Refuge
The island is part of the Bering Sea unit of the Alaska Maritime National Wildlife Refuge and is designated Bering Sea Wilderness. Its habitat supports over 5 million nesting seabirds.[1]
Reindeer
In 1944 the U.S. Coast Guard introduced 29 reindeer as an emergency food source. The herd grew to about 6,000 by 1963 and then fell to 42 animals within two years. A study linked the crash to limited food and the severe 1963–1964 winter, and the reindeer were gone by the 1980s.[1]
History
A Russian-American Company group led by Demid Kulikalov made the first recorded settlement attempt in 1809. The Coast Guard operated a LORAN transmitter station there in the 1940s.[1]
