Arctic coastal tundra (WWF

Source of bioregions data: Olson, D. M. and E. Dinerstein. The Global 200: Priority ecoregions for global conservation. (PDF file) Annals of the Missouri Botanical Garden 89:125-126.
Distinctiveness (1=highest,4=lowest): 1
This ecoregion supports a wide variety of wildlife and is an important breeding and calving ground for many species. In particular, major caribou herds migrate here to calve and many species of birds breed here.*
Conservation Status (1=most endangered, 5=most
intact): 4 (relatively stable)
Over 90% of habitat remains intact. The main threat is associated with oil development at Prudhoe Bay and possible future development in the coastal plain of the Arctic National Wildlife Refuge. Roads and pipelines may disrupt migration patterns.*
