Brooks–British Range tundra
The Brooks–British Range tundra is an ecoregion spanning North America and Canada, and is one of the WWF Global 200 ecoregions. Geography The Brooks–British Range tundra extends east and west along the Brooks Range which runs across northern Alaska and northeastern Yukon Territory. The Brooks Range is divided into western and eastern sections by the Anaktuvuk Pass. The Western Brooks Range is relatively low, while the Eastern Brooks Range is higher and more rugged, with larger areas of permanent ice and snow. The southern slopes of the Brooks Range are drained by the Yukon River, which empties westwards into the Bering Sea. The north slope drains northward into the Arctic Ocean. The British Range extends southwards from the eastern end of the Brooks Range, forming the divide between the Yukon and Mackenzie river basins and the boundary between the Yukon and Northwest territories. Protected areas 60.3% of the ecoregion is in protected areas. Protected areas include: Ivvavik National Park Vuntut National Park Gates of the Arctic National Park Arctic National Wildlife Refuge Gates of the Arctic Wilderness Noatak Wilderness Mollie Beattie Wilderness Central Arctic Management Area Wilderness Study Area Galbraith Lake Area of Critical Environmental Concern Poss Mountain Area of
