Endangered and Threatened Wildlife and Plants; Final Determination of Critical Habitat for the Alaska-Breeding Population of the Steller's Eider

We, the U.S. Fish and Wildlife Service (Service), designate critical habitat for the Alaska-breeding population of the Steller's eider (Polysticta stelleri), a threatened species listed pursuant to the Endangered Species Act of 1973, as amended (Act). Critical habitat for the Alaska-breeding population of the Steller's eider includes breeding habitat on the Yukon-Kuskokwim Delta (Y-K Delta) and 4 units in the marine waters of southwest Alaska, including the Kuskokwim Shoals in northern Kuskokwim Bay, and Seal Islands, Nelson Lagoon, and Izembek Lagoon on the north side of the Alaska Peninsula. These areas total approximately 7,333 square kilometers (approximately 2,830 square miles (mi<SUP>2</SUP>); 733,300 hectares; 1,811,984 acres) and 1,363 km (852 miles (mi)) of shoreline. Section 4 of the Act requires us to consider economic and other impacts of specifying any particular area as critical habitat. We solicited data and comments from the public on all aspects of the proposed rule and economic analysis. Section 7 of the Act prohibits destruction or adverse modification of critical habitat by any activity funded, authorized, or carried out by any Federal agency.
