Cymopterus williamsii (Williams' springparsley) is a Bureau of Land Management (BLM) Sensitive Species, endemic to the southern Big Horn Mountains in north-central Wyoming. Surveys were conducted on BLM Worland Field Office administered lands in 2015 to address the lack of surveys on the west side of the Big Horn Mountains (in contrast with several surveys on the east side) and update species status information. The 2015 surveys resulted in the discovery of three new populations, slightly expanding the known range to the southwest, as well as providing more precise mapping of three populations previously located only to the square mile sections described on specimen labels. Data from the new surveys will be used to develop an updated potential distribution model and revise the current understanding of this rare species.
