In stands with significant mountain pine beetle (MPB) mortality, forest managers face a range of choices including clearcut harvesting, partial cutting, various rehabilitation strategies, and non-intervention. These choices involve many long-term costs, benefits, and risks, some of which can be assessed through economic analysis. After reviewing the context for this issue, the authors provided case studies that span the more likely stand-level problems faced by decision makers. All analyses were conducted from the perspective of the landowner (i.e., government) rather than the user of the resource (i.e., licensee). The insights from the case studies form a basis to answer the following core questions: Are some stand types better left unsalvaged? What economic/silvicultural assumptions produce higher stand values when salvaging is foregone? In areas that cannot be salvaged, is reforestation a profitable investment? Finally, does partial cutting make sense economically?--Document.

This guidebook has been prepared to help forest resource managers plan, prescribe, and implement sound forest practices that comply with the British Columbia Forest Practices Code. The information provided is to help users exercise professional judgment in developing site-specific management strategies and prescriptions to accommodate resource management objectives in the Cariboo Forest Region. The first section of the guidebook covers the legislative authority, background, definitions, and procedures for species selection, stocking (including maximum density for conifers), establishment, and free growing. It also includes a listing of the relevant sections of the Code. The second section includes criteria tables for regional forest establishment and information for determining free growing. The third section contains background and support information, forest health charts, and free growing damage standards.

Bigleaf maple (Acer macrophyllum Pursh) is a native broadleaf commonly found in the coastal forests of the Pacific Northwest. Following harvesting, vigorous sprouting from cut stumps can create large, rapidly growing clumps of maple sprouts, which can severely reduce the survival and growth of neighbouring conifers. A series of maple clump thinning treatments ranging from 0 to 400 clumps per hectare (cph) was assigned to the plots to study the effects of varying maple clump density on understorey light and conifer growth. This paper presents results of 14 years of post-treatment measurements from the Thomas and Comeau (1998) study, documenting understorey light levels, stand-level productivity, and individual tree, clump, and sprout growth. An assessment of the impact of maple thinning treatments is provided in an attempt to focus on the operational implications to forest productivity, temporal stand dynamics, and mixed species management.--Document.

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.

This guide presents site identification and interpretation information for forest ecosystems of the Vancouver Forest Region. Site identification is based on the biogeoclimatic ecosystem classification. The guide was prepared to assist users in describing and identifying forest sites and to provide management interpretations to assist users in preparing stand-level forest management prescriptions. The guide covers procedures for site assessment, a description of the biogeoclimatic units and the site units of the Vancouver Forest Region, management interpretations of tree species selection, slashburning, site productivity, competing vegetation potential, ground-based harvesting, pest risks of major conifer species, and wildlife diversity and habitat relationships. Appendices list indicator species; humus forms; keys to bedrock, hand-texturing soil, relative soil moisture regime, soil nutrient regime, and site sensitivity to slashburning; correlation of old and new biogeoclimatic and site units; and a site assessment form.

A stand management prescription is a document for describing actions to be carried out on a free-growing site to see that stand management activities are planned and implemented to maintain or enhance site productivity, to ensure that resource values are identified and taken into account, and to set out a series of stand management activities to produce a stand that meets the management objectives. This guide provides a logical sequence of steps on how to prepare and administer a stand management prescription in accordance with the Forest Practices Code of British Columbia. These steps include identification and collection of background information, setting of stand-level resource objectives, conducting fieldwork, preparation of the final prescription, production of the stand management prescription map, and administration.

Salvage logging—removing trees from a forested area in the wake of a catastrophic event such as a wildfire or hurricane—is highly controversial. Policymakers and those with an economic interest in harvesting trees typically argue that damaged areas should be logged so as to avoid “wasting” resources, while many forest ecologists contend that removing trees following a disturbance is harmful to a variety of forest species and can interfere with the natural process of ecosystem recovery. Salvage Logging and Its Ecological Consequences brings together three leading experts on forest ecology to explore a wide range of issues surrounding the practice of salvage logging. They gather and synthesize the latest research and information about its economic and ecological costs and benefits, and consider the impacts of salvage logging on ecosystem processes and biodiversity. The book examines • what salvage logging is and why it is controversial • natural and human disturbance regimes in forested ecosystems • differences between salvage harvesting and traditional timber harvesting • scientifically documented ecological impacts of salvage operations • the importance of land management objectives in determining appropriate post-disturbance interventions Brief case studies from around the world highlight a variety of projects, including operations that have followed wildfires, storms, volcanic eruptions, and insect infestations. In the final chapter, the authors discuss policy management implications and offer prescriptions for mitigating the impacts of future salvage harvesting efforts. Salvage Logging and Its Ecological Consequences is a “must-read” volume for policymakers, students, academics, practitioners, and professionals involved in all aspects of forest management, natural resource planning, and forest conservation.
