Hudson Plains Ecozones
Transcript of Hudson Plains Ecozones
- The Hudson Plains cover about ¼ of Ontario and 4% of Canada (369 000 Square kilometers of land and 11 800 Square kilometers of water).
- The Hudson Plain is drained, flat and dominated by covering wetlands. Location Of The Hudson Plains Hudson Plains Wildlife - Many species in the Hudson Bay region are losing fat and body mass.
- The floating sea ice melts faster.
- Polar bears are likely to go extinct in the next three decades.
- Global warming melts Arctic ice faster.
- This reduces opportunities for hunting.
- They need to build up enough fat in the winter to get through the summer.
- When the ice retreats from the shore the bears lose the opportunity to hunt.
- The ice is melting earlier in the spring and forming later in autumn.
- The bears are spending on average three extra week without food than they did three decades ago.
- If they don’t store enough food then they die.
- The consequence of this is they are diminishing faster as global warming continues.

By, Caroline, Gillian, Hasti, Rachel Climate -The Hudson plains covers 3,6% of Canada's area
- Sandstone is very rare.
-This eco-zone is known for its low-lying, swampy plains.
-Ever since glaciation, the flat landscape, along with other factors such as poor drainage has helped the wetlands develop. Hudson Plains Economy - GDP: $0.1 billion
- POPULATION DENSITY 2001: 2.65 people / 100km2
- POPULATION: 10 000 people (0.4% of Canada’s population)
- SIZE: 4% of Canada (432 000 km2)
- HBC: Hudson bay company set up forts for trade
- ECOLOGICALY DIVERSE
- ECONOMIC BASE: fishing, trapping, hunting, tourism
- IMPORTS: (we couldn't find anything)
- EXPORTS: fish
- COMUNITIES: Moosonee, Ont. Churchill, Man. 1.Canada Geese
2.Lesser Snow Geese
15.Moose Antler Churchill, Manitoba receives an average of 264 mm of rainfall per year. However, the average of the Hudson plains is between 400-700 mm Churchill, Manitoba is a major city found in the Hudson Plains The average temperature in Churchill is approximately -7 degrees, though the average temperature of the entire area of the Hudson Plains eco-zone is approximately -17 degrees in the winter and 14 degrees Celsius in the summers. -The climate in the Hudson plains has very long, cold winters and short brief summers. This is because it has a subarctic climate.
- Many rivers found in the Hudson plains can cause floods in the summer months, that often rise to 10-15 m.
- Temperature is very cold, and frost-free periods last no longer than 70 days.
-The growing season varies from 90-150 days per year. Landforms Landforms- Major Rivers - The Nelson and Hayes in Manitoba,
-The Severn, Winisk, Albany and Abittibi in Ontario
-The Eastmain and La Grande in Quebec Hudson Plains Canadian Geese Lesser Snow Geese Northern Pintail Tundra Swans Fireweed Eelgrass Lichen - The Vegetation in the Hudson Plains is very strong.
- To the North there are fields of swamps and little creeks, with bushes and mosses the only plants around.
- Down South there are large amounts of Black Spruce and Tamarack.
- The average growing season lasts about 90-150 days (3-5 months).
Some of the small plants in the area are:
- The Hudson Plains is made up of premaforst soil.
- The Nutrition less soil allows only the hardest plants to grow and is almost always frozen.
- The North area of the plains is are the barren marshlands, called Muskeg.
- The Southern parts are thick, conferous forests.
