December 6, 2010, marks the fiftieth anniversary of the Arctic National Wildlife Refuge (ANWR). The refuge is the largest and northernmost national wildlife refuge in the United States. From north to south, ANWR spans 200 miles, and it covers 19.3 million acres—the size of South Carolina. Described as “the most biologically diverse conservation unit in the circumpolar north” by the U.S. Fish and Wildlife Service, ANWR is home to 42 species of fish, 37 species of land mammals, and eight species of marine mammals. The refuge is also full-time or part-time home to more than 200 bird species.
