  • Species Scientific Name Hackelia cronquistii
  • Federal Listing Status Species of Concern

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.

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.
