Distribution Overview
Noble fir is native (in the U.S.) to the Cascade Mountains and high peaks of the Coast Range (3,000 to 5,000 feet) from western Washington through western Oregon to northwest California. It is usually found growing with other conifers in high mountain regions where short, cool growing seasons are common. It prefers moist soils and deep winter snows.
