Interior Department, Fish and Wildlife Service
We, the U.S. Fish and Wildlife Service (Service), propose threatened status pursuant to the Endangered Species Act of 1973, as amended (Act), for the Chiricahua leopard frog (Rana chiricahuensis). The Chiricahua leopard frog is now absent from many historical localities and numerous mountain ranges, valleys, and drainages within its former range. In areas where it is still present, populations are often few, small, and widely scattered. Known threats include habitat alteration, destruction, and fragmentation, predation by nonnative organisms, and disease. Habitat loss results from water diversions, dredging, livestock grazing, mining, degraded water quality, and groundwater pumping. Problems associated with small population numbers and size also threaten the species. Evidence suggests that adverse effects from water-borne contaminants may also threaten this species. This proposed rule, if made final, would implement Federal protection to this species and provide funding for development and implementation of recovery actions.

SUMMARY: We, the U.S. Fish and Wildlife Service (Service), propose threatened status pursuant to the Endangered Species Act of 1973, as amended (Act), for the Chiricahua leopard frog ( Rana chiricahuensis ). The Chiricahua leopard frog is now absent from many historical localities and numerous mountain ranges, valleys, and drainages within its former range. In areas where it is still present, populations are often few, small, and widely scattered. Known threats include habitat alteration, destruction, and fragmentation, predation by nonnative organisms, and disease. Habitat loss results from water diversions, dredging, livestock grazing, mining, degraded water quality, and groundwater pumping. Problems associated with small population numbers and size also threaten the species. Evidence suggests that adverse effects from water-borne contaminants may also threaten this species. This proposed rule, if made final, would implement Federal protection to this species and provide funding for development and implementation of recovery actions. DATES: We must receive comments from all interested parties by September 12, 2000. We must receive public hearing requests by July 31, 2000. ADDRESSES: Send comments and materials to the Field Supervisor, Arizona Ecological Services Field Office, U.S. Fish and Wildlife Service, 2321 West Royal Pal…
