S2Precommercial thinning was done in a 12-year-old Appalachian hardwood sapling stand in West Virginia. Two crop-tree release techniques were used-crown touching and crown touching plus 5 feet. Results indicated that both treatments significantly increased & year d.b.h. growth for released yellow-poplar and black cherry crop trees. Although there was a major increase in d.b.h. growth, caution is suggested when using the crown-touching plus 5 feet treatment as butt-log quality response was not conclusive. Releasing crop trees with the crown-touching approach seems appropriate in sapling stands when applied to desirable stems on better sites. S3.

S2A crown-touching release of 12-year-old black cherry and yellow-poplar crop trees on a good site required removing an average of 14 trees for every crop tree. An average of 80 crop trees per acre was left free-to-grow with an average growing space of 4.7 feet on all sides of the crown. Basal spraying cost $0.80 per crop tree, stem injecting cost $0.61 per crop tree, and chain saw felling cost $0.42 per crop tree. Cost indicators for each release method and suggestions for cost savings are provided.S3.

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.
