Longevity.—Little is known concerning the longevity of this pine, whichappears to grow rapidly in diameter for the first 40 or 50 years. Trees from 66 FOREST TREES OF THE PACIFIC SLOPE. 12 to 14 inches in diameter are from 75 to 80 years old. It is probably a short-lived tree, rarely exceeding 150 or 200 years.
