Transcript Canada`s Natural Vegetation

Canada's Natural
Vegetation
Canada has over 140
species of trees, and its
forests cover more land
then almost any other
country's.
Tundra
• Has minimal vegetation cover.
• Artic climate
• Short growing season
• Has permanent frozen soil - thaws long
enough in the summer for a few mosses,
lichens, low bushes and Artic grass and
flowers.
•The tree line separates the tundra region
from the boreal forest region
• Small amount of wildlife.
Boreal Forest
•A huge region and the largest vegetation zone in
Canada.
• This region's forest rivals those of Siberia in
their vastness and mainly are coniferous.
• Coniferous trees (evergreen or softwood) are
cone bearing trees, triangle shaped , and have
needle like leaves.
• The trees of the boreal forest region are
specially
adapted to withstand severe
climatic conditions and often poor soil
conditions
Deciduous Forest
•It is the smallest of Canada's vegetation
regions. • It's found in southern Ontario.
• The deciduous trees in this region grow larger
then the Boreal forest.
• Deciduous trees (hardwood) are round in
shape
and have large thin broad leaves, which
fall in the fall.
• So much of this forest have been removed.
This has caused the disappearance of the larger
animal species who once lived in this region
and depended upon it's trees for cover.
Mixed Forest
•Mixture of coniferous and deciduous
forests.
•The mixed forest and deciduous regions
are part of or close to the most densely
populated
part of Canada, therefore
many portions of the vegetation has been
removed.
Mountain Vegetation
• Because of varied climatic conditions in the
cordillera, there is varied vegetation in this
region. Vegetation changes as the elevation
increases.
• Because much of this regions natural forest
still remain, wildlife is abundant in this
region.

Grasslands
• Found in the southern Prairie provinces.
• Grasslands are the results of the conditions
fostered by the semiarid Prairie climate
region. It is too dry for trees.
• In the central and southern portions of the
region (the driest area) the sparse vegetation
is like that of a semidesert, and includes
cactuses and sagebrush.
• Toward the moister areas the grass becomes
higher. Here most of the grain production
takes
place.
West Coast Forest
• The coastal areas of B.C. have high
precipitation and moderate temperatures, so
under these conditions it is possible for very
large coniferous trees to grow.
• The dense forest of huge trees along
Canada's west coast are sometimes referred
to as a temperate rainforest.
