, and whale. The largest settlement is Clyde River, and the population of the ecoregion is approximately 600.

This ecoregion is part of the Arctic Cordillera ecozone.
