Évaluation du vendeur 5 sur 5 étoiles
Paperback. Etat : New. Print on Demand. This book explores how a forest of Douglas fir, Western hemlock, and Western redcedar trees develops over 25 years when planted at varying distances apart on an excellent site in British Columbia. The author's research over this period found early decisions regarding tree spacing had a significant impact on the final size and value of the grown timber. Tree height was less affected than average tree diameter, which varied significantly with spacing. Stem form, crown width, and crown shape are all examined as influenced by tree density. These factors, along with crown development, also influenced tree mortality from factors including snow damage. Analysis of basal area, total and merchantable volume per hectare suggests that initial wide spacing is recommended to maximize the value of the timber produced on this type of site. The results are particularly significant to forest managers interested in growing trees to meet a variety of objectives. The book's research enhances our understanding of how stand development is influenced by different levels of density. 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. N° de réf. du vendeur 9781390439670_0
