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 forests. Populations are mainly concentrated on basaltic soils in two areas in northern Arizona: around the San Francisco Peaks (primarily on the southern and western sides of the Peaks) and also in the vicinity of Kendrick Mountain. It is ranked 'vulnerable' (G3) by NatureServe, a non-profit conservation organization, and is on the U.S. Forest Service sensitive species list for Region 3 (Southwestern Region). Some of its habitat has been subjected to large wildfires over the last few decades. Other areas have under-gone ecological restoration treatments (tree thinning and prescribed burning), 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.
