Special needs

Mulford's milkvetch is found in shrub-steppe and desert shrub communities in the semi-arid, cold-desert region of southeastern Oregon. This species occurs on moderately steep to steep southeast-, south-, and southwest-facing slopes, generally from 2200-2790 feet in elevation. Substrate may include sandy areas along rivers, old river deposits, sandy bluffs, and dune-like talus.

Limiting factors

Habitat loss due to urban development and habitat degradation have been linked to declines of Mulford's milkvetch. Fires leading to cheatgrass invasion, competition with invasive plants, herbicide drift from weed control efforts, livestock grazing and trampling, mining, off-road vehicle use, loss of pollinators due to insecticide spraying, and road development and maintenance are among the many threats to this species. Inbreeding depression is also a concern given population fragmentation and isolation.

Conservation actions

Monitor populations. Collect and store seeds from across the species' range. Conduct surveys to identify suitable protected habitat and establish new populations.
