This document is a part of a long-running Levels-of-Growing-Stock (LOGS) Cooperative Study in Douglas-fir stands, specifically detailing findings from installations at Sayward Forest and Shawnigan Lake in British Columbia. The core objective of the LOGS study is to understand how different thinning intensities impact cumulative wood production, individual tree size, and growth ratios in young Douglas-fir stands. This progress report summarizes data from these two Canadian sites, showing that volume growth is strongly tied to the amount of growing stock retained, and that thinning significantly influences tree size distribution and live crown development, suggesting potential for future productivity gains. The study also offers comparisons between various thinning regimes and unthhinned control plots, revealing the long-term implications of silvicultural practices on forest stands.

This document introduces a method for prioritizing commercial thinning in forests by integrating high-density drone laser scanning (DLS) data with tree-ring measurements. This research uses DLS to quantify individual tree growth and competition, specifically identifying that crown volume is the strongest predictor of recent basal area growth. This innovative approach allows for the creation of detailed spatial maps, including a new "growth competition index," which can guide forest managers in optimizing thinning strategies across large areas, moving beyond traditional stand-level assessments to a more precise, intra-stand management. The study emphasizes how this technology provides timely, fine-scale information to enhance the efficiency and effectiveness of silvicultural practices, particularly commercial thinning.

This document investigates the economic viability of commercial thinning in second-growth forests on British Columbia's coast. Using the TIPSY 4.2 modeling software, the author simulates various scenarios by inputting existing forest data and economic variables to predict stand yields and financial outcomes. While acknowledging the environmental and silvicultural benefits of commercial thinning (like improving stand quality, accelerating wood volume, and enhancing biodiversity) the study's initial findings suggest that, under current conditions, commercial thinning is not economically feasible. However, it also explores the potential for future use, considering factors such as different thinning intensities, harvesting methods, and the impact of government assistance programs.

This paper explores strategies to mitigate timber supply shortages in British Columbia (BC), a problem exacerbated by climate change and past natural disturbances like the mountain pine beetle outbreak. The authors investigate two primary forest management approaches: commercial thinning and diverse plantings, including assisted species migration. By simulating the long-term effects of these interventions in a case study area, the study concludes that combining commercial thinning with species diversification offers the most promising solution to sustain future timber supply in BC, emphasizing the importance of adaptive forest management in the face of environmental challenges.

This document investigates the long-term effects of thinning on a 53-year-old lodgepole pine stand. The core purpose is to understand how different thinning intensities impact tree growth, stand health, and resistance to pests over nearly five decades. A key finding suggests that heavy thinning may help "beetle-proof" stands against the destructive mountain pine beetle, contributing to greater net volume increments despite initial mortality from other factors like snow. While acknowledging some study limitations due to initial variability, the report provides valuable insights into sustainable forest management practices for older lodgepole pine.

This document is a detailed inventory of numerous forestry research projects across British Columbia. It systematically catalogues various long-term studies examining different silvicultural systems, which are methods for managing forest growth and harvesting timber. The document is structured geographically, listing trials in the Southern Interior, Northern Interior, and Coast regions, as well as smaller, province-wide trials, university research forests, demonstration areas, and operational case studies. For each listed project, the document typically provides information such as the establishment year, location, ecological zone, tested silvicultural systems (like clearcutting, shelterwood, and group selection), trial objectives (e.g., impacts on regeneration, wildlife, or disease), and often a list of associated publications and contact information, highlighting the extensive research network in the province.

This case study details a research project investigating alternative silvicultural systems to clearcutting in the steep-sloped old-growth forests of the Queen Charlotte Islands (now Haida Gwaii). The study, initiated in 1992, compared the effects of single-tree selection, two levels of group selection, and clearcutting on regeneration (both natural and planted) and residual stand characteristics over a seven-year period. Key findings address the effectiveness of these methods in promoting the regeneration of western hemlock, Sitka spruce, and western redcedar, as well as the impact on residual tree damage and browsing pressure from Sitka black-tailed deer, ultimately aiming to inform sustainable forest management practices in this sensitive ecosystem.

This report details a research project in the dry Douglas-fir forests of central British Columbia, initiated in 2001 at Farwell Canyon. The study investigated the effects of partial cutting on forest stand dynamics, specifically examining how different harvesting methods, coupled with pre-commercial thinning and prescribed burning, could achieve objectives like improved wildlife forage, enhanced residual tree growth, and increased fire resilience. The report presents data collected over 10-14 years following these treatments, analyzing changes in stand structure, tree growth, and regeneration patterns to assess the long-term outcomes of these forest management techniques in this specific ecosystem.

This paper examines the costs and productivity of different timber harvesting methods in the interior wet-belt of British Columbia, specifically focusing on maintaining habitat for mountain caribou. The study compares group selection harvesting, where small patches of forest are removed, with clearcutting and single-tree selection. Its primary purpose is to document the economic implications of a harvesting approach designed to balance timber extraction with the ecological needs of caribou in old-growth cedar-hemlock forests.

This paper explores the effects of partial cutting, a forest management technique aimed at creating stands similar to natural uneven-aged forests, on wildlife trees and coarse woody debris in the wet forests of interior British Columbia. The authors introduce a new classification system based on functional habitat features ("Types") of these dead and dying wood components that are crucial for various wildlife species. By presenting preliminary data from a long-term study, the paper investigates how different partial cutting methods, specifically single tree selection and group selection, influence the occurrence of these vital habitat structures, ultimately seeking to inform forest management practices for biodiversity conservation.
