Socorro and Alamosa Springsnail Recovery Plan (Alamosa Springsnail ('Trvoniaalamosae') and Socorro Springsnail ('Pyrqulopsis neomexicana') Recovery Plan)

摘要

The State of New Mexico listed the Alamosa and Socorro springsnails(springsnails) as endangered, group 2, on March 28, 1985 (Section 17-2-37 through 17-2-46 NMSA 1978). On October 30, 1991, the U.S. Fish and Wildlife Service also listed both species as endangered under the Endangered Species Act of 1973 (Act), as amended (Service 1991). Critical habitat for springsnails has not been proposed. The Service believes divulging the location of springs where springsnails are found would not be prudent; rather, such action could increase the risk of vandalism and further jeopardize the continued existence of both species. Constituent habitat elements important to continued survival of these species require a continued supply of free-flowing thermal spring water free of pollutants bordered by a zone of organic detritus and vegetation sufficient to support each species' biological and habitat requirements. The recovery priority for these species is 14, indicating they: (1) are taxonomically distinct; (2) face a low degree of threat; and (3) have high recovery potential.
