Photo 8/3/07, Perkins County, SD, Grand River National Grassland
This specimen was found in parabolic and blowout sand dunes in Northern Wheatgrass-Needlegrass Plains. These are apparently eolian sediments derived locally from weathered Ludlow Formation sandstone and/or sandbars deposted by the Grand River.
The species is rare across its range in the Northern Great Plains.
It is an early successional species, stabilizing active sand dunes such as dune slacks, blowouts, river banks, and disturbed sandy plains. It is vulnerable due to dune encroachment. Grazing animals maintain suitable habitat.
