Abstract:

Lepidium papilliferum (slickspot peppergrass) is an annual or biennial forb endemic to southwestern Idaho that has seen much of its original sagebrush-steppe habitat destroyed or seriously degraded over the past century. The documented downward conservation trend of this species resulted in it being made a Candidate species for listing under the Endangered Species Act in 1999. In 2000, the Bureau of Land Management and Conservation Data Center entered into a Challenge Cost-share agreement to conduct a field investigation for Lepidium papilliferum in the Mountain Home to Glenns Ferry corridor, an area known to have unsurveyed potential habitat for this species. We visited over 20 areas and searched approximately 5,000 acres. Three new occurrences, and additions to one previously known occurrence were discovered during the field investigation. The occurrences contained a total of fewer than 3,000 Lepidium papilliferum plants and covered under five acres.
