Midwestern Canadian Shield forests

The Midwestern Canadian Shield forests ecoregion, in the Taiga and Boreal forests Biome, are of northern Canada.

This is an area of rolling hills with lakes both small and large, wetlands, and rocky outcrops on the Canadian Shield in northern Saskatchewan, north-central Manitoba (north and east of Lake Winnipeg) and Northwestern Ontario. Specific areas include the Athabasca Sand Dunes, and many lakes such as Cree Lake, Upper Foster Lake and Reindeer Lake in Saskatchewan. The area has a cold climate, very cold in winter although the hills around Lac Seul are warmer and wetter than most of the ecoregion, while the Athabasca Plain and the uplands above the Churchill River and Hayes River are cooler. There are patches of permafrost throughout

Much of the landscape, including the Athabasca Plain, is the boreal forest that covers so much of Canada at this latitude, consisting of black spruce (Picea mariana), jack pine (Pinus banksiana), quaking aspen (Populus tremuloides), white birch (Betula papyrifera), balsam poplars, white spruce (Picea glauca), and balsam fir (Abies balsamea). The dominant tree of the wetlands is black spruce, while the rocky outcrops are covered with lichens.
