Book Description
A dominant-tree thinning was conducted in 2003 in a 69-year-old even-aged northern hardwood stand, clearcut in about 1935, where a precommercial thinning study had been conducted in 1959. The 2003 commercial thinning concentrated on the removal of the early maturing, short-lived paper birch and aspen, the largest-diameter trees in the stand (hence the term "dominant-tree thinning"). Diameter growth rates after thinning, up to about 6 years per inch over the following 12 years, were acceptable although not greatly different from the unthinned plots. Basal area growth response was highly acceptable after thinning: about 2.3 ft2 per acre per year. Annual basal area growth was about negative 0.9 ft2 per acre on the unthinned plots. Understory development of beech and shrub species was dense under the thinned plots, and will require treatment/removal during the regeneration phase.
Precommercial Crop-tree Thinning in a Mixed Northern Hardwood Stand

Book Description
The effectiveness of precommercial crop tree thinning was investigated by thinning crop trees of paper birch, yellow birch, and sugar maple to two intensity levels at 8 years of age. Analysis of covariance on post thinning growth measurements taken 7 years later indicated a significant increase in diameter and crown-diameter growth, with the pattern of response varying by species. The study suggests that a uniform crop-tree thinning treatment for a stand composed of species with varying tolerances will rarely produce the best response for all the species.
