Arctic coastal tundra

WWF Abstract

The entire Arctic Coastal Plain is important breeding and calving ground for many species. Three major caribou herds, the Western Arctic, Central Arctic, and Porcupine, migrate here each year to have their young, and many species of shorebirds and waterfowl such as snow geese, spectacled and steller's eiders, king eiders, and yellow-billed loons come here every summer to breed. Permafrost, a thick, unbroken layer of ice lies underneath the ecoregion. Water that melts on top of the permafrost collects into what are called thaw lakes, of which this area has many, covering nearly 50 percent of the ecoregion. Wetland vegetation is common, dominated by sedges and grasses, and there are small raised peat mound bogs or marshes along the coast. Mosses and lichens almost entirely blanket wet soils.
