Ecological Indicator Information

Shade-intolerant, submontane to subalpine, Western North American deciduous shrub distributed more in the Pacific than the Cordilleran region. Species occurs in maritime to submaritime cool mesothermal climates on very dry to moderately dry, nitrogen-medium soils; their occurrence decreases with increasing elevation, precipitation, and continentality. Sporadic to scattered in early-seral communities and open-canopy Douglas-fir forests on water-shedding sites. Characteristic of moisture­deficient sites.
