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).
Conifers are known for their longevity, with pines among the oldest trees on Earth. Ponderosa pines, common throughout the western United States, have a lifespan of 300 to 500 years, with an 800-year-old tree documented in Utah.
