Hudson Plains

Landforms: The landforms in the Hudson Plains are low-lying and swampy plains. The Hudson plains stretch from Manitoba to Quebec along the Hudson Bay. The terrain here is flat, and the poor drainage encourages the creation of wetlands and bogs. Palaeozoic and Proterozoic sedimentary bedrock slopes gradually towards the Hudson Bay. The Hudson Plains is almost a quarter of Ontario in size and covers 369 000 square kilometers of land and 11 800 square kilometers of water.

Climate: The climate in the Hudson Plains is moderately long, cold winters (-17C), moderately short, cool summers (14C); precipitation 400 + 700mm, growing seasons 90 to 150 days. The Hudson Plains Ecozones poor drainage had resulted in the largest continuous wetlands in the world. Hudson’s Bay moderates the temperature in summer, but the ice that covers it in winter prevents most of this; average summer temperature is -18C. Precipitation ranges from 400mm in the northwest to 800mm in the southeast.

Wildlife: Some examples of wildlife in the Hudson Plains are polar bear, black bear, moose, and arctic fox. Predators such as lake sturgeon, brook trout, northern pike, and walleye prey on such species as Lake Herring, Lake Whitefish, Lake Chub, pearl dace, and ninepin stickleback. Three frog species that live in Hudson plains are the striped chorus frog, northern leopard frog, and the wood frog. Waters: Bays in the Hudson Plains are; Hudson, James. Rivers in the Hudson Plains are; Nelson, Albany, Severn.

Vegetation: The vegetation in the Hudson Plains contains ground-hugging tundra; increasingly dense forest in south (white spruce, black spruce, tamarack, jack pine).Soils: The Hudson Plains has scattered permafrost occurs; poorly developed organic and permafrost soils. The soils in the Hudson Plains are leached and not calcified.

Human activities: The GDP in the Hudson Plains is GDP $0.1 billion; hunting, trapping, recreation. A lack of timber and minerals means that tourism and subsistence activities are the means by which the people who live here make their living. Every winter, people gather around to watch and observe the polar bears that live in the area. Because of this, many tourists are attracted to the Hudson Plains in the winter.

Major cities: Major cities in the Hudson plains are Moosonee (1939), Churchill, and Attawapiskat. The Hudson Plain is a small Ecozone which does not contain many populated areas.Population: The population in the Hudson Plains is around 10,000 people (2.7 people per 100 square kilometres).
