Endangered and Threatened Wildlife and Plants; Listing the Plant Lepidium papilliferum (slickspot peppergrass) as Endangered

We, the U.S. Fish and Wildlife Service (Service), propose to list Lepidium papilliferum (slickspot peppergrass) as endangered pursuant to the Endangered Species Act of 1973, as amended (Act). Lepidium papilliferum is endemic to sagebrush-steppe habitat in southern Idaho. This species is threatened by a variety of immediate factors including: habitat destruction and fragmentation from agricultural and urban development; activities associated with, and grazing by, domestic livestock; competition from nonnative vegetation; alterations of the natural fire cycle; and fire rehabilitation activities. We solicit additional data and information that may assist us in making a final decision on this proposed action. We may revise this proposal to incorporate or address new information received during the comment period. This proposal, if made final, would extend the Federal protection and recovery provisions of the Act to this species.
