Book Description
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 Description
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.

Book Description
Excerpt from Predicting Growth of Eastern White Pine Data for this study came from the New Hampshire plots of the Hatch 149 project entitled Effects of Site and Stocking on the Growth of Eastern White Pine, a cooperative study made jointly by the Universities of Maine, Massachusetts, and New Hampshire, and the Northeastern Forest Experiment Sta tion of the Forest Service (usda). The Soil Conservation Ser vice (usda) classified the soils on each plot. The authors wish to acknowledge the work of Peter H. Allen in establishing the plots, Charles Breeding in classifying the soils on each plot, Robert Joly in analyzing the soil-site data, and William B. Leak in suggesting some data analyses. Computations were run on the ibm system at the University of New Hampshire. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
