Fish and Wildlife Service July 17, 2006 – Federal Register Recent Federal Regulation Documents

We, the U.S. Fish and Wildlife Service (Service), propose to designate areas of occupied, spring-related aquatic habitat in Texas as critical habitat for the Peck's cave amphipod (Stygobromus pecki), Comal Springs dryopid beetle (Stygoparnus comalensis), and Comal Springs riffle beetle (Heterelmis comalensis) under the Endangered Species Act of 1973, as amended (Act). The three listed species are known only from four spring systems in central Texas: Comal Springs and Hueco Springs in Comal County, and Fern Bank Springs and San Marcos Springs in Hays County. The total area proposed as critical habitat for the amphipod is about 38.5 ac (acres) (15.6 hectares (ha)), for the dryopid beetle is about 39.5 ac (16.0 ha), and for the riffle beetle is approximately 30.3 ac (12.3 ha).
