Endangered and Threatened Wildlife and Plants; Designation of Critical Habitat for Tumbling Creek Cavesnail

摘要

We, the U.S. Fish and Wildlife Service (Service), propose to designate critical habitat for the Tumbling Creek cavesnail (Antrobia culveri) under the Endangered Species Act of 1973, as amended (Act). We propose to designate as critical habitat approximately 25 acres (10.12 hectares) in one unit. The proposed critical habitat encompasses Tumbling Creek and associated springs, located near Protem, in Taney County, Missouri.
