ENV: Mobile Basin Snails

Six Mobile Bay Basin snails were recently pushed to protected status. Mike Quinn sends along a note saying the recovery plans are available.
RECOVERY PLAN FOR 6 MOBILE RIVER BASIN SPECIES - 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
