Arctic coastal tundra : ウィキペディア英語版 | Arctic coastal tundra
The Arctic coastal tundra is an ecoregion of the far north of North America, an important breeding ground for a great deal of wildlife. ==Setting== This ecoregion is located on the north coast of Alaska, and includes the east coast plain of Banks Island, as well as the Anderson River and Horton River plains, and the Tuktoyaktuk coast in the Northwest Territories. This in an area of low, flat, boggy coastal plains. The underlying soil of this damp Arctic coast is thick, solid permafrost, covered in summer with thermokarst "thaw lakes" of melted ice. Ice features such as ice wedges and pingo mounds of soil and ice can be found. This coast has an arctic climate warm enough to allow plant growth in late-June, July and August only, and even then frosts may occur. On the whole this is a damper, wetter area than the Low Arctic tundra ecoregion that continues along the coast west of here to Quebec.
