This book was released on 2017-10-28 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Partial Cutting Practices for Old-Growth Lodgepole Pine From a silvicultural point of View, clearcutting is a sound and practical way of bringing mature and overmature lodgepole pine (pinus contorta Dougl.) forests under management, especially when timber production is a major objective. There are several reasons for clearcutting. Since these have been thoroughly discussed by Tackle they will only be highlighted here.

Book excerpt: Excerpt from Growth and Soil Moisture in Thinned Lodgepole Pine Excess trees cut to achieve the desired densities were mainly the diseased and small individuals. However, at the two lower densities, some excellent trees were cut to reach the desired level. At the two higher densities, not all diseased or low vigor trees could be eliminated. Spacing was also a factor in choosing trees to be cut. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Download or read book A Lodgepole Pine Commercial Thinning Trial in Kananaskis Alberta written by Stan Navratil and published by . This book was released on 2002 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1941, the Canadian Forestry Service established a commercial thinning trial in a stand dominated by 77-year-old lodgepole pine near Kananaskis, Alberta. Sample plots established in 1949 were re-measured in 1999, and this report presents the results of these measurements along with some earlier results. The results compare tree diameter growth & net periodic total volume increment between thinned plots and control (unthinned) plots. Management implications of the results are discussed.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Lodgepole Pine Logging Residues: Management Alternatives In recent years there has been a growing concern over timber harvesting practices and the disposal of the resulting logging residues. Although alternative methods of harvesting and handling residues have been suggested, there has often been a lack of information on the feasibility and on the effects these alternatives might have on the forest resource and its management, and on the environment, esthetics, and related matters. In 1971, a study was begun to evaluate a system of harvesting mature lodgepole pine (pinus contorta Dougl.) in which virtually all the logging residue - branches, tops, and dead and cull materia1-was yarded and chipped at the logging site. The study area is located in Wyoming near the Union Pass area of the Teton National Forest. U.s. Plywood Division of Champion International and the usda Forest Service1 cooperated in the study. Presently, chips produced in the study cannot be marketed locally. A critical part of evaluating the feasibility of field chipping, however, is to determine the costs and evaluate the methods for logging and chipping. In addition, the environmental and esthetic effects of logging that removes nearly all the woody material from the land are of interest. These concerns coupled with the opportunity to cooperate among the participants led to this study. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Book excerpt: Excerpt from Lodgepole Pine: A Lumber Species Not so long ago, lodgepole pine was, in the eyes of many, a weed tree with limited industrial use. However, during the last few years it has come into greater use for poles, pulp, and lumber. It is ap parent now that the species has considerable industrial potential, and that there is reason for optimism about its future. The purpose of this report is to appraise the suitability of lodgepole pine for lum ber-to consider its attributes and deficiencies for this purpose.

Download or read book Evaluation of Precommercial Thinning of Lodgepole Pine from Long term Research Installations in Alberta written by James Douglas Stewart and published by . This book was released on 2017 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: "As the forestry landbase shrinks and demand for wood increases, improving productivity of commercial forest stands becomes more important. Because of its commercial value and common occurrence, lodgepole pine is a candidate for productivity improvement. Regenerating lodgepole pine forests are often characterized by very high density and slow growth, limiting their value. Therefore, a variety of precommercial thinning treatments have been tried at long-term installations, which provide valuable data to evaluate projections from existing growth and yield models. In this report, we evaluate the stand growth and yield from different thinning treatments in long-term silviculture installations in the Upper Foothills (Gregg Burn and Teepee Pole Creek) and Lower Foothills (MacKay) subregions of Alberta. The MacKay installation was established in 1954 with the objective of determining whether precommercial thinning of lodgepole pine could improve merchantable volume and quality at a young age, and in turn shorten rotation and increase annual allowable cuts. The Gregg Burn and Teepee Pole Creek installations were established in the 1960s to assess the response of tree and stand growth to different juvenile spacing treatments, with densities ranging from 500 to 8 000 stems per hectare. Tree growth and survival in these installations are measured periodically to evaluate the effect of different intensities of thinning on the growth and yield of the lodgepole pine crop trees. To provide a decadal update to previous measurements and evaluation, published in 2006, we examined total and merchantable volumes in these installations using the most recent data (2011-2014). Our analysis found that thinning is unlikely to increase yields; however, if thinning is carried out for other reasons, judicious choice of a thinning regime can avoid a yield loss. Thinning to 2 000-3 000 stems per hectare appears to be optimal, maximizing the positive effect on tree growth without major losses in volume"--Abstract, p. iii.

Download or read book The Photoload Sampling Technique written by Robert E. Keane and published by . This book was released on 2007 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fire managers need better estimates of fuel loading so they can more accurately predict the potential fire behavior and effects of alternative fuel and ecosystem restoration treatments. This report presents a new fuel sampling method, called the photoload sampling technique, to quickly and accurately estimate loadings for six common surface fuel components (1 hr, 10 hr, 100 hr, and 1000 hr downed dead woody, shrub, and herbaceous fuels). This technique involves visually comparing fuel conditions in the field with photoload sequences to estimate fuel loadings. Photoload sequences are a series of downward-looking and close-up oblique photographs depicting a sequence of graduated fuel loadings of synthetic fuelbeds for each of the six fuel components. This report contains a set of photoload sequences that describe the range of fuel component loadings for common forest conditions in the northern Rocky Mountains of Montana, USA to estimate fuel loading in the field. A companion publication (RMRS-RP-61CD) details the methods used to create the photoload sequences and presents a comprehensive evaluation of the technique.

Download or read book Forest Mensuration written by Anthonie van Laar and published by Springer Science & Business Media. This book was released on 2007-07-20 with total page 390 pages. Available in PDF, EPUB and Kindle. Book excerpt: Van Laar and Akça’s popular text book, Forest Mensuration, was first published in 1997. Like that first edition, this modern update is based on extensive research, teaching and practical experience in both Europe, and the tropics and subtropics. However, it has also been extensively revised, and now includes chapters on remote sensing and the application of aerial photographs and satellite imagery. The book assumes no advanced knowledge of statistical methods, and combines practical techniques with important historical and disciplinary context. The result is a strong balance between a handbook and a valuable reference.
