This book was released on 1999 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: Three equations for predicting tree height as a function of diameter (outside bark) at breast height are presented for six species found in coastal regions of the Pacific Northwest. Foresters can use these "height-diameter" equations to avoid the time-consuming task of measuring heights of all individual trees in an inventory, a stand exam, or a timber cruise. Equation coefficients were estimated with weighted nonlinear regression techniques. Because the relationship between a tree's height and diameter depends on the tree's competitive position within the stand, alternative equations, including the average height and average diameter of the 40 largest-diameter trees/ac, are also presented. These equations are used in the Stand Management Cooperative version of ORGANON.

Download or read book Nonlinear Height-diameter Models for Nine Boreal Forest Tree Species in Ontario written by Ontario. Ministry of Natural Resources and published by Sault Ste. Marie : Ontario Ministry of Natural Resources. This book was released on 1999 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: The primary objectives of the work described in this report were to: develop nonlinear height-diameter models for nine boreal forest tree species in Ontario; evaluate the relative performance of these models calibrated for a range of site productivity & tree size; and select good model candidates for further validation & volume estimation in this region. In this work, 25 models were developed & fitted based on individual tree height & diameter data collected from permanent sample plots across northern Ontario. Available tree height & diameter data for each of the 9 species were split into two data sets: 90% of the data were used for model development and the rest were reserved for model validation. Comparison of mean square error values and mean coefficients of determination showed whether most sigmoidal & concave-downward equations capture the height-diameter relationships for Ontario tree species.

Download or read book Predicting Height for Undamaged and Damaged Trees in Southwest Oregon written by Mark L. Hanus and published by . This book was released on 1999 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Equations for predicting tree height as a function of diameter outside bark at breast height are presented for various tree species common to southwest Oregon. Data for damaged and undamaged trees were analyzed with weighted nonlinear regression techniques. The effects of specific damaging agents and their severity on the height-diameter relationship were explored. Damage correction multipliers were estimated, then used to correct predicted height where damage was noted. Because the relationship between height and diameter changes with the competitive position of the tree in a stand, alternative equations are presented that include the average height and diameter of the 40 largest-diameter undamaged conifer trees per acre. Foresters can use these "height-diameter" equations to reduce the time-consuming task of measuring heights of every tree in an inventory, stand exam, or timber cruise. They can also use these equations to estimate the change in height as diameter changes. These equations will be incorporated into the new southwest Oregon version of ORGANON, which extends the model to older stands and stands with a heavier component of hardwood species.

Download or read book The Ecology and Silviculture of Oaks, 3rd Edition written by Paul S Johnson and published by CABI. This book was released on 2019-04-10 with total page 645 pages. Available in PDF, EPUB and Kindle. Book excerpt: The third edition of The Ecology and Silviculture of Oaks is an updated and expanded edition that explores oak forests as responsive ecosystems. New chapters emphasize the importance of fire in sustaining and managing oak forests, the effects of a changing climate, and advanced artificial regeneration techniques. This new edition expands on silvicultural methods for restoring and sustaining oak woodlands and savannahs, and on management of ecosystem services, including wildlife habitat. It also incorporates new material on evaluating landscape-scale, and cumulative effects of management action compared with inaction. Nine of the fifteen chapters cover updated information on the geographic distribution of US oaks, oak regeneration dynamics, site productivity, stocking and stand development, even- and uneven-aged silvicultural methods, and growth and yield. This edition includes a new section with colour illustrations for improved visualization of complex relationships. This book is intended for forest and wildlife managers, ecologists, silviculturists, environmentalists, and students of those fields.
