Book excerpt: Excerpt from Large-Crowned Planted Ponderosa Pine Respond Well to Thinning Thinning study results provide a portion of the information on which timber stand improvement policy is formulated. To be useful these studies should sample a wide range of sites, tree sizes, age classes, and geo graphic locations in planted and natural stands. The study reported here is one of a number of thinning experiments established in various stands through out the Pacific Northwest during the period from 1957 to 1965. This report summarizes initial 11 - year results after thinning a 33 - year - old ponderosa pine plantation. 1.

Book excerpt: Excerpt from Thinning Ponderosa Pine in the Southwest The true value of a shortened rotation has not been appreciated heretofore. The fact that total cubic - volume growth seldom increases during the first years following thinning has led to the erroneous conclusion that thinning doesn't pay. The potential long - term gain has been discounted or overlooked entirely. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

This book was released on 2017-11-19 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Crop-Tree Thinning of Ponderosa Pine in the Pacific Northwest Mowat has reported on several earlier crop-tree thinning studies made in the Pacific Northwest. Thinning treatments varied from ramov ing only trees with interlacing crowns to cutting all trees whose crowns were within 3 feet of the crop tree. Differences between growth of released and unreleased trees were small. Heavily released trees grew at the rate of only about 1 inch per decade compared to inch for selected crop trees in the unthinned stand. Furthermore, these early experiments did not show any clear-cut effect of overstory on understory tree growth and vice versa. The studies reported here go a step further as some crop trees were released to a point that approached area thinning. In addition, the interrelationships of overstory and understory tree growth were examined. Results are important to land managers who have trees already released by the crop - tree method and to managers who intend to embark on an extensive thinning program in ponderosa pine.

Download or read book Growth of Planted Ponderosa Pine Thinned to Different Stocking Levels in Northern California written by William W. Oliver and published by . This book was released on 1979 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Growth was strongly related to growing stock level (GSL) for 5 years after thinning 20-year-old poles on Site Index50 115 land at the Elliot Ranch Plantation in northern California. Five GSL's- basal areas anticipated when trees average 10 inches d. b. h. or more - ranging from 40 to 160 square feet per acre were tested. Periodic annual increment (PAI) in diameter decreased curvilinearly from 0.51 to 0.21 inch, with increasing GSL's from 40 to 160. But only trees in plots heavily thinned to GSL 40 (and briefly in GSL 70) grew faster in diameter after thinning than these same trees grew before thinning. PAI in basal area and net volume rose steadily with increasing GSL9s, reaching 9.0 square feet and 255 cubic feet per acre, respectively, at GSL 160. Apparently, even light thinning reduced volume production, but thinning still is recommended to shorten time until first commercial entry and to promote stand health.

Available in PDF, EPUB and Kindle. Book excerpt: Growth of the most widely distributed pine in North America is under joint study by the western Forest and Range Experiment Stations of the U.S. Forest Service. Young, even-aged ponderosa pine (Pinus ponderosa Laws.) stands are being examined over a wide range of tree sizes, stand densities, and site index. The single plan that co-ordinates activities of the four Stations is an example of how the growing stock problem can be handled for a widely distributed species. The wide range in treatments should provide data needed to answer the questions that arise in evaluation and application of multiple use management of ponderosa pine forests.

This book was released on 2018-09-07 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Ponderosa Pine Saplings Respond to Control of Spacing and Understory Vegetation Recent forest inventories indicate that about 5 million acres of commercial pon derosa pine forest land east of the Cascade Range in Washington and Oregon have a dense understory of suppressed trees.l On many additional acres, the overstory has been re moved, leaving dense thickets of 40 to 80-year-old, sapling-sized trees. Some man agers have chosen to thin these residual stands while others, still hesitant about the invest ment in thinning, have elected to let the understory develop naturally. Most agree, however, that if these stands are to make reasonable progress toward producing a merchantable product, they must be thinned. The type of precommercial thinning selected for these stands may imply the product mix of a multiple use manager or the anticipated market of a private com pany. If a forester chooses a narrow spacing, he is forecasting a market for small trees by the time the next thinning is needed. On the other hand, choice of a wide spacing implies that the forester is aiming toward larger trees suitable for sawing or peeling or that he is interested in increasing forage and/or water yields. Both routes may be equally productive. Since optimum tree spacing depends on product objective, the forester must know the growth possibilities at a number of spacings to satisfy varied management objectives. In addition, he needs to know the competitive effects of understory vegetation, soil moisture availability, and limb development, all of which can affect the production of useful wood.
