Interior Plains
By: Sammy
Hello, today I am going to be talking to you about the Interior Plains. The Interior Plains is made up of parts of 6 provinces: Yukon, Northwest Territories, British Columbia, Alberta, Saskatchewan and Manitoba. The Interior Plains are mainly flat, dry, grassy lands. There are also areas with oil sands, forests and agricultural crops. This region is called the land of the open sky. It gets that name because the sky is so easy to see because the land is so flat. The Interior Plains is located between the Cordillera region to the west the Canadian Shield to the east.
Food Chain and the Habitat
Lands, Cities and Regions
The food chain I looked at was located in southern Interior Plains. The food chain I found in that region was made up of three animals and vegetation. The Ferruginous Hawk (consumer2 or top of the food chain) would eat the prairie dog (consumer1) and the prairie dog would then eat any sort of grass or plant (producer) it can find, but then when the ferruginous hawk dies the worm (decomposer) eats its remains and returns nutrients to the soil. The biggest environmental problem that has happened to the animals of the Interior Plains is farm pollutants. These pollutants are seeping into the ground and/or running off into the rivers and lakes. Pollution from automobiles, disposing waste into landfills and excessive lumber harvesting also negatively affect the Interior Plains. Farmers are working to conserve the habitat of the Interior Plains by rotating crops to allow the land to recover nutrients and using planting techniques that minimize soil erosion. This makes more land and food available for animals. The Interior Plains is important to people for agriculture, forestry, oil, gas and minerals.
- As you know, the Interior Plains is made up of 4 provinces and two territories: BC, Alberta, Manitoba, Saskatchewan, Yukon and NWT.
- The main cities that are in those provinces are Calgary, Edmonton, Saskatoon, Regina and Winnipeg
- There are three regions located in the Interior Plains: The Prairies, The Boreal Plains and the Taiga Plains
- The Interior Plains make up 18% of Canada's land surface or 1.8 million square kilometers
- Unique landforms in the Interior Plains include: the Mackenzie River, Cypress Hills, the Badlands, Great Bear Lake, Great Slave Lake Lake Winnipeg and Lake Athabasca
Forming of the Interior Plains
The Interior Plains were formed from inland seas, mountain building and glaciation. Approximately 545 million years ago, the Interior Plains were covered with an inland sea. While covered with the water, sediments, plants and animals combined to form today's rich oil and gas fields. During the Pangaea period, 225 million years ago, when the rocky mountains formed, the sand and soil washed off the mountains and covered the Interior Plains creating a gentle down slope from the west to the east. During glaciation, glaciers covered most of the prairies. When the glaciers retreated, they left behind sand, gravel and boulders which became today's farm land. Water from the melting glaciers filled depressions to create lakes and flowing water created rivers.
Cordillera Region:

The mountainous region to west of Interior Plain including BC, Yukon and part of Alberta
Canadian Shield:
Is the rocky region east of the Interior Plains around Hudson Bay including parts of NWT, Nunavut, Manitoba, Ontario, Quebec, Labrador, New Brunswick and Nova Scotia
A decomposer breaks down dead plants and animals to provide nutrients for the earth soil.
Is a animal that eats plants, meat or both
Is a plant that gets its energy from sunlight and is the food for a consumer
Farm pollutants:
Fertilizers and other chemicals which help crops grow or pesticides to control weeds but can be harmful to the land and animals when washed into nearby waterways
The Boreal Plains:
The northern region of the Interior Plains
Taiga Plains:
The area north of the Interior Plains that includes part of Russia
