The Aleutian shield fern is a plant species that have been endangered due to caribou tramping and grazing, slumping from growing substrate, and human foot traffic. [9] Animal species that are endangered in the tundra include the Arctic fox, caribou, and polar bears.
This region provides calving habitat for four herds of caribou, the Western Arctic, Teshekpuk, Central Arctic, and Porcupine caribou herds. Another key species is the muskox of Banks Island and the Arctic National Wildlife Refuge coast.
Boreal ecosystems are filled with a multitude of flora species from black and white spruce, to willows, wildflowers, and alders. [6] Caribou, although not there year round, come down and into these regions during the winter to forage for lichen. [7] A few fish species include salmonids, smelts, sticklebacks, lamprey and sculpins. [8]

The water in this region is generally frozen and evaporation rates are very low. Species diversity, nutrient availability, precipitation, and average temperatures increase as the landscape progresses from the tundra to boreal forests and then to deciduous temperate ecosystems, which are found south of the Arctic biomes.

The slopes are covered with a variety of lichens and other tundra plants, depending on altitude and drainage. The low-lying, wetter areas are similar to the surrounding Beringia lowland tundra ecoregion but the uplands are generally drier and dominated by sedges such as Eriophorum vaginatum and scrub such as the ericas Arctostaphylos alpina, Vaccinium vitis-idaea or Empetrum nigrum or mountain ...
This is a hilly area that lies between the boggier Arctic coastal tundra to the north and the Brooks Range to the south, and stretching from the Chukchi Sea east across northern Alaska to the border with Canada's Yukon Territory. The Noatak River valley is the only forested area. [2]
