Abstract
The Fish and Wildlife Service (Service) determines the plant species Pediocactus winkleri (Winkler cactus), to be a threatened species. P. winkleri is endemic to lower elevations of the Colorado Plateau in south-central Utah. Four populations of P. winkleri are known. These populations total about 20,000 plants that grow on widely separated parcels of habitat between 1 (2.4 acres (ac)) and 20 (48 ac) hectares (ha) in size. This species is threatened by collection and by habitat disturbances due to mining, recreation, and livestock. This determination, that P. winkleri is a threatened species, implements protection under the Endangered Species Act of 1973, as amended.
