Arctic National Wildlife Refuge Anabella, Wendy, Lookman, and Aidan Introduction Welcome To: Arctic National Wildlife Refuge Introduction The Arctic National Wildlife Refuge is considered as a middle arctic tundra. It’s also an ecosystem. It is in the northeast corner of Alaska and covers 19 million acres. To the south of the Arctic National Wildlife Reserve is the Brooks Range. To the north, it’s the Arctic Ocean. Biomes Of The Arctic National Wildlife Refuge 4 Biomes • The Arctic National Wildlife Refuge covers 7,700,000 hectares which is at least 19 million acres. • The ecosystem also known as the Artic Tundra has/contains treeless landscapes and very flat land. This biome is a specific type of Tundra-Arctic. This means that it is probably around the North Pole area. The Arctic National Wildlife Refuge receives at least 4 Inches of precipitation every year. Also the areas in the biome is still wet due to the ice melting. Abiotic Slides All So Important In The Arctic National Wildlife Refuge Abiotic This ecoscenario is very cold and snowy, this is what forms the tundra there. Also, all this snow helps the animals in one ways because for one it can protect them from the cold winds. Another way that the conditions in this ecoscenario affect the animals is that the snow allows them to make tunnels in it to hide from predators. In this ecoscenario there isn’t much precipitation, there is on average there is 15-25 centimeters of precipitation The average temperature in this Eco scenario is 3654*F and is 1830*F in the winter As said before the weather here is very cold and it’s very icy, rather than snow there is more ice there but when It does snow it stays that’s why there is lots of it The climate there is very wet and cold and the temperature is usually around 5 degrees Celsius Date & Time Chart Date Time Jan,21st 2h, 22mins, 36s Feb,21st 8h, 21mins, 01s Mar,21st 12h, 32mins, 22s Apr,21st 17h, 20mins, 21s May,21st Up all day Jun,21st Up all day Jul,21st Up all day Aug,21st 17h, 10mins, 28s Sep,21st 12h, 27mins, 48s Nov,21st 1h, 46mins, 04s Dec,,21st Down all day Biotic Slides Discovered In The Arctic National Wildlife Refuge • Grasses and sedges form in protective clumps called tussocks and shrubs like willow and Labrador Tea. • The main producers are reindeer lichen, cotton grass, Labrador tea, sedges, and willows Biotic (Animals) The main predators that are found are the (arctic) foxes and wolves. The musk oxen work A wolf pack will kill 11–14 Arctic foxes are well together by huddling caribou annually, usually adapted to live in the cold together for protection during migration or in winter and don’t need to from predators and from and will attack musk oxen hibernate in winter.

Many birds migrate to the Arctic National Wildlife Refuge during the short summer periods. Geese Snowy owls are secondary consumers in the Arctic National Wildlife Refuge. They usually get eaten by lynxes and flies feeds on their blood. They, however do not migrate like some birds do.

A developed oil field can have drilling platforms, plumbing and sewage pipes and housing for the workers on the plant. That causes a lot of pollution all on its own. http://en.wikipedia.org/wiki/Tundra http://www.fossweb.com/ http://timeanddate.com
