Book Description
Strip clearcutting in the tolerant hardwood stands of the Great Lakes-St. Lawrence forest region of Ontario has resulted in excellent natural regeneration of yellow birch and sugar maple, but many of these stands are now overstocked. Research elsewhere has shown that thinning can increase diameter growth and thereby shorten rotation length. In 1986, a project was begun to evaluate the growth response of yellow birch and sugar maple saplings to thinning in a stand representative of conditions in the tolerant hardwood working group in Ontario. This report presents the five-year results of the crop tree release and compares them with those of similar thinning operations in eastern Canada and the United States. Recommendations are included.

Precommercial Crop-tree Thinning in a Mixed Northern Hardwood Stand
Author: Nancy G. Voorhis
Publisher:
ISBN:
Category : Forests and forestry
Languages : en
Pages : 8
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.
