The Mid-Canada Boreal Plains Forests is a taiga ecoregion of Western Canada, designated by One Earth.

The area has a subhumid mid-boreal ecoclimate with short summers (average temperature 14°C) and long, cold winters (ave. -15°C) and patches of permafrost in the lowlands.

[2] These forests, like so much of Canada at this latitude, are a mixture of conifers and deciduous trees including quaking aspen (Populus tremuloides), balsam poplar (Populus balsamifera), white spruce (Picea glauca), paper birch (Betula papyrifera), black spruce (Picea mariana), jack pine (Pinus banksiana) and balsam fir (Abies balsamea).

The plain to the south of the lake is home to moose, coyote (Canis latrans), and eastern cottontail (Sylvilagus floridanus) as well.

Birds include ducks, geese, American white pelican (Pelecanus erythrorhynchos), sandhill crane (Grus canadensis), ruffed grouse (Bonasa umbellus) and common loon (Gavia immer) The wetlands of the region, such as Cumberland Lake, are an important refuge for migratory birds and include the most important breeding populations of the endangered whooping crane in North America.
