Abstract: Astragalus rusbyi (Rusby’s milkvetch) grows primarily in ponderosa pine forests and in aspen groves, but it also may be found in mixed-conifer for-ests. Populations are mainly concentrated on basaltic soils in two areas in northern Arizona: around the San Francisco Peaks (primarily on the south-ern and western sides of the Peaks) and also in the vicinity of Kendrick Mountain. It is ranked “vulnerable” (G3) by NatureServe, a non-profit con-servation organization, and is on the U.S. Forest Service sensitive species list for Region 3 (Southwestern Region). Some of its habitat has been sub-jected to large wildfires over the last few decades. Other areas have under-gone ecological restoration treatments (tree thinning and prescribed burn-ing), and much of its range is slated to undergo such treatments in the near future. This fact sheet summarizes findings from previous research conduct-ed within its habitat and range.
