Sinopsis
Excerpt from Comprehensive Tree Volume Equations for Major Species of New Mexico and Arizona, Vol. 1: Results and Methodology
Comprehensive tree volume equations and the methodology used to derive them are presented for the major tree species of New Mexico and Arizona. With these equations, the following gross and net volume types can be computed for both unforked and forked trees: total stem cubic foot volume; merchantable cubic foot volume to any top diameter between 3 and 8 inches, inside bark; International -inch board foot volume to a 6-inch top, inside bark; and Scribner board foot volume to a 6-inch top, inside bark. These equations were developed in such a manner as to eliminate many of the problems of consistency, compatibility, reliability, and flexibility associated with previous sets Of volume equations. This approach also allows the user to divide total stem cubic foot volume into top volume, merchantable volume, and stump volume. This last feature is useful for predicting the level of residues after harvesting to various top diameters.

Excerpt from Comprehensive Tree Volume Equations for Major Species of New Mexico and Arizona, Vol. 1: Results and Methodology
In addition to these, Meyer (1938) published gross volume tables for unforked ponderosa pine derived from data collected in several western States, including the Southwest. Volumes were given in three units of measure-tota1 stem cubic foot, Inter national -inch, and Scribner board foot.
More recently, the logarithmic method has been used to develop equations for unforked, gross Scribner board foot volume to an 8-inch top in white fir (peterson 1958) and in Englemann spruce (peterson and for unforked, gross cubic foot volume to both a 4 and an 8-inch top in immature and mature ponderosa pine (gaines and Peterson Minor (1961) used weighted, least squares regression to develop an equation for unforked, gross cubic foot volume to a 4-inch top in ponderosa pine, whereas Myers (1963) used ordinary, least squares regression with segmented data to develop unforked, gross volume equations for (a) total stem cubic foot volume, (b) merchantable cubic foot volume to a 4-inch and variable top limit, and (c) International -inch and Scribner board foot volumes to a variable top limit. (myers used the term variable top limitto indicate that the merchantable top diameter was a fixed function of a tree's diameter breast height and not to indicate that the top diameter was an independent variable in the volume equation. The latter type of equation can be converted to the former by defining the functional relationship between d.b.h. And top diameter.) The purpose of this study was to develop gross and net tree volume equations for forked and unforked trees of the major tree species found in Arizona and New Mexico. Species-national Forest (sp-nf) Specific equations were developed for the following units of measure-total stem cubic foot volume, merchantable cubic foot volume for any top diameter between 3 and 8 inches, and International l/4 - inch and Scribner board foot volumes to a -inch top. The resulting equations and methodology used to derive these equations are described in this paper. Volume tables for use in the field appear in a companion piece, Comprehensive tree volume equations for major species of New Mexico and Arizona: II. Tables for unforked trees.

Impresión bajo demandaLibrería: Forgotten Books, London, Reino Unido
Calificación del vendedor: 4 de 5 estrellas
Paperback. Condición: New. Print on Demand. This book presents detailed equations for calculating the volume of major tree species found in the American Southwest. These equations are organized into four main sections, corresponding to total stem volume, merchantable volume to any top diameter between three and eight inches, International 1/4-inch board foot volume to a six-inch top, and Scribner board foot volume to a six-inch top. Both unforked and forked trees are accounted for. The equations are derived from a comprehensive data set collected from five National Forests in Arizona and New Mexico. The author employs a consistent methodology to eliminate many of the reliability and flexibility issues associated with previous sets of volume equations. This approach allows users to divide total stem volume into top volume, merchantable volume, and stump volume. The book is a valuable resource for foresters involved in timber management planning, forest surveys, damage appraisal, and timber sale preparation. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item. Nº de ref. del artículo: 9781334172823_0
