Ecological Indicator Information

A very shade-tolerant, submontane to subalpine, Western North American evergreen conifer distributed more in the Pacific than the Cordilleran region (absent on Queen Char­lotte Islands). Occurs in maritime to sub maritime sub-alpine boreal and summer-wet cool mesothermal climates on fresh to very moist soils; its occurrence increases with increasing elevation and precipi­tation, and decreases with increasing latitude and continentality. Grows in pure or mixed-species stands (usually with western or mountain hemlock) on water-shedding and water-receiving sites. Regenerates underneath closed­canopy stands, particularly on mycorrhizal Mors. (The mycorrhizae may explain this species' tolerance of nutrient-poor sites.) Most productive on submontane, fresh to moist, nutrient-rich (seepage) sites within wet cool mesothermal climates. Characteristic of wet maritime forests.
