Abstract:

Ute ladies' tresses (Spiranthes diluvialis) is a rare orchid occurring in riparian zones of the Intermountain and Rocky Mountain west. It was listed as Threatened under the Endangered Species Act in 1992. Known populations in Idaho occur along the Snake River between the Henry's Fork confluence and Palisades Dam, a stretch of 49 river miles. The U.S. Fish and Wildlife Service has established a Section 7 consultation area that includes wetland and riparian habitats below 7,000 feet in Idaho. <br>

This report summarizes the 1998 inventory for Ute ladies' tresses on the Targhee National Forest and Caribou National Forest lands administered by the Targhee. Numerous valleys within the South Fork of the Snake and Henry's Fork of the Snake watersheds were surveyed, as well as a number of watersheds on the Dubois Ranger District. No new populations of Ute ladies' tresses were found in 1998, and in most cases suitable habitat was limited or nonexistent. This report includes an ecological description of each site, and an assessment of potentially suitable habitat. The precise locations of all the stream segments surveyed are marked on the Targhee travel plan map, filed with this report. The preliminary status survey report for Ute ladies' tresses (Moseley 1997) and the updated status survey should be used to supplement this report (and vice versa), and to provide the overall context for Ute ladies' tresses and its potential habitat in Idaho. <br>
