In 1959 a study of crop-tree release and species cleaning was established in a 25-year-old northern hardwood stand growing on an above-average hardwood site that resulted from a silvicultural clearcut in the White Mountains of New Hampshire. Three treatmentslight crop-tree release, heavy release, and species cleaningwere randomly assigned to quarter-acre plots, five plots per treatment, including five untreated plots. The stand was followed for 5 years and based on the results, treatment effects were projected to a stand age of 45 years. These projections were subjected to a financial analysis. The treatment plots were tallied at stand ages 56 (1990) and 69 (2003) years. We summarize the results of the early crop-tree release and species cleaning and provide a long-term financial perspective based on the new tallies. Our goal was to repeat the financial analysis and re-examine the results and conclusions of the original study. We found that the return on investment at stand ages 56 and 69 years was not as good as originally reported. The least expensive treatment, a light crop-tree release, gave the greatest return on investment. An opportunity for a commercial thinning between stand age 45 and 56 was missed and most likely would have improved the financial outcome of the treatments. Approximately 400 crop trees per acre were selected for release in 1959 but 200 crop trees per acre would have been more than sufficient and would have improved the financial outcome of the treatments by lowering initial cost. On a similarly good hardwood site, with an equally well stocked young stand, and good markets for small diameter roundwood, we only can speculate that releasing 200 or preferably fewer dominant or codominant trees per acre at stand age 25 followed by a commercial thinning when feasible after stand age 45 could be a good investment for a landowner.

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.

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.
