Abstract:

SUMMARY: The U.S. Fish and Wildlife Service (Service) proposes to determine a plant Spiranthes diluvialis (Ute ladies’-tresses), to be a threatened species under the authority of the Endangered Species Act of 1973 (Act), as amended. Spiranthes diluvialis was historically found in riparian areas in Colorado, Utah, and Nevada. It is presently found in relatively undisturbed riparian areas in the greater Denver metropolitan area, Colorado (two populations), and in low elevation riparian areas in the Colorado River drainage in eastern Utah (five populations). The species’ small populations are threatened by habitat disturbance. In addition, S. diluvialis is potentially vulnerable to collecting for horticultural purposes. A determination that S. diluvialis is a threatened species would protect it under the authority of the Act. The Service seeks data and comments on this proposal. <br>

DATES: Comments from all interested parties must be received by January 14, 1991. Public hearing requests must be received by December 28, 1990. <br>
