Ecological Indicator Information

A shade-tolerant to shade-intolerant, submontane to montane, Western North American evergreen conifer distributed less in the Pacific than the Cordilleran region. Occurs in cool temperate and cool mesothermal climates; its occurrence decreases with increasing latitude, precipitation, and elevation. Grows in mixed-species stands (usually with DouglasĀ­fir or western redcedar) on water-shedding and water-receiving sites. Tolerates fluctuating groundwater tables. Most productive on submontane, fresh to moist, nutrient-rich (alluvial and seepage) sites. Characteristic of nutrient-rich sites.
