Growth and Yield-White pine is a long-lived tree commonly reaching 200 years if undisturbed; maximum age may exceed 450 years. It has a remarkable rate of growth compared to other pine and hardwood species within its range (20).eight growth of both planted and natural white pine is slow during the first 2 to 3 years. Afterwards, growth accelerates rapidly, peaking at an average annual rate of 1 m (3 ft) between 10 and 15 years on site index 80 (base 50 years) (6).
The bark of a white pine changes as it grows. When they are young they have smooth gray-green bark. As they mature their bark turns gray-brown and it becomes rough. Mature trees have broad scaly ridges 1 to 2 inches thick that run up and down the trees.
