Endangered and Threatened Wildlife and Plants; Designation of Critical Habitat for Lost River Sucker and Shortnose Sucker

Краткое содержание

We, the U.S. Fish and Wildlife Service (Service), propose to designate critical habitat for the Lost River sucker (Deltistes luxatus) and shortnose sucker (Chasmistes brevirostris) under the Endangered Species Act of 1973, as amended (Act). In total, we are proposing as critical habitat approximately 146 miles (234 kilometers) of streams and 117,848 acres (47,691 hectares) of lakes and reservoirs for Lost River sucker and approximately 128 miles (207 kilometers) of streams and 123,590 acres (50,015 hectares) of lakes and reservoirs for shortnose sucker. The proposed critical habitat is located in Klamath and Lake Counties, Oregon, and Modoc County, California. On December 1, 1994, we published proposed critical habitat for Lost River sucker and shortnose sucker. This new proposed rule uses updated information concerning Lost River sucker's and shortnose sucker's ecology, as well as the technological advancements made available since preparing the 1994 proposed rule, to inform our proposed critical habitat designation for Lost River sucker and shortnose sucker.
