This document details a research project in British Columbia testing various silvicultural systems beyond traditional clearcutting to manage forests for multiple values, not just timber. The study evaluated the costs, productivity, tree damage, and soil disturbance associated with different harvesting methods used in the first phase of the project. The findings highlight the trade-offs between different approaches, noting that methods like clearcutting were most cost-effective for harvesting, while alternative systems resulted in varying levels of tree damage and soil disturbance.

This document serves as a comprehensive manual for commercial thinning within the province of British Columbia, detailing how to manage intermediate harvests where the wood removed covers extraction costs. The text outlines a multi-level strategy that integrates strategic planning at the landscape level with specific stand selection criteria, such as windfirmness, tree stability, and forest health. Its primary purpose is to offer practitioners a framework for using thinning as a strategic management tool to increase wood flow flexibility, enhance timber value, and protect non-timber resource values like biodiversity and visual landscapes. Furthermore, the guidelines establish strict administrative and legal requirements under the Forest Practices Code, mandating detailed silviculture prescriptions and rigorous post-harvest assessments to monitor soil disturbance and residual tree damage.

This document summarizes the early findings of a multidisciplinary study in Washington's Capitol Forest, which evaluates six different silvicultural regimes ranging from traditional clearcutting to group selection and untreated controls on an operational scale. By managing young-growth Douglas-fir stands for multiple objectives, researchers aim to provide forest managers with quantitative data on the biological, financial, and social consequences of various timber harvest patterns. Key themes include the comparative costs and feasibility of implementing these systems, the physical impact on soil and regeneration, and the public's aesthetic response to different landscape conditions. This study seeks to identify management options that can sustain high timber yields while simultaneously enhancing wildlife habitat and visual appeal to meet modern societal expectations.

This technical report details the outcomes of the Montane Alternative Silvicultural Systems study, which was prompted by operational concerns about forest regeneration and public pressure to limit clearcutting in high-elevation coastal regions of British Columbia. The core objective was to compare the operational productivity and financial viability of three alternative harvesting techniques including uniform shelterwood, green tree retention, and patch cutting against a conventional clearcut. The findings indicated that while these innovative systems could be applied successfully on gentle terrain, they resulted in significantly higher harvesting costs, with the shelterwood system proving to be 38% more expensive than clearcutting. The report also examined the acceptable low levels of site disturbance and soil compaction caused by the machinery, confirming that long-term success will rely on future monitoring of windthrow occurrence and regeneration success.

This report outlines the Montane Alternative Silvicultural Systems study, a large-scale project designed to test the ecological and operational feasibility of harvest methods beyond conventional clearcutting in coastal British Columbia montane forests. The research examined the biological and silvicultural impacts of four systems, including clearcut, patch cuts, green tree retention, and shelterwood, to address concerns regarding regeneration, aesthetics, and biodiversity in challenging high-elevation environments. Key findings indicated that while clearcutting was often the most cost-effective, alternative systems faced specific issues, such as increased operational costs and shade limitations that suppressed seedling growth in the shelterwood treatments. The results offer actionable implications, suggesting that small patch cuts and low retention levels can be successfully implemented without significantly reducing early plantation performance.

This paper provides an ecological and management overview of the old-growth forests in Canada's Montane Cordillera, a region spanning British Columbia and Alberta known for having the nation's most diverse range of old-growth coniferous forests due to its varied climates and natural disturbance regimes. The author emphasizes that a forest's history of climate and disturbance profoundly influences the abundance and structure of old-growth stands, noting that wetter climates support more abundant old forests and old-growth-dependent organisms, such as epiphytic lichens. The text critiques the challenges of defining old-growth, which is often arbitrary and dependent on an ecologist's viewpoint, and highlights the urgent need for a better ecological understanding to make informed land-use decisions for both the wet-belt rainforests and the drier forests, which are heavily impacted by human activities.

This technical report presents an analysis of a skyline partial cutting operation conducted in British Columbia's Interior Cedar-Hemlock zone. The primary goal was to evaluate the economic and operational feasibility of using a specific cable yarding system to meet modern silvicultural goals in this ecosystem. This report confirmed the importance of careful logging planning and developed productivity functions to help forest engineers predict and optimize the use of single- and multi-span skyline configurations in future partial cuts.

This document investigates harvesting small patch clearcuts in southeastern British Columbia. Faced with the challenge of balancing timber extraction with high recreational values and visually sensitive landscapes, this study aims to evaluate different harvesting systems. The study was conducted at Robson Ridge and Pilot Point and compared the productivity, costs, and site disturbance of ground-skidding and cable-yarding methods, highlighting key factors like terrain, machine type, and operational planning that influence the success of these silvicultural approaches in visually sensitive areas. The findings emphasize that meticulous planning, especially concerning road layouts and patch boundaries, is crucial for achieving both economic and environmental objectives in small patch clearcutting.

This document details the Revelstoke Community Forest Corporation's implementation of a single-tree selection silvicultural system in a second-growth forest area. The primary objectives of this alternative harvesting method were to maintain ungulate winter range, cultivate caribou habitat, minimize visual impacts from a nearby highway, and enhance future wood quality, particularly by reducing western white pine mortality. The document outlines the site's characteristics, the planning and prescription process for harvesting, and the challenges and successes of the logging operation, including cost analyses. This document concludes that while initial costs were higher, this approach offers a feasible way to access timber in sensitive areas that would otherwise be off-limits to traditional clearcutting, with an expectation of reduced costs as experience grows.
