Ecoregions

Special needs

Big-flowered wooly meadowfoam is found in the Agate Desert region of Oregon. This species occurs along edges of vernal pools at elevations of approximately 1230-1300 feet. Habitat is characterized by shallow, Agate-Winlow soils and sparse vegetation, with few trees. Topography of the area is mound-swale, with an underlying impervious layer that traps winter rains.

Limiting factors

Destruction of vernal pool habitat, industrial and residential development, agricultural conversion, grazing, and competition with invasive plants have contributed to declines of big-flowered wooly meadowfoam.

Conservation actions

Continue population monitoring. Maintain current populations and restore vernal pool habitat at priority sites, including Denman Wildlife Management Area.
