Scope note:

Species of North American fir tree having several forms, one with reflexed bracts, that are sometimes considered to be separate species. Trees may reach heights in excess of 90 m (295 feet) and have diameters of more than 4 m (13 feet), but most contemporary stands are composed of trees that are much smaller, due to the fact that many old specimens have been logged. It is noted as one of the best timber trees in North America, as well as a popular ornamental and Christmas tree, and is used for reforestation along the Pacific Coast.
