Presentation summary:
Among their most critical decisions, foresters must judge the age arrangement in a stand, and then decide what silviculture to apply. Basing those choices on the diameter distribution alone may lead to treatments that do not sustain the values of interest or capitalize on the productive capacity of a site. In fact, research clearly tells us not to believe the old adage that even-age stands have bell-shaped diameter distributions, Instead, mid-aged and older even-aged northern hardwoods generally have a distribution that looks more reverse-J in shape. Among these stands, taking out the larger/older trees and leaving the smaller/older ones will result in unexpected responses due to major difference in the diameter growth patterns between trees in even- vs. uneven-aged stands. That of the small trees in uneven-aged stands generally increases follo
