The Obama administration is setting aside 187,000 square miles in Alaska as a "critical habitat" for polar bears, an action that could restrict future offshore drilling for oil and gas. The total, which includes large areas of sea ice off the Alaska coast, is about 13,000 square miles, or 8.3 million acres, less than in a preliminary plan released last year.
Tom Strickland, assistant secretary for fish, wildlife and parks at the Interior Department, said the designation would help polar bears stave off extinction, recognizing that the greatest threat is the melting of Arctic sea ice caused by climate change.
"This critical habitat designation enables us to work with federal partners to ensure their actions within its boundaries do not harm polar bear populations," Strickland said. "We will continue to work toward comprehensive strategies for the long-term survival of this iconic species."
Designation of crucial habitat does not in itself block economic activity or other development, but requires federal officials to consider whether a proposed action would adversely affect the polar bear's habitat and interfere with its recovery.
Nearly 95% of the designated habitat is sea ice in the Beaufort and Chukchi seas off Alaska's northern coast. Polar bears spend most of their lives on frozen ocean where they hunt seals, breed and travel.
