Wildlife Impacts from Oil Drilling in the Refuge
The Arctic National Wildlife Refuge, the largest wildlife refuge in the United States, encompasses 19 million acres and provides habitat to a diverse array of wildlife including millions of migratory birds, caribou, three species of bears (polar, grizzly and black bears), wolves, Dall sheep, muskoxen, arctic and red foxes, wolverines, plus many more. The nearby continental shelf provides the coastal waters with a rich nutrient base, which in turn supports a variety of marine mammals including the endangered bowhead whale.
The Arctic Refuge contains one of the most fragile and ecologically sensitive ecosystems in the world. It represents the only protected area in the world that includes an intact arctic, subarctic, and boreal ecosystem, thus retaining the natural dynamics that have existed for thousands of years. The Arctic environment is extremely vulnerable to long-lasting disturbance because the harsh climate and obviously short growing seasons allow species that have been harmed little time to recover.
The proposed oil and gas development would occur on the 1.5-million acre coastal plain found along the Beaufort Sea. This area is the most sensitive in the entire refuge and habitat loss that occurs here will impact the entire Arctic Refuge. The coastal plain habitat within the Arctic Refuge is also unique from other regions of the North Slope of Alaska because it is relatively narrow (only 15-40 miles across), limiting the alternatives for animals using these areas.
