Endangered and Threatened Wildlife and Plants; Establishment of a Nonessential Experimental Population for Two Fishes (Boulder Darter and Spotfin Chub) in Shoal Creek, Tennessee and Alabama

摘要

We, the U.S. Fish and Wildlife Service (Service), in cooperation with the States of Tennessee and Alabama and with Conservation Fisheries, Inc., a nonprofit organization, propose to reintroduce one federally listed endangered fish, the boulder darter (Etheostoma wapiti), and one federally listed threatened fish, the spotfin chub (Cyprinella (=Hybopsis) monacha), into their historical habitat in Shoal Creek, Lauderdale County, Alabama, and Lawrence County, Tennessee. Based on the evaluation of species' experts, these species currently do not exist in this reach or its tributaries. These two fish are being reintroduced under section 10(j) of the Endangered Species Act of 1973, as amended (Act), and would be classified as a nonessential experimental population (NEP). The geographic boundaries of the proposed NEP would extend from the mouth of Long Branch, Lawrence County, Tennessee (Shoal Creek mile (CM) 41.7 (66.7 kilometers (km)), downstream to the backwaters of the Wilson Reservoir at Goose Shoals, Lauderdale County, Alabama (approximately CM 14 (22 km)), and would include the lower 5 CM (8 km) of all tributaries that enter this reach. These proposed reintroductions are recovery ac
