Ecoregions

Northern Basin and Range

The Northern Basin and Range ecoregion covers the very large southeastern portion of the state, from Burns south to the Nevada border and from the Christmas Valley east to Idaho. It is largely a high elevation desert-like area dominated by sagebrush communities and habitats.

Special needs

Cronquist's stickseed occurs on sandy sagebrush slopes, and occasionally on moist slopes of ravines. This species is found at elevations between 2000-3640 feet.

Limiting factors

Cronquist's stickseed has limited distribution. Grazing, herbicide and insecticide use, agricultural development, invasive plant and crop seeding competition, and unregulated off-road vehicle and equestrian use threaten this species.

Data gaps

Evaluate the effects of light grazing on this species to determine its utility as a management tool. Develop propagation and transplanting protocols. Survey for additional populations.

Conservation actions

Continue to implement the Habitat Management Plan on public (Bureau of Land Management) land: manage recreational access, herbicide use, grazing, and insecticide use during flowering periods to maintain populations.
