Arctic Cordillera Ecozone
Transcript of Arctic Cordillera Ecozone
Arctic Cordillera Landforms Landforms and Climate The Arctic Cordillera has long winters with an average temperature of -40 degrees Celsius and short summers with an average temperature of 0 degrees Celsius. The Arctic Cordillera has little precipitation; less than 200mm and almost no growing seasons. The precipitation is predominantly snow since the temperature is less than 0. In the Arctic Cordillera there are many different types of landforms, some of which include:
- calved ice from glacier
-raised beach There is very little to no soil in the harsh climates of the Arctic Cordillera. There is mainly rock and ice covering the ground, and glaciers freeze the soil very deep in the ground making it even harder to defrost. It is almost impossible to find any minerals in the soils because of the permafrost and cold weather, but there are many forms of igneous, metamorphic and sedimentary rocks in many places, usually close up in the mountains. -arctic black spruce
-arctic heather There are rarely any mammals in the Arctic Cordillera, and the birds will leave to fly south when the weather gets unbearable. However, these animals have thick layers of fur and fat to keep themselves warm. These animals include:
- Thick- billed Murre - Common Eider
- Black Guillemot - Beluga whale
- Polar Bear - Snow Bunting
- Arctic hare -Hoary Redpoll
- Arctic Fox - Northern Fulmar
- Ermine - Common Ringed Plover
- Collard Lemming - Snow Bunting
- Little ringed Plover - Ringed seal
- Walrus The human economic activity in the Arctic Cordillera are mainly hunting, trapping and fishing. Since there is little to no precipitation and the fertile land, agriculture is near to impossible. The Inuits, the people who live in the Arctic Cordillera, rely on hunting, trapping and fishing to support their families and bring income into the community. Tourism also helps bring in money since the beautiful landscapes are hard to miss. The GDP is $0.012 billion and only about 1,000 people live in the Arctic Cordillera. Bibliography "Canadian Biodiversity: Ecozones: Arctic Cordillera." Canadian Biodiversity: Ecozones: Arctic Cordillera. N.p., n.d. Web. 06 Feb. 2013 The Arctic Cordillera is too cold for many plants to grow. since three-quarters of the land is bare rock, many moss species including lichen have a hard time growing. also, because of the low amounts of precipitation, and the frequent and sudden frosts, it makes it difficult for the plants to continue to grow. some plants do survive this cold, harsh weather by covering themselves inside rocks and holes of the mountains to keep them hidden from the winds. some of the plants that can be found are: "Arctic Cordillera Ecozone."

Clyde River, Nunavut is a place where many Intuits live in. Their community revolves around hunting, fishing, and trapping. One impact that these people have on the environment is hunting and trapping. Hunting and trapping can affect the environment because it takes the animals away from their habitats and away from their natural predators. Taking part of the food chain away can cause their prey to produce even more and their predators to decrease in population. It makes the balance of the ecozone to be disrupted. Another impact on the environment is fishing. When people fish, their predators would decline in population since they don’t have the amount of fish to keep them alive, allowing the population of fish to grow and people having the tenancy to fish even more. This causes disturbance in the biodiversity in our ecosystem. The third impact they have on their environment is little transportation meaning less pollution than here in Toronto, Ontario. Since their main way of transportation is not by a vehicle, they produce less pollution from non-point source pollution. Although there might be other pollution sources, they can count out cars and vehicles. When they don’t drive much, it cuts the amount of pollution in the air and keeps the air clean for everyone and every animal. A future change that would be created by these impacts it the amount of food sources in their environment since their main income is from trapping, hunting, and fishing. Although they may be giving back to the environment by keeping the air clean, they are still taking away the fish and animals for food, and sometimes fur. I think that as technology increases, the Intuits will eventually use those sources from technology to increase their employment rate so that not all families are depending on hunting, fishing, and trapping. As they move onto the technology side, their production of cars and vehicles will increase causing more pollution.
