## Abstract

We, the U.S. Fish and Wildlife Service (Service), determine that Lepidium papilliferum (slickspot peppergrass), a plant species from southwest Idaho, is a threatened species under the Endangered Species Act of 1973, as amended (Act). This final rule implements the Federal protections provided by the Act for this species. We have determined that critical habitat for L. papilliferum is prudent but not determinable at this time.
