This is a small elongated ecoregion extending northeast from Winokapau Lake and bordering the western extensions of the Lake Melville ecoregion (105). It is marked by cool summers and very cold winters. The mean annual temperature is approximately -2.5°C. The mean summer temperature is 9.5°C and the mean winter temperature is -15.5°C. The mean annual precipitation ranges 700-900 mm. The ecoregion is classified as having a low subarctic ecoclimate. Its forests are transitional, both to tundra and alpine tundra vegetative communities to the north, and to the closed cover of typical coniferous boreal forests to the south. Open stands of lichen-black/white spruce woodlands are dominant. Black spruce is the climatic climax species, and trembling aspen reaches its northern limit in this ecoregion. Balsam fir is restricted to rare medium-textured sites. The ecoregion is primarily a rolling plain of exposed bedrock with numerous lakes. Some isolated rugged hills stand above the general surface with elevations ranging 310-650 m asl. Composed of exposed massive Archean granites, granitic gneiss, and acidic intrusives, a sparse cover of hummocky, discontinuous morainal veneers dominates the upper surfaces of the ecoregion. Bare bedrock outcroppings are common, and Humo-Ferric Podzols are the dominant soils with significant inclusions of Ferro-Humic Podzols, Mesisols, and Organic Cryosols. Permafrost is found in isolated patches with low ice content, mainly in wetlands. This ecoregion provides habitat for caribou, small mammals, waterfowl, and other birds. Land use activities include hunting and trapping, fishing, and outdoor recreation.
This ecoregion is part of the Taiga Shield ecozone.
