Flora and fauna of Manitoba

Manitoba natural communities may be grouped within five ecozones: boreal plains, prairie, taiga shield, boreal shield and Hudson plains. Three of these—taiga shield, boreal shield and Hudson plain—contain part of the Boreal forest of Canada which covers the province's eastern, southeastern, and northern reaches.

Forests make up about 263,000 square kilometres (102,000 sq mi), or 48 percent, of the province's land area. The forests consist of pines (Jack Pine, Red Pine, Eastern White Pine), spruces (White Spruce, Black Spruce), Balsam Fir, Tamarack (larch), poplars (Trembling Aspen, Balsam Poplar), birches (White Birch, Swamp Birch) and small pockets of Eastern White Cedar.

Two sections of the province are not dominated by forest. The province's northeast corner bordering Hudson Bay is above the treeline and is considered tundra. The tallgrass prairie once dominated the south central and southeastern parts including the Red River Valley. Mixed grass prairie is found in the southwestern region. Agriculture has replaced much of the natural prairie but prairie still can be found in parks and protected areas; some are notable for the presence of the endangered western prairie fringed orchid.

Polar bears are common in northern Manitoba.

Manitoba is especially noted for its northern polar bear population; Churchill is commonly referred to as the "Polar Bear Capital". Other large animals, including moose, white-tailed deer, black bears, cougars, lynx, and wolves, are common throughout the province, especially in the provincial and national parks. There is a large population of red sided garter snakes near Narcisse; the dens there are home to the world's largest concentration of snakes.

Manitoba's bird diversity is enhanced by its position on two major migration routes, with 392 confirmed identified species; 287 of these nesting within the province. These include the great grey owl, the province's official bird, and the endangered peregrine falcon.

Manitoba's lakes host 18 species of game fish, particularly species of trout, pike, and goldeye, as well as many smaller fish.
