Notice of Availability of a Final Recovery Plan for Six Mobile Basin Aquatic Snails

We, the Fish and Wildlife Service, announce the availability of the final recovery plan for six Mobile Basin aquatic snails. The six snails included in the recovery plan are: 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 (Basin) where they inhabit shoals, rapids and riffles of large streams and rivers above the Fall Line. All six species have disappeared from more than 90 percent of their historic ranges as a result of impoundment, channelization, mining, dredging, and pollution from point and non-point sources. The final recovery plan includes specific recovery objectives and criteria to be met in order to reclassify (downlist) the cylindrical lioplax, flat pebblesnail, and plicate rocksnail to threatened species and for the eventual delisting of all six species under the Endangered Species Act of 1973, as amended (Act).
