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.
Stand tending treatments include the spacing of juvenile trees (pre-commercial thinning), commercial thinning of older trees, fertilizing, and pruning. This report notes the impact of stand tending on environmental values.
Provide information to forest practitioners considering commercial thinning and those that are currently planning and implementing commercial thinning programs in BC.
These guidelines are a correlation of many guidelines for uneven-aged stand management already in place in many forest districts and regions in British Columbia. The guidelines include a statement of principles, standards, and procedures and information on applicable stands; stratification; pre-harvest cruise and silviculture prescription; cutting permits; monetary assessments; pre-work guidance for harvesters; harvest monitoring; post-harvest assessments; stocking surveys; free growing surveys; and reporting.
