Abstract:

One important concern in the conversion of even-aged stands to an uneven-aged condition through individual-tree or small-group cutting is the growth response throughout the diameter-class distribution, especially of the understory trees. Increment-core sampling of an older, uneven-aged northern hardwood stand in New Hampshire under management for about 50 years established the baseline diameter-growth responses of the sapling, pole, and sawtimber strata. Growth responses of the poletimber and sawtimber in a 70-year-old even-aged stand were comparable to the uneven-aged stand after an initial partial cutting treatment; growth of the understory began approaching comparable rates after the second entry about 25 years after the first cut.
