Abstract

This study resulted from an agreement between Nebraska Game and Parks Commission (NGPC) and the United States Fish and Wildlife Service (USFW). After the 1996 discovery of Spiranthes diluvialis, in western Nebraska, NGPC was seeking to determine the extent of the Nebraska population. Information on the wet meadow community of orchid occurrence in Nebraska and eastern Wyoming was needed. This report includes descriptions of communities inventoried, Spiranthes diluvialis populations, and additional species monitored by Nebraska and Wyoming Natural Heritage programs.

Between May and September 1997, potential Spiranthes diluvialis habitat was inventoried for occurrences of the orchid. For all sites surveyed, site summary survey forms and maps were completed. At sites where natural communities or species monitored by the Nebraska and Wyoming Natural Heritage programs were identified, element occurrence records (EOR) with maps were completed. For all Nebraska sites, Natural Resource Conservation Service (i.e. Soil Conservation Service) soil surveys were examined. Soil maps with taxa delineated were prepared for each survey site. When soil samples were collected, soil analysis results are listed. Data are presented alphabetically by survey sites.
