Davis' peppergrass occurs on hard, white clayey playas at elevations from 3100-5600 feet. These poorly-drained areas are often inundated with standing water.
Limiting factors
Off-road vehicles and trampling (due to use of habitat as watering sites for feral and domestic livestock) are among threats to this species.
Data gaps
Improve understanding of life history and reproductive biology. Analyze differences (observed morphological differences) between isolated populations. Develop propagation and transplanting protocols.
Conservation actions
Fence populations on public land to reduce impacts from off-road vehicles and grazing.
