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.

Book excerpt: 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.

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 comprehensive guide to effective hardwood forest management Extending 235,000 square miles from New York to Georgia and fromVirginia to Missouri, the Central Hardwoods Region harbors the mostextensive concentration of deciduous hardwoods in the world. Asharvests in the Pacific Northwest decline and timber prices rise,the maturing stands of mixed species in this central U.S. regionare a rich and valuable resource that is increasingly vulnerable toexploitation. This timely book examines all of the key ecological,social, and economic management considerations essential to utilizeand sustain these vital woodlands effectively. First, it develops the background necessary to understand whatmakes the hardwood eco-system function, with a thorough examinationof the physiography, geology, soils, and climate of the region anda historical overview of its evolution and development frompre-European settlement to the present. Then, species by species,the book details the silvical characteristics of 34 important treespecies. Next, it offers expert recommendations for effectiveforest treatment and management, from specific concerns such astimber production, pollution, and financial planning to broaderissues, including the role of the natural resource manager and thebiological potential of the entire region. Generously supplemented with graphs and photos, Ecology andManagement of Central Hardwood Forests is important reading forforesters, natural resource managers, regional planners,environmental scientists, governmental officials--everyone with astake in the future of this critical living resource.

Available in PDF, EPUB and Kindle. Book excerpt: S2Small-sawtimber white oak crop trees in Kentucky were released by a crown-touching technique. In two cutting treatments, 20 and 34 crop trees were released per acre at a total cost of $35 and $42, respectively. Both treatments yielded commercial volumes of cut material. Total mean merchantable volume (>5.0 inches d.b.h.) in cut trees was 693 cubic feet/acre, with approximately 2,400 board feet/acre in sawtimber (2 11.0 inches d.b.h.). On the basis of early crop-tree stem response, the released trees are growing 0.16 inch/year compared with 0.13 inch/year for the unreleased trees. S3.
