Acer macrophyllum is naturally found in western North America from Alaska to southern California primarily within 300 km (186 Miles) from the coast from sea level to an altitude of 2,135 m (7,000ft) growing in hardwood or conifer forests or in pure stands. 

It prefers an open sunny position and it grows in most well-drained moderately fertile moist soils and is frost and drought tolerant but it prefers a cool moist environment. 

The Bigleaf Maple is grown for its spreading habit and timber. It is planted in parks and large gardens as a specimen or shade tree and used in woodland settings. It establishes in 3-4 years and is long-lived and grows on the coast and in the mountains. It is also harvested commercially and used for making furniture and piano frames or is used as fuel-wood.
