资源简介:

This study involves the resampling of 40 0.2 acre plots throughout the two 35 year old white pine stands to determine the changes in stand structure over time (other survey dates include 1967, 1969, 1972, 1984, and 1989). Live and dead stems of each tree in a plot were measured (diameter at breast height, DBH). In addition, due to the recent infestations in both watersheds by the southern pine bark beetle, current status of trees was also noted.
