This book was released on 2001 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: This guidebook is intended to assist field practitioners in determining forest health issues and the incidence of forest health factors in high-hazard forest ecosystems. The first section describes the attributes of hazard & risk rating and briefly outlines some available hazard & risk rating systems. Section two covers forest development plan-level surveys, and includes procedures for landscape-level forest health factor surveys. Topics covered include aerial overview surveys, classification of damage, map processing, survey for pest incidence, and windthrow risk evaluation. The final section reviews stand-level surveys.

Download or read book Guidelines for Developing Stand Density Management Regimes written by British Columbia. Forest Practices Branch and published by British Columbia, Forest Practices Branch. This book was released on 1999 with total page 110 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stand density management is the process of controlling tree density within a stand to achieve desired objectives. Stand density management practices include the spacing of planted trees, pre-commercial thinning, and commercial thinning. A sound density management prescription must consider three elements of prediction: biological responses of the stand to treatment, economic implications of the treatment, and forest-level effects of the treatment. This document provides essential information on each of these elements, and provides a structured decision process for making site-specific density management prescriptions. Sections of the document cover the biological concepts of timber production, economic principles of timber production, forest planning considerations, the decision process, and density management planning tools. Includes glossary.

Available in PDF, EPUB and Kindle. Book excerpt: Sitka spruce, the largest of the world's spruces, is an important component of British Columbia's coastal forests. Its ecology gives it a special place in the sustainable management of the province's forests. However, in west coast forestry it is poorly known in comparison with its main coniferous companions -- Douglas-fir, western redcedar, and western hemlock. As an important international forestry resource, it is crucial that Sitka spruce -- its ecology and the ecosystems in which it occurs -- be clearly understood by those who are involved with its management.
