This report describes the results of a reconnaissance-level field study to determine the occurrence of natural white pine regeneration on three areas in northwestern Ontario. The areas included Devon Township in a 90-year-old mixedwood stand containing white pine, red pine, and trembling aspen; Sibley Peninsula in a 140-year-old white pine stand 33 years after an experimental harvesting trial; and Greenwood Lake under a fully stocked 200-year-old white pine stand, in adjacent 10-year-old clearcuts planted or seeded to jack pine, and under a partially cut, naturally regenerating white pine stand 10 years after cutting.

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.
