Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Precommercial Crop-tree Thinning in a Mixed Northern Hardwood Stand written by Nancy G. Voorhis and published by . This book was released on 1990 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: S2Administrators of the Federal-State Cooperative Forest Management (CFM) program need sound investment guides for monitoring the efficiency of their program activities. This study, undertaken by the Northeastern Forest Experiment Station in cooperation with the Pennsylvania Department of Forests and Waters, provides CFM program administrators with a portion of the data they need to insure that their program and its adjunct, the Agricultural Conservation Program (ACP), are functioning in a manner that will produce maximum benefits for the dollars spent.S3.
