Endangered and Threatened Wildlife and Plants; Proposal to List the San Xavier Talussnail as Endangered

摘要

The U.S. Fish and Wildlife Service (Service) proposes to list the San Xavier talussnail (Sonorella eremita) as an endangered species under the Endangered Species Act of 1973, as amended (Act). The San Xavier talussnail is found only in an area of 15 by 30 meters (m) (50 by 100 feet (ft)) on private land in Pima County, Arizona. The primary threat to the species results from its vulnerability to habitat disturbances that would remove talus, increase interstitial soil, or alter moisture accumulation and retention. This proposal, if made final, would implement Federal protection provided by the Act for the San Xavier talussnail. The Service seeks data and comments from the public on this proposal.
