Survey for Astragalus oniciformis during June 1994 in the Great Rift lava flow, Craters of the Moon National Monument and Preserve, Idaho - species range expansion via new populations found east of the flow.
Popovich SJ. Survey for Astragalus oniciformis during June 1994 in the Great Rift lava flow, Craters of the Moon National Monument and Preserve, Idaho - species range expansion via new populations found east of the flow.
This report presents results of an ambitious survey effort conducted during June 1994 by Steve Popovich to survey for, document additional sites of, and to better delineate the range of the locally-endemic plant Astragalus oniciformis. Several sites occur in areas administered by the BLM within CRMO. The survey resulted in finding significant new disjunct populations east of the Great Rift lava flows and confident circumscription of the species range. Associated species are also listed. Other rare plants noted include Gymnosteris parvula and Stipa webberi.
