Tree of the Week - Eastern White Pine


Now that we've covered the most valuable mast producing trees that populate northeastern forests; we're going to spend some time focusing on some of the more prevalent conifers. Of course, eastern white pine is one of the most valuable, generating around $120 per MBF currently. Eastern white pine is a valuable cover species in northeastern forests; where it can be found in masses. Of the northeastern conifers; eastern white pine is the most preferable timber species, as it is a highly-demanded, fast-growing species, capable of growing in excess of 18" per year in favorable conditions.

While white pine buds are a favorite browse food of whitetail deer; the trees are more important for their cover during the winter months. White pine, along with most other conifers, are very important in reducing the snow load on the ground, which is key to the movement and ultimately, survival, of wildlife. Lesser snow loads means that wildlife burns less calories in search of food; which is very important when nutritious food sources are hard to come by. It is important to note that of the native conifer species, white pine has some of the weakest branches; meaning it is not as good at reducing the snow load as other species. However, considering its value as a timber species; it makes for a great species in a dual-management setting; as most other conifers are substantially slower growing and are less valuable.

Managing white pine is no different than the valuable mast species; they should be tightly planted to ensure proper stem form. The species tolerates moderately wet, well-draining soil better than other pine species; but does not tolerate dry or swampy conditions well. White Pine grows best on higher terrain; ie. hillsides, ridges, etc., and can tolerate up to 60% shade when young; making it a great successional planting. Avoiding low areas where cool, moist air collects can help prevent white pine blister rust.

In regards to the management of these species for wildlife; it is important to manage them in a way that provides natural winter travel corridors between food sources and bedding areas. Further; these travel corridors would be best composed primarily of conifer species; as it will do the best job of reducing the snow load to a managable level.

Overall, eastern white pine is a great all-around tree species; as a high-value, fast growing timber species capable of producing great cover habitat for wildlife.
