S2The Universities of Maine, Massachusetts, and New Hampshire, in cooperation with the Northeastern Forest Experiment Station, initiated in 1959-60 a study of the effects of site and stocking on the growth of eastern white pine. The primary purposes of the study were to develop equations for: (1) predicting the volume increment per acre of pure, even-aged, white pine stands from observable characteristics of the stand, soil, and topography; and (2) predicting the increment of individual white pine trees related to characteristics of the tree, stand, and site. By 1965, measurements of stand growth and development for a 3-year period were available from nearly all field plots. A preliminary analysis revealed that one or more additional remeasurements should be taken before a final summary of the periodic growth of trees and stands is made. Nevertheless, useful and accurate relationships were developed between stand yield, or volumes per acre, and stand age, site, and stocking; and this information is presented in this paper. Yield tables based on the plot data from New Hampshire, using stand height in place of age and site index, have been published by Barrett and Allen (1966).S3.

America was built on white pine. From the 1600s through the Civil War and beyond, it was used to build the nation’s ships and houses, barns, and bridges. It became a symbol of independence, adorning the Americans’ flag at Bunker Hill, and an economic engine, generating three times more wealth than the California gold rush. Yet this popularity came at a cost: by the end of the 19th century, clear cutting had decimated much of America’s white pine forests. In White Pine: The Natural and Human History of a Foundational American Tree, ecologist and writer John Pastor takes readers on walk through history, connecting the white pine forests that remain today to a legacy of destruction and renewal. Since the clear-cutting era, naturalists, foresters, and scientists have taken up the quest to restore the great white pine forests. White Pine follows this centuries-long endeavor, illuminating how the efforts shaped Americans’ understanding of key scientific ideas, from forest succession to the importance of fire. With his keen naturalist’s eye, Pastor shows us why restoring the vitality of these forests has not been simple: a host of other creatures depend on white pine and white pine depends on them. In weaving together cultural and natural history, White Pine celebrates the way humans are connected to the forest—and to the larger natural world. Today, white pine forests have begun to recover, but face the growing threat of climate change. White Pine shows us that hope for healthy forests lies in understanding the lessons of history, so that iconic species survive as a touchstone for future generations.

The growth, regeneration, and quality of white pine between the 1970's and 1980's were analyzed for the six-state New England region. Growth was comparable among all states except for Rhode Island where the growth (1.71%) was low in comparison with other states and with the growth of red maple (4.29%) within the state. For all states, the proportion of acreage in white pine seedling/sapling stands was too small (8%) to maintain the current volume and acreage of the species. However, stems in the 2- to 10-inch diameter class were adequately J-shaped over all states to sustain the species. Because many of these small stems must be in small openings or under partial canopies, efforts to regenerate and release white pine seem warranted. The percentage of volume in grades 1 and 2 more than doubled between the 1970's and 1980's in all states except Massachusetts and Connecticut where the percentage remained about constant.
