Abstract:

Surveys were conducted for two species designated Sensitive by the Bureau of Land Management in Wyoming: Antennaria arcuata (Meadow pussytoes) and Astragalus diversifolius (Meadow milkvetch). The project was originally proposed to fill survey gaps. The objective was greatly expanded to test potential distribution models. Both of the two species occupy alkaline meadows and had suspected survey coverage gaps in the BLM Lander Field Office. A third species, Cleome multicaulis (Many-stemmed spiderflower) is also known from alkaline meadows and was discovered in the study area for the first time during the course of surveys. In total, one new population of A. arcuata, two new populations of A. diversifolius and two new populations of C. multicaulis were documented by use of photointerpretation. Eighty-two negative survey points were produced and will be used to revise the three species’ potential distribution models. This report represents the most current and complete information on the three species as present in Wyoming, drawing from all earlier studies.
