The Douglas Fir Douglas-fir, our most famous tree, thrives throughout the mountainous far west from Central British Columbia into Mexico and from the Pacific Ocean east as far as Colorado.
Close relatives live in California, Mexico, China, Taiwan, and Japan.
The trees can be very old and, on the coast, very large. Reliable statistics are not nearly so dramatic as those in folklore and fuzzy memories, but even careful figures indicate that Douglas-fir often live 750 years and the oldest may reach 1,300 years of age, with heights reaching 315 feet and trunk diameters as great as 14 feet.
