Abstract: Analysis of growth, regeneration, and quality changes for white pine between the 1970's and 1980's in the six-state New England region. Growth rates seemed comparable among ail states except Rhode Island, where the percentage of growth (1.71%) seemed low. Over all states, the proportion of acreage in seedling/sapling white pine stands averaged too low (8%) to maintain the current volume and acreage of white pine. The diameter distribution of stems between 2 and 10 inches was J-shaped for all states combined, but deficiencies were noted in ail states except Massachusetts and Maine. Many of the small stems must occur in small openings or under partial canopies. 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.
