Boreal Plains Ecozone
Transcript of Boreal Plains Ecozone
Area:668 664 km2
The creation of the Boreal Plains landscape is mainly due to effects of continental glaciation 10 000 yrs ago. The melt water from the glaciers left behind ancient lakes which are present today in the form of deep, wide rivers, deltas and dunes and river valleys which are the main source from where rainwater comes from in the Boreal Plains. The Boreal Plains has a flat and gentle rolling landscape due to erosion and deposition from the glaciation. Although a portion of the ecozone in BC is leveled, this is where the Rocky Mountains are. Underlying these landforms are layers of sedimentary rock. Much of the ecozone is covered by forests (84%) despite of heavy logging activities occurring in most areas.
Physical System Influences
The Boreal Plains have rather long, cold winters with an annual average temperature of -20’C and short, warm summers averaging to 17’C. Precipitation level ranges from 300mm in the West and 625mm in the east. The Boreal Plains has a dry, continental climate. Which best suits agriculture, because calcification occurs. Growing seasons ranges from 130--165 days each year.
The dry climate are causes for forest fires, which has the greatest impact on the Boreal Plains forests. In a year, on average, more than one million hectares of land are burned despite efforts made trying to prevent them.
Due to the low evaporation rate the ecozone hold, the soil is constantly wet though the climate is dry, this helps greatly on farming because with the help of calcification pushing all the minerals obtained from the parent material to the plants above, making growing conditions ideal.
-The pace of logging increased in 1956 when technology in Alberta created the first pulp mill, and over the years between 1951-1991, the damages made to the environment due to logging has increased by 82%. It has reduced many population and biodiversity as well as habitats for species.
-The Boreal Plains holds the largest source of fossil fuels in Canada due to the layer of sedimentary rock underneath 'which turns in fossil fuel. While exporting, bodies of water suffers from pollution due to oil leaks while shipping which increases the death of aquatic species and less drinkable water, oil and gas exploitation also increases habitat loss and species are harmed due to toxic farm run-off. These are major problems in the Boreal Plains.
Wood Buffalo National Park
In the Canadian history, the Boreal Plains’ was an ideal place for fur trade to take place, which had the biggest impact on this ecozone. Bison were killed for both food and their hide. Thousands of bisons were killed each year and sold to the North America and Europe’s fashion industry, that by the 1880s, the bison population was rapidly decreasing to the amount where they were almost extinct.
Boreal Plains Ecozone
The Boreal Plains ecozone is located in the regions of the Interior Plains.
Boreal Plains found in :
- center of Alberta
- center Saskatchewan
- Southern Manitoba.
-small portion of eastern BC
-small portion of southern NW territories
The Rocky Mountains

On the Ecozone
¾ of a million of people live here. Scattered over the plains in small communities rather than clustered populations like it would be in urban areas.
The main source of income in the Boreal Plains Ecozone comes from:
-oil and gas exports
The soil type in the Boreal Plains consists
mainly of luvisolic soil. This soil type is dominant
in areas that's heavily forested and the landforms
below underlies layers of sedimentary rocks and is grey in colour. The parent material of this soil type is rich in calcium and magnesium. This, might be the result of acidic soil in some areas of the Boreal Plains, especially the east. The ecozone has a low evaporation rate, meaning the soil stays wet even though the climate is dry.
Reasons for dry climate:
-no large bodies of water close
by, main water source: rivers
-Rocky Mountains casts rain
shadow over the west side of the
All 4 of these industries are highly destructive as big areas of land are cleared. The government have been trying to find methods to continue these industries without creating irreversible damages to the environment.

The Rocky Mountains on the west side of the ecozone greatly affects the climate; casts a rain shadow over the land on its east, which blocks most of the moisture in the wind from traveling to the west of ecozone. This is the main reason as to why the western parts of the ecozone, is even more dry than the east side.
The Boreal Plains consists both of
coniferous and deciduous trees; deciduous
to the north and coniferous to the south.
Some examples are white and black spruce, aspen and
poplar, birch exists in some areas.
-Long, cold winters
-short, warm to

The sedimentary rock (parent material) below the landscape holds excellent minerals for growing crops and supporting the large forests in the ecozone.

A large number of areas are located in this ecozone. E.g. The Wood Buffalo National Park was established in 1922 and has an area of about 45 000 km2, and is currently Canada's largest national park. The point of it was to save and preserve the lasts of the living wood bisons, And not just bisons live in this ecozone. so does the whooping cranes, the large amount of wetland in the area is the only nesting place left for them in whole world. The park was declared as a world heritage site in 1983
