Fish and Wildlife Service

Availability of the Recovery Plan for the Bruneau Hot Springsnail 
(Pyrgulopsis bruneauensis)

AGENCY: U.S. Fish and Wildlife Service, Interior.

ACTION: Notice of document availability.


SUMMARY: The U.S. Fish and Wildlife (Service) announces the 
availability of the final recovery plan for the Bruneau hot springsnail 
(Pyrgulopsis bruneauensis; springsnail). This endangered freshwater 
snail is a member of the family Hydrobiidae and occurs in a 5-mile 
reach of the Bruneau River and the lower one-third of Hot Creek in 
Owyhee County, Idaho.

ADDRESSES: Recovery plans that have been approved by the U.S. Fish and 
Wildlife Service are available on the World Wide Web at: http://www.r1.fws.gov/ecoservices/endangered/recovery/default.htm.
addition, recovery plans for the springsnail may also be obtained from: 
Fish and Wildlife Reference Service, 5430 Grosvenor Lane, Suite 110, 
Bethesda, Maryland 20814, 301-429-6403 or 800-582-3421. The fee for the 
plan varies.

FOR FURTHER INFORMATION CONTACT: Steven Lysne or Jeri Wood, U.S. Fish 
and Wildlife Service, Snake River Fish and Wildlife Office, 1387 S. 
Vinnell Way, Boise, Idaho 83709 (telephone; 208-378-5243).



    Recovery of endangered or threatened animals and plants is a 
primary goal of the Service's endangered species program. A species is 
considered recovered when the species' ecosystem is restored and/or 
threats to the species are removed so that self-sustaining and self-
regulating populations of the species can be supported as persistent 
members of native biotic communities. Recovery plans describe actions 
considered necessary for the conservation of the species, establish 
criteria for downlisting or delisting listed species, and estimate the 
time and cost associated with implementing the measures needed for 
    The Endangered Species Act (Act) (16 U.S.C. 1531 et seq.), requires 
the development of recovery plans for listed species unless such a plan 
would not promote the conservation of a particular species. Section 
4(f) of the Act requires that during recovery plan development, the 
Service provide public notice and an opportunity for public review and 
comment. Information presented during the public comment period has 
been considered in the preparation of this final recovery plan, and is 
summarized in an appendix to the recovery plan. The Service will 
forward substantive comments regarding recovery plan implementation to 
appropriate Federal or other entities so that they can take these 
comments into account during the course of implementing recovery 
    The springsnail was listed as endangered on June 17, 1998 (FR 63 
32981). This freshwater, aquatic snail exists only in an approximately 
5-mile reach of the Bruneau River and its tributary, Hot Creek, in 
southwestern Idaho. The springsnail inhabits flowing geothermal springs 
and seeps with temperatures ranging from 15.7 to 36.9 degrees Celsius. 
The springsnail is found in these habitats on the exposed surfaces of 
various substrates including rocks, gravel, sand, mud, and algal films. 
The principal threat to the springsnail is the reduction and/or 
elimination of their geothermal spring habitat as a result of 
agricultural groundwater withdrawals.
    The objective of this plan is to provide a framework for the 
recovery of the springsnail so that protection by the Act is no longer 
necessary. Recovery is contingent upon protecting and managing the 
remaining springsnail habitat to maintain and enhance viable 
populations of the springsnail.
    The springsnail will be considered for reclassification when: (1) 
Water levels in the regional geothermal aquifer have increased and 
stabilized at 815 meters (2,674 feet) in elevation; (2) the total 
number of geothermal springs discharging within the recovery area is 
200 or more and are distributed within the current range of the 
springsnail; (3) more than two-thirds of available geothermal springs 
within the recovery area are occupied by stable, medium to high density 
populations of reproducing hot springsnails; and (4) groundwater levels 
are permanently protected against further reductions through 
implementation of groundwater management activities.


    The authority for this action is section 4(f) of the Endangered 
Species Act, 16 U.S.C. 1533 (f).
