The northern section of the Alaska subrealm, located in the Subarctic America (Nearctic) realm, is delineated by the Brooks Range. The North Alaskan Tundra bioregion is entirely made up of three tundra ecoregions—Arctic Coastal Tundra (407), Arctic Foothills Tundra (408), Brooks-British Range Tundra (411)—including the adjacent marine areas of the Beaufort and Chukchi seas. The total land area of this bioregion is 34 million hectares. 

The North Alaskan Tundra bioregion is part of the Alaska subrealm and is made up of three ecoregions: (1) Arctic Coastal Tundra (2) Arctic Foothills Tundra (3) Brooks-British Range Tundra.

One Earth is dedicated to mobilizing philanthropic capital to protect the ecosystems and peoples of Subarctic America. Visit the Project Marketplace to explore projects in this realm that need your support. Learn more about each of the North Alaskan Tundra ecoregions below.
