USFWS Announced Recovery Plans for Six Mobile River Basin Species

December 2, 2005

The U.S. Fish and Wildlife Service announced the availability of the final recovery plan for six Mobile Basin aquatic snails: the endangered cylindrical lioplax (Lioplax cyclostomaformis), flat pebblesnail (Lepyriam showalteri), and plicate rocksnail (Leptoxis ampla); and the threatened painted rocksnail (Leptoxis taeniata), round rocksnail (Leptoxis ampla), and lacy elimia (Elimia crenatella). All are endemic to the Mobile River Basin where they inhabit shoals, rapids and riffles of large streams and rivers above the Fall Line. All have disappeared from more than 90 percent of their historic ranges as a result of impoundment, channelization, mining, dredging, and pollution. The final recovery plan includes specific recovery objectives and criteria to be met in order to delist the species. 70 FR 72307
