Abstract:

The Bruneau hot springsnail (Pyrgulopsis bruneauensis) was listed as endangered on June 17, 1998 (FR 63 32981). The species currently survives in approximately 89, out of 155, small, flowing geothermal springs and seeps along an approximately 6.9-km (4.3-mi) reach of the Bruneau River and its tributary Hot Creek in southwestern Idaho. The species is found in a narrow elevation range of 803.7 to 815.7 m (2,636.9 to 2,676.1 ft). The Bruneau hot springsnail has been found in flowing geothermal springs and seeps with temperatures ranging from 15.7 to 36.9 degrees C (60.3 to 98.4 degrees F), with the highest densities of springsnails noted at temperatures ranging from 22.8 to 36.6 degrees C (73 to 98 degrees F). The principal threat to this species is the reduction and/or elimination of their geothermal spring habitat as a result of agricultural-related groundwater withdrawal and pumping. The objective of this draft recovery plan is to recover the species to the point where delisting is warranted.
