Sterile milkvetch is endemic to the Owyhee Uplands. This species occurs along the Owyhee River, in bare gravelly and clay soils derived from weathered volcanic ash.
Limiting factors
Grazing by domestic livestock, mining, and weed invasion are among threats to this species.
Data gaps
Conduct seed collection focused on capturing potential genetic diversity. Develop propagation and transplanting protocols.
Conservation actions
Fence populations on public land to reduce impacts from off-road vehicles and grazing. Conduct long-term monitoring. Limit range improvement projects in sensitive areas.
