Canadian Biomes
Canada can be organized into four biomes: A biome is a collection of ecosystems that are similar or related to each other, usually in the type of plants they support. Canada can be organized into four biomes: The Tundra Biome The Boreal Forest Biome The Temperate Deciduous Forest Biome The Grassland Biome
The Tundra Biome Canada’s northernmost biome Is a cold desert- receives only 10 to 12 cm or precipitation per year Abiotic factors: very low temperatures for most of the year short growing season permafrost layer beneath the soil (a layer of soil that never thaws) low precipitation poor soil quality
Communities: rapid-flowering plants mosses and lichens Caribou Rock ptarmigan (a bird that lives permanently in the tundra biome) lemmings arctic foxes wolverines (Hugh Jackman?)
The Boreal Forest (or taiga) Biome immediately south of the tundra biome where the permafrost ends, the boreal forest begins dominated by conifers (trees with needle-shaped leaves; are adapted to harsh environments) the climate is harsh, with many rapid changes in temperature
Abiotic factors: warmer than tundra (no permafrost) changeable weather the soil contains some water and is acidic precipitation is 40 cm/year or more
Community: coniferous trees seed-eating birds squirrels voles snowshoe hares deer pine martens (small carnivore) grey wolves
The Temperate Deciduous Forest south of the boreal forest, in Eastern and central Canada dominated by deciduous trees, such as maples and oaks Abiotic factors: longer growing season higher temperatures fertile soil precipitation up to 100 cm/year
Community: deciduous trees shrubs, ferns tree and ground squirrels insects shrews, mice deer black bears woodpeckers weasles wolves
The Grassland Biome extends from eastern Manitoba to the Rocky Mountains similar to the deciduous forest biome, but receives less moisture than deciduous forest biome Abiotic factors: longer growing season higher temperatures rich, fertile soil precipitation from 25 to 75 cm/year
Community: grasslands grasshoppers bison voles, mice snakes hawks wolves
