WASHINGTON (CN) – The Three Forks springsnail is endangered and the San Bernardino springsnail is threatened under the Endangered Species Act, according to a U.S. Fish and Wildlife Service listing decision.
The USFWS also designates critical habitat for both species, under the act. Approximately 17 acres are designated as critical habitat for the Three Forks springsnail in Apache County, Arizona, and approximately 2 acres for the San Bernardino springsnail in Cochise County, Arizona
Historically, the Three Forks springsnail populated many springs and waters in Apache County, Arizona, but in recent years their range has been reduced to two springs.
The Three Forks springsnail is subject to predation by nonnative crayfish, fire retardant chemicals, the spread of other nonnative species, and drought.
The San Bernardino springsnail was recently discovered to inhabit at least nine springs in Mexico and so is not thought to be endangered at this time although habitat is likely to be threatened throughout its entire range in both the United States and Mexico due to potential springhead inundation, and water depletion and diversion.
