SUMMARY: The Fish and Wildlife Service (Service) determines Coryphantha scheeri var, robustispina (Pima pineapple cactus) to be an endangered species under the authority of the Endangered Species Act of 1973 (Act), as amended. The Service proposed the species for listing as endangered on April 20, 1992. This species is known from Pima and Santa Cruz Counties, southern Arizona, and northern Sonora, Mexico. Threats to the species include illegal collection, habitat degradation due to recreation, historical and present overuse of the habitat by livestock, and habitat loss due to mining, agriculture, road construction, urbanization, and range management practices to increase livestock forage. This action will implement Federal protection provided by the Act for Pima pineapple cactus. Critical habitat is not being designated.
