Book excerpt: 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.

Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: Eastern white pine (Pinus strobus L.) is experiencing novel symptoms of dieback and mortality throughout its range in North America. Recent studies have found that two organisms, a fungal pathogen (Caliciopsis pinea Peck) and a scale insect (Matsucoccus macrocicatrices Richards), have emerged in association with a canker disease, which is driving the symptoms of this dieback phenomenon. Little is known about this insect-pathogen complex and its relationship to its host, including the colonization tendencies of the insect and pathogen, the nativity of the insect, and the genetic diversity and structure of the host in the Southern Appalachians region. I quantified the incidence of scale insects and pathogenic cankers within trees and among size classes and found that colonization of both the insect and the pathogen was consistent with the patterns of dieback and mortality of P. strobus, adding support to the hypothesis that these organisms are responsible for dieback symptoms and mortality. I also developed microsatellite markers to evaluate the present genetic diversity and structure of M. macrocicatrices populations within a biogeographical framework. I found that this insect is native to all regions in North America, and I posit it has likely been co-occurring with P. strobus, its obligate host, since the last glacial maximum. Therefore, recent introductions and invasional processes likely did not contribute to the recent emergence of M. macrocicatrices and its novel association with pathogens and dieback symptoms. Lastly, I elucidated the genetic diversity and population structure of P. strobus in the understudied Southern Appalachians and found that populations in this region are highly variable but not more so than those in more northern latitudes. Although this important tree species faces new threats, its high genetic variation suggests it may also have a substantial amount of adaptive potential. My results and interpretations herein provide comprehensive and important foundational knowledge about the organisms involved in the eastern white pine dieback phenomenon. This research has built a framework for future investigations into (1) the mechanism(s) that allows M. macrocicatrices to facilitate C. pinea infection, (2) the reason(s) why M. macrocicatrices has recently emerged as a pest, and (3) the appropriate management and conservation strategies for P. strobus persistence in its native range.
