RANGE OF BASALT CACTUS IN WASHINGTON
This map shows the locations of known and geolocated Basalt Cactus populations in Washington as of the early 2020s. The red dots do not show individual plants, but areas where several to many plants occur. The cactus occurs on mid-elevation anticlines, buttes, and hills such as the Frenchman Hills and Yakima Ridge, usually in areas of surface exposed basalt bedrock. The background colors correspond to regional ecological communities, the light blue being shrub-steppe. There are separate populations of Pediocactus nigripsinus in Idaho and Oregon.
