In this ecosystem it can get as low as -25 degrees Celsius. The average precipitation is 3 centimeters. The average temperature is 0 degrees Celsius to 25 degrees Celsius.
There is one similar area and it is the Yellow Stone National Park. Because it has much of taigas (forests) in some areas.

Abiotic Factors In The National Wildlife Refuge:
One abiotic factor in The National Wildlife Refuge is snow. The snowfall will shape the tundra landscape. The extreme cold creates a layer of premently frozen soil called permafrost. When the snow melts everything becomes flooded with a lot of water because it can't drain through the permafrost.
Another abiotic factor in The Arctic National Wildlife Refuge is the ponds. During the summer on the coastal plain of The National Wildlife Refuge it is pitted with ponds and other small bodies of water. Most of the 19 million acres is wildlife and tundra. But as the permafrost freezes and when it somewhat melts over the tundra, it creates much water and ponds.

Human Factors in The National Wildlife Refuge:
One human factor in The National Wildlife Refuge is the oil drilling. People have been debating since about 1969, to whether or not drill oil out of the northern part of the coastal plain. They predict that there is much oil; but aren’t sure if they should drill it because of the habitat. In 1980, they ended up drilling for the gas and oil. The congress had made the decision and allowed the drilling to happen.
Another human factor in The National Wildlife Refuge is seismic exploration. People had drilled for oil and gas, and then fifteen years later…there are still scars that can still be seen. Also during seismic exploration activities, vehicles compacted the snow and damaged underlying plants.

retrived on 5-25-12It is often described as an evergreen shrub with woody, irregular, reddish branches with delicate white flowers.
The size can range from 2 meters tall.
Lemmings live near stream beds, meadows, and underground chambers. They eat grass and moss in the summer. Then eat bark and twigs in the winter. The predators for a Lemming are owls, ravens, weasel, minks, lynx, arctic foxes, and wolves. When the lemmings are over populated they get nervous and commit suicide.

They need to live near water to survive. They use dry grass to hide and to build nests. The people are drilling for oil near the refuge. Which destroys their habitat.
One secondary consumer is the caribou. It lives in open areas, semi open tundra, and taiga. It eats lichen, moss, leaves of shrubs, grass, and forbs. What eat the caribou are wolves, bears, wolverines, and lynx. In winter, it lives in taiga conifer forest.
It creates well-worn trails during migrations.
Roads and development easily disturb traditional migration routes. Hunting has weakened or eliminated many southern herds.
