Oil wells take over habitat. Pollution seeps into habitat.
Plants with such a short season can't take human disturbances.
Plants that make their own food.sedgehttp://www.extension.umn.edu/projects/yardandgarden/yglnews/yglnewsmar12008.html
Sedge lives by bogs, swamps, ponds, streams, and wetlands. Its food is produced by photosynthesis. Deer, elk, caribou, reindeer, musk ox, bears, rabbits, hares, small rodents, and ground-nesting birds. Sedges look like grass, but are in a different family. A way to remember this is that sedge stems have edges, and grasses are round. With such a short season it takes many years for the sedge to repair its self from human disturbances.

The consumers that eat the primary consumers.least weasel http://en.wikipedia.org/wiki/Least_weasel 5-29-12
The least weasel lives in open tundra, meadows, and fields; brushy edges of marshes and streams. The predators of the least weasel are larger weasels, domestic cats, snakes, lynx, and bears. The least weasel's prey are mainly rodents, including rabbits, hares, lemmings, voles, shrews, and other small animals that don't hibernate during the winter; may eat insects and amphibians during the summer. Because of their size, least weasels often chase rodents into their burrows to catch them. The females may breed several times in one year if food is plentiful.
