Hudson Plains

From Ecozone-Experts, the free school-project-that-imitates-Wikipedia

This section is about the Hudson Plains. For more information, please see Hudson Plains 2.

The Hudson Plains are an ecozone in Canada. The plains boarder Hudson Bay and James Bay and reach from Nunavut and Manitoba to Quebec. It contains one of the largest wetlands in the world and is a host to many spieces despite it's harshness. The eco-zone is scarcly populated, but is threatened by the lumber industry.

Landforms


The rock in the Hudson Plains is composed of sedimentary rock over a worn-down layer of the Canadian Shield. The area formed when the shield was worn down to a point where various waterways could deposit sediment ontop of the rock. This sediment was compressed into a thick layer if sedimentary rock ontop of the old shield. Later, the waters that originaly deposited the sediments wore away the land, creating little riverbeds and such. Later, peat accululated to create the bogs and swamps that plague the northern area.

Climate


The climate of the Hudson Plains are quite similar to that of the maritimes. They consist of cold long winters (average -17 C) and short, cool summers (average 14 C). The amount of precipitation varies from year to year; however, it will always be between 400 and 700 millimeters.

There are two major airmasses that affect the Hudson Plains. The Continetal-Arctic (cA) air mass affects the north-western area of the Plains, while the Maritime-Arctic (mA) affects the south-eastern side. The Continetal-Arctic air mass comes down from the Northwest Territories- the Maritime-Arctic air mass is pulled down from Hudson Bay.

Rocks and Minerals


The rock in the Hudson Plains is composed of sedimentary rock over a worn-down layer of the Canadian Shield.

Even though most sedimentary rock could contain fossils and fossil fuels, the Hudson Plains are devoid of anything to mine. However, if there was something, the area is in too poor condition to mine in. Also, most of the area is under protection by Canadian law.

Vegitation and Soil


The soil in the Hudson Plains is made up primarily of permaforst soil. This harsh, nutritionless soil allows only the hardiest plants to grow and is almost always frozen. The northern-most area of the plains are barren marshlands, called muskeg, while the southern parts are thick, conferous forests. Muskeg is a general term; it represents both bogs, peaty areas that need precipitation to fill with water, and fens, which also contain large amounts of peat but fill themselves with ground water. Fens often have rich aquatic ecosystems with plant-life that serve as wonderful nesting ground, while bog are commonly lack the nutrition needed for life.

The vegitation that grows in this territory is strong. To the north there is emense fields of swamps and little creeks, with bushes and mosses the only plants around. Down south there are large helpings of black spruce and tamarack. The average growing season last about 90-150 days, or 3-5 months. Some of the small plants in the area include red knot, fireweed, eelgrass, lichen and acrtic cotton. The ecozone is a popular nesting and breeding ground for ducks and geese.

Trivia


  • Despite being so barren, the area is home to a veriety of creatures from the red fox to the polar bear to even the baluga whale!
  • The Hudson Plains are the third biggest wetland in the world, right behind the Siberian Wetlands and the Amazon Floodplains.
  • The ecozone is very hard to live in, so the human population is few. However, it is a beautiful place to camp and explore (which is one of the Hudson Plains' main industry). Despite the lack of population, human activity is not something in which this area lacks!

Questions


To view the answers, highlight the box below.

1. True or False: The Hudson Plains is made up entirely of swamps and bogs.
2. The Hudson Plains is under government protection so that the area may be protected from deforestation, yet they still allow camping and water sports in the area. How does this effect the enviorment and what is your opinion on this?
3. Which ecozone(s) does the Hudson Plains resemble and why?
4. True or False: On average, the growing season in the Hudson Plains lasts about seven months.
5. This ecozone lacks the nutrients to support an extensive ecosystem, yet in some areas many spieces thrive. Why is this?

1. False. The Hudson Plains contain both wetlands to the north and tagia forests in the south.
2. Your opinion- no answer.
3. The ecozone resembles the Atlantic Maritimes because of the similar airmasses, and the southern Artic because of similar location and similar airmasses.
4. False. It lasts anywhere from 3-5 months
5. Because of where the area gets it's water and trhe amount of peat in the area.
