Ecological Indicator Information

A shade-tolerant/intolerant, montane to subalpine, West­ern North American deciduous shrub distributed more in the Cordilleran than the Pacific region. Occurs predominantly in continental subalpine boreal and cool temperate climates on nitrogen-medium soils; its occurrence increases with increasing elevation and continentality. Sporadic to scattered in herbaceous understories on water-shedding and water-receiving sites in the coast-interior ecotone. Characteristic of subalpine continental forests.
