Abstract:

SUMMARY: The U.S. Fish and Wildlife Service (Service) determines the plant Spiranthes diluvialis (Ute ladies’- tresses) to be a threatened Species under the authority of the Endangered Species Act of 1973 (Act), as amended. S. 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): in wetlands near Utah Lake in northern Utah (two populations); and in low elevation riparian areas in the Colorado River drainage in eastern Utah (six populations). This species is threatened primarily by habitat loss and modification, though its small populations and low reproductive rate make it vulnerable to other threats also. This determination that S. diluvialis is a threatened species protects it under the authority of the Act. <br>

EFFECTIVE DATE: February 18,1992.
