BLM WY Desert Yellowhead Population Status Assessment

archived

A. Project Background Information: Desert yellowhead (Yermo xanthocephalus) is a perennial herb known from a single population in central Wyoming. This plant is listed as federally Threatened under the Endangered Species Act, and occurs exclusively on approximately 50 acres of BLM land. The BLM has been working closely with the U.S. Fish and Wildlife Service (FWS) to provide protection for this plant by incorporating conservation measures into its Resource Management Plans, limiting access to the area in order to minimize surface disturbing activity, and other similar mechanisms. By working with FWS in order to address known potential threats to this plant, progress is being made toward long-term recovery of this species. However, the current state of knowledge regarding population demographics, genetics, and long-term persistence of this plant is little understood. In its efforts to provide for the long-term population viability, BLM is funding a study to evaluate Desert yellowhead conservation status. B. Project Objective: The primary objective is to evaluate the long-term population stability and future viability of the Desert yellowhead. This information will be used by BLM as a basis for future management decisions on public lands occupied by this species, and will be used by FWS in their species recovery planning process. C. Statement of Joint Objectives/Project Management Plan: The applicant will conduct ecological research on the Desert yellowhead on Federal lands in Wyoming. Research will be conducted as part of the Great Plains Cooperative Ecosystems Studies Unit. BLM¿s role will primarily be one of project oversight and guidance to ensure key goals and objectives are achieved. BLM may be involved with some (relatively small por
