WebSep 22, 2024 · Port Orford cedar ( Chamaecyparis lawsoniana) is a long-lived conifer native to northwestern California and southwestern Oregon. It spans an elevational range from sea level to 5,000 feet or more. In forestry, the tree has both economic and ecological value (Zobel et al.1984).

It is shade tolerant, but not so much so as competing species western hemlock and white fir. The old-growth population near Coos Bay, Oregon, was wiped out by logging and wildfires in 1867–1868, and again by fire and root disease in 1936.
