Moist to dry ravines, depressions, meadows, ridges, upland forests and occasionally on floodplains in the lowland and montane zones; common throughout BC, except infrequent on SW coast, absent on Queen Charlotte Islands; N to AK, YT and NT, E to NF and S to NY, NC, IN, AR, TX, NM, AZ, CA and MX.
A shade-intolerant, submontane to alpine, transcontinental North American, deciduous broad-leaved tree (rare in the Pacific region). Occurs in continental boreal and cool temperate climates on nitrogen-rich soils (Moder and Mull humus forms). Its occurrence increases with increasing continentality and latitude; sporadic in the coast-interior ecotone. Forms pure stands on base-rich, water-shedding and water-receiving sites following disturbance. A nurse species, it improves humus form quality through nutrient-rich litterfall. Regenerates abundantly from root suckers which quickly form a dense shrub layer and suppress the growth of shade-intolerant conifers. Characteristic of young-seral, continental forests.
