Excerpt from Tree Form Quotients as Variables in Volume Estimation<br/><br/>Altherr (1960) and Assmann (1970) identify an approximate 4 Â percent underestimate of tree volume as calculated by Hohenadl's method. Five measurements failed to properly account for flare near the tree base. The underestimate can be corrected by using additional diameters measured at other proportions of tree height near the base of the tree. With nine diameters, tree volume can be estimated within 1 percent of volume estimates that use measurements every feet along the total tree stem (altherr The rationale of Hohenadl's method holds when additional proportional diameters are used to increase volume precision.

Tree Form Quotients as Variables in Volume Estimation (Classic Reprint)
Print-on-DemandAnbieter: Forgotten Books, London, Vereinigtes Königreich
Verkäuferbewertung 5 von 5 Sternen
Paperback. Zustand: New. Print on Demand. This book analyses Hohenadl's technique for defining tree volume and form quotients from diameters measured at fixed proportions of total tree height. The author modifies Hohenadl's procedure and applies it to two sets of data for western hemlock trees. The study defines volume differences in thinned stands and uses selected form quotients as variables to improve the accuracy and precision of standard tree volume equations. Estimating form quotients on standing trees requires less time than complete stem dendrometry, making the technique applicable to other tree species. The book's insights contribute to a deeper understanding of tree volume estimation and provide foresters and researchers with valuable practical tools. 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. Bestandsnummer des Verkäufers 9781390392661_0
