Tundra
  • Coldest biome.
  • Growing season short.
  • Simple vegetation that can resist climate Low
    shrubs, sedges, moss, grasses and flowers
  • Soil takes a long time to form.
  • Located Arctic NorthLinks http//www.thecultur

Taiga Forest
  • Harsh continental climate
  • Large temperature range between summer and winter
  • Long winters
  • Low precipitation
  • Poor soil
  • Closely-spaced trees and mossy ground cover.
  • Larch, spruce, fir and pine coniferous
    treesLocated Canadian ShieldLinks

Boreal Forest
  • Occupies 77 of Canada's total forest land.
  • South of the taiga forest, but very similar.
  • Sweeps across North America.
  • Lots of coniferous trees.
  • Often called the spruce-moose biome.
  • Located S. Canadian Shield, Northern

5
Plains
  • 95 of the plains has been converted to farmland.
  • Alteration of natural habitat has meant more
    endangered species on the prairies than anywhere
    else.
  • Located Prairies

6
Montaine
  • BC has several forest zones due to its
    fluctuation mountain climate. On the coast,
    there is a coastal rainforest in the mountains,
    a montaine climate.
  • Older forests mostly coniferous, younger forests
    are mixed.
  • Due to the varying altitude (height) of the land,
    there is a mix of alpine, tundra, and taiga
    forest.
  • Located British Columbia, Western Alberta


7
Coastal Temperate
  • Lots of mountains, leading to lots and lots of
    orthographic rain... leading to really really
    big, really really old trees.
  • Rarest ecosystem in the world (.02 of earth
    surface)
  • Mix of deciduous and coniferous forests in some
    areas, but oldest areas are deciduous.
  • Trees are so big that almost nothing can grow on
    the floor due to no sunlight.
  • Located Pacific Coast


8
Mixedwood
  • Less than 3 of this forest remains.
  • Urbanization and agriculture have reduced the
    ancient forests.
  • There was a mix of coniferous and deciduous
    trees, with MANY native coniferous trees.
  • Lots of good soil and water.
  • Located Great Lakes/St. Lawrence River

Atlantic Maritime
  • Most of this forest is gone after centuries of
    farming.
  • Inhospitable highlands make for acidic soil. Poor
    for farming but decent for forests.
  • More storms than anywhere else in the country.
    Lots of precipitation.
  • Almost all of this forest has been logged at
    least once, meaning no really old trees.
  • A tree disease killed off most of the chestnut
    trees in the 20th century.
