Special needs

Lawrence's milkvetch is found on deep loess soils in Palouse grasslands.

Limiting factors

This narrowly-distributed species' is endemic to the Columbia Plateau, including western Umatilla and Morrow Counties. Habitat loss, namely agricultural conversion, has impacted Lawrence's milkvetch. Grazing, herbicide use, road construction, and invasive plants (primarily knapweeds) are additional risk factors.
