# Alaska Maritime National Wildlife Refuge

The Alaska Maritime National Wildlife Refuge (often shortened to Alaska Maritime or AMNWR) is a United States National Wildlife Refuge comprising 2,400 islands, headlands, rocks, islets, spires and reefs in Alaska, with a total area of 4.9 million acres (20,000 km$^2$), of which 2.64 million acres (10,700 km$^2$) is wilderness. The refuge stretches from Cape Lisburne on the Chukchi Sea to the tip of the Aleutian Islands in the west and Forrester Island in the southern Alaska Panhandle region in the east. The refuge has diverse landforms and terrains, including tundra, rainforest, cliffs, volcanoes, beaches, lakes, and streams.
Alaska Maritime National Wildlife Refuge is well known for its abundance of seabirds. About 75 percent of Alaskan native marine birds, 15 to 30 million among 55 species, use the refuge. AMNWR also provides a nesting habitat for an estimated 40 million seabirds, representing 80 percent of all seabirds in North America. The birds congregate in "bird cities" (colonies) along the coast. Each species has a specialized nesting site (rock ledge, crevice, boulder rubble, pinnacle, or burrow). Other animals present in this refuge include caribou, sea lions, bears, coyotes, seals, Canada lynx, beavers, foxes, muskrats, wolf packs, moose, walrus, river otters, marten, whales, Dall sheep and sea otters.
The administrative headquarters and visitor center are located in Homer, Alaska. In 1968, Simeonof National Wildlife Refuge, part of the Alaska Maritime National Wildlife Refuge, was designated as a National Natural Landmark by the National Park Service.
