![]() The net benefit of pruning reached its maximum 30 years after pruning and stayed positive for 101 years, suggesting that early pruning is a viable practice for reserved pines. Unpruned pines, on average, peaked in net present value 52 years post-release. Pinus strobus, commonly called the eastern white pine, northern white pine, white pine, Weymouth pine (British), and soft pine is a large pine native to. Retaining isolated white pine trees at final harvest of other conifers in the Acadian forest enhances growth response and can be financially lucrative, especially if forest managers reserve younger pines (under 12 inches diameter) with vigorous crowns. The White pine is a 5-needle pine tree Very soft appearance of the needle pads Due to low annual growth. White Pine is commonly transplanted today as a landscape evergreen tree and is also sold as a cut Christmas tree. ![]() They assessed financial performance of released pines in unpruned and hypothetical pruned scenarios. The Japanese white pine is a hardy outdoor bonsai. Researchers used computer modeling to forecast future tree growth and computerized sawmill simulation to estimate post-release standing tree values. In the 18th and 19th centuries these massive trees were used for building. They collected measurements on all trees from the ground and climbed 9 trees to obtain branch measurements. Eastern White Pine trees grows very fast, resulting in tall and long lived trees. NSRC researchers examined growth response of 77 isolated, released pines and determined their financial maturity at 8 sites throughout Maine’s Acadian spruce-fir region. Many spruce budworm era (1975-90) salvage harvests in the Northern Forest retained immature white pine reserve trees. In old field monocultures, value depends on early manual pruning, but in mixed-species stands, competition from shade tolerant conifers (spruce, fire, hemlock) can accelerate branch shedding and minimize weevil attack, creating high quality logs without manual pruning. Growth Rate This tree grows at a fast rate, with height increases of more than 24' per year. Most woods grown pines are not of high value because of poor natural branch shedding and white pine weevil deformation. About the white pine tree Identification: White pines can be identified by their clusters of long, soft, blue-green needles that grow in bundles of five. The eastern white pine grows to a height of 5080 and a spread of 2040 at maturity. In colonial times, these tall trees were used to make masts for the British Royal Navy ships.Eastern white pine is potentially a high-value species because of large market premiums for clear lumber, so financial return for harvesting white pine depends on forest management designed to develop high quality basal logs. If it grows somewhere that it’s exposed to a lot of wind, the eastern white pine can become a bit lopsided, with small, short branches on the side that faces the wind. Show your provincial pride and plant an eastern white pine – it’s the provincial tree of Ontario! If you plant it in direct sun, it will grow quickly and is ideal for blocking an unsightly view or for creating shade for your house. ![]() Soil: Grows in any soil type prefers sand or sandy loam Pine tree: Type of Plant: Evergreen, coniferous tree: Origin: Northern Hemisphere, parts of the tropics and temperate regions of the Southern Hemisphere.Shade: Tolerates partial shade when younger A 2ft tall potted White Pine tree can be over 12 ft tall in 5 years, in good soil, with adequate moisture and total weed and grass control. Eastern white pine is a large tree with a pyramidal crown when young, becoming flattened.Moisture: Tolerates different moisture levels.Size: 20 to 35 metres tall, trunk 60 to 140 centimetres in diameter.It grows quickly and best with full sunlight. Where it is foundįound in most of Ontario, the eastern white pine can grow to be more than 40 metres tall. Its bark is dark greyish brown with broad thick ridges that are 2 to five centimetres thick. Good seed crops aren’t produced until trees are 20 or 30 years old, and then only every 3 to 5 years. It is a truly magnificent tree attaining a height of 80 feet or more at maturity with a diameter of two to three feet. Growth and Yield- White pine is a long-lived tree commonly reaching 200 years if undisturbed maximum age may exceed 450 years. The eastern white pine’s cones are 8 to 20 cm long and they hang down from the branches. Its leaves or needles occur in bundles or fascicles of five, 3-5 inches long, bluish green, with fine white lines or stomata. It’s easy to recognize the eastern white pine because its needles grow in bunches of five. It has skinny needles that are 6 to 12 centimetres long.
