Ecozones are regions that are
divided by the type of
land and how the living things in these regions use them. Ecozones help
classify places using infomration like climate, GDP, population and
much more. In British Columbia there are three dominant ecozones. These
ecozones in order from least significant (size) to most significant
are: Montane Cordillera, Pacific Maritime, Boreal Cordillera. The
Boreal plains as well as the Taiga plains also cover a very small area
of British Columbia.
Area And Climate
The Montane Cordillera is the largest ecozone in
B.C. with 461000km2 of land and this land conists of Mountains, plains
plus Plateaus. The Climate of the Montane Cordillera allows a pretty
good amount of growth. With moderate winters and a pretty warm
temperature of 15ºC, there is no doubt that there will be a large
amount of precipitation. This is true, there is about 500mm to 1000mm
of precipitation and the growing season is usually 140-240 days.
In this ecozone there is some variety of trees,
although most forests are composed of Coniferous trees. There are also
Engelmann spruce, Ponderosa pine and Douglas Fir trees.
learning about the various amounts of vegetation, it can also be
determined that there are a various amount of soils.
The total population of this ecozone is about 452
000 people. These people also produce 14 billion dollars a year. The
main industires include Forestry, Agriculture, and tourism. The
Montane Cordillera is a rather significant ecozone to the province as
it has a large population and provides a large sum of money
(14billion). There is a strong correlation between population and GDP
in ecozones. When the population is high, the GDP is high. When the
population is low, the GDP is low. This is because there are more
people driving more cars
which has a higher sum of money. There are also more people earning
more salaries which adds to the GDP.
Area And Climate
The Pacific Maritime Ecozone is only located in the
province of B.C. and it is 196 000km2. This ecozone is made up of
Mountains and small areas of coastal plains. The winters are very
mild and remain at about 3 celsius although the summers are rather
moderate and remain at 15 degrees celsius. This climate is mainly
caused by the Moderating Effect of water. The winter is warm because
the water is still warm from summer and it heats up the land. The
summers are cool because the water becomes cold and cools off the land
in the summer. Due to the climate there is a lot of evaporation and
therefore a lot of precipitation. There is about 600-2000mm of
precipitation per year and the growing season lasts 200-260 days.
The vegetation in this ecozone contains a vast
variety of large trees but once again mainly coniferous trees. There
are also western red cedar trees, Douglas fir, western hemlock,sitka
and spruce trees. This large variety of trees is caused by the large
variety of soils. Due to the great amount of rainfall there are larger
trees in this ecozone then most other parts of Canada. There are
various trees and soils in this ecozone.
This is a rather crucial ecozone to B.C and all of
Canada’s economy. About 60 billion dollars is produced annualy. This is
because of the huge population of people which is around 3 million.
This ecozone in B.C also has a huge amount of urbanization that takes
place and therefore there are many buildings with large values that add
to the GDP of this ecozone.The main industries are forestry,
urbanization, agriculture and fishing. The major cities are Vancouver
Boreal Cordillera Ecozone
The Boreal Cordillera ecozone is mainly in the north
west corner of British Columbia. The total area that this ecozone takes
up is about 432 000km2.This ecozone is completed with Mountains and
some hills. The climate of this ecozone is mainly effected by latitude
because the location of this ecozone is in North British columbia. The
heat from the sun is less concentrated and therefore there are long
cold winters at about -21celsius and short cool summers of about
12celsius. Therefore due to this cold climate there is a limited amount
of precipitation. This is because when it is cold the air is thin and
therefore the air can’t hold a lot of precipitation. Due to this,
preciptitation can’t gather and thats why there is a small amount of
precipitation. There is about 300-500mm of precipitation every year and
the growing season is short and lasts 125-150 days.
It is obvious that because of the lack of
precipitation there will be a lack of vegetation. In this case it’s
true and this is justified because in this ecozone there are only three
types of trees. Coniferous trees, White spruce and subalpine fir trees.
Although there is a limited variety of trees there is still a large
variety of soils.
With GDP , the rule is that with a larger population
there will be a bigger GDP. This is definately eveidence in this
ecozone. There are amazingly, only 16 000 people on this ecozone.
Therefore the GDP stands very low at only 0.9 billion dollars. The main
industries are hunting, trapping, forestry, tourism and mining. There
is a small population mainly because the weaher is very cold and also
people are moving into larger cities down south. These large cities
have settled down south because they are near large bodies of water (
Great Lakes ) and therefore have better sources of water.
After reading this information we hope that you realize that
classifying ecozones are very imporatant. Geologists or anyone, can
analyze where we are making all of the money and how other ecozones can
match up to these successful ecozones and become larger contributions.
Ecozones classify regions by information.
