Confidence in Rank High or Medium or Low Freeman reports that most of the populations he observed in the Cimarron NG were in “unstable, disturbance dependent habitats, such as blowouts, river banks, and sand or gravel bars” and that populations may have suffered some decline through habitat degradation, in particular from damage by off- 5 road vehicles or livestock grazing [rank A].

Criteria Rank Rationale Literature Citations Species is found on sand dunes, in sandy shortgrass- and sandsage prairies, and sand- or gravel banks along rivers or intermittent streams (fide Barneby and Freeman). Freeman noted that species shows a preference for disturbance-dependent habitats; consequently, individual populations may naturally have a rather short lifespan. Where he observed species in the Cimarron NG, Freeman reported that populations were found in areas of heavy use by off-road vehicles and that the habitat was frequently degraded and 6 plants mechanically damaged. Freeman added that livestock grazing may also adversely affect species • Barneby 1977 • Freeman 1989 Habitat Trend A (through trampling of habitat and encouraging bank or dune erosion). Freeman recommended restricting in R2 access to areas where species is known to occur in the Cimarron NG. Ostlie et al. report that conversion of • Osltie et al. 1997 shortgrass prairie to croplands, and fire suppression and livestock grazing of sandsage prairies, have resulted in changes in the abundance and species composition to both of these communities. It is likely that both management techniques have resulted in loss of habitat for species throughout R2. Confidence in Rank High or Medium or Low Species is found on sand dunes, in sandy shortgrass and sandsage prairies, and sand- or gravel banks along rivers or intermittent streams (fide Barneby and Freeman). Populations may decline under 7 management practices that promote of dune stabilization. As noted in sect 6, habitat may be vulnerable to a Habitat variety of human land use practices, such as off-road vehicles and livestock grazing. Freeman notes that, • Barneby 1977 Vulnerability A where it occurs along water courses, species may also be vulnerable to changes in hydrology from human • Freeman 1989 or water use.

National Forests in the Rocky Mountain Region where species is KNOWN (K) or LIKELY (L)1 to occur:

1 Likely is defined as more likely to occur than not occur on the National Forest or Grassland. This generally can be thought of as having a 50% chance or greater of appearing on NFS lands.
