Greenup delay refers to the time it takes for a newly harvested forest stand to reach a specified average height, signaling successful regeneration. The report evaluates how enhanced silviculture techniques, such as site preparation, planting, brushing, and the use of genetically improved stock, can reduce this delay and increase the short-term and long-term timber supply to optimize tree growth and forest yield. -

The core purpose was to monitor and compare vegetation changes in areas that experienced no burn, moderate burns, or severe burns following a fall slashburn. The research highlights the dominant plant species that emerged in each environment over four years, noting differences in species composition and competition dynamics, particularly concerning the impact of a fall slashburn and soil seepage on vegetation development. -
A Retrospective Investigation of Partial Cuts in the ICHmw1 and ICHmk1 in the Golden Forest District

The primary purpose of the study was to explore the relationship between regeneration density and various site factors following partial harvesting. Researchers found that while abundant natural regeneration occurred, its success was not strongly correlated with specific harvest treatments, but rather more significantly influenced by factors like brush potential and site preparation. The report recommends guidelines for residual basal area levels to optimize seed supply and moisture protection in these forest ecosystems. -

Recognizing the historical influence of First Nations' cultural burning and the current challenges of overstocked stands and wildfire risk, it outlines a strategic shift in silvicultural practices. The report details Best Management Practices (BMPs), structured around key aspects like appropriate silvicultural systems, restoration thinning, regeneration, and resilience to disturbances like fire and pests. The document aims to guide practitioners and inform policy, moving towards healthier, more resilient Douglas-fir ecosystems that balance ecological values, community safety, and sustainable resource use. -
Silviculture Practices for Enhancing Old Forest Stand Structure in Red- and Blue-Listed Plant Communities in the CDFmm Interim Document
This document addresses the challenge of balancing timber harvesting with the conservation of at-risk plant communities that depend on mature and old forest conditions in British Columbia's Coastal Douglas Fir biogeoclimatic zone. Recognizing the sca...This document addresses the challenge of balancing timber harvesting with the conservation of at-risk plant communities that depend on mature and old forest conditions in British Columbia's Coastal Douglas Fir biogeoclimatic zone. Recognizing the scarcity of these older forests, the document outlines silvicultural practices aimed at maintaining existing structural diversity in high-conservation areas and accelerating the development of old-growth characteristics in younger, more homogenous stands. Ultimately, it seeks to equip forest professionals with strategies to enhance the ecological functions of older forests within provincial forest lands. -

Using the Stand Development Protocol, the program evaluates previously harvested areas for tree species diversity, forest productivity, and health. It compares stands harvested before and after December 2005 to determine the effectiveness of forest regeneration practices. Supporting materials include detailed protocols and field cards for monitoring stand development and stump identification. -

Its primary purpose is to serve as a central reference and conceptual framework for forest professionals to design and implement silvicultural plans that move a stand from its current state to a desired future condition through planned interventions, known as stand development pathways. A crucial and recurring theme is the growing role of First Nations, including their traditional knowledge, values, and stewardship goals, which are integrated alongside ecological, social, and economic objectives. The document provides detailed guidance on technical aspects, such as managing for biodiversity, mitigating risks like windthrow and pests, and utilizing adaptive management for continuous improvement in forestry practices. -

The authors explain how human fire exclusion over the past 60 years has dramatically altered these forests, leading to increased fuel loads, higher tree density, altered species composition, and a greater risk of intense, large-scale crown fires. The documen then outlines four management options for these sites: continued fire suppression, controlled prescribed burns, mechanical fuel reduction, or a combination of these strategies, emphasizing the need to balance ecological, social, and economic considerations. Finally, the document highlights various ongoing research initiatives aimed at understanding fire regimes and developing integrated management solutions for these fire-adapted ecosystems. -
Results from a Correlated Curve Trend Experiment on Spacing and Thinning of Coastal Douglas-fir

The study, conducted over 28 years near Lake Cowichan, British Columbia, aimed to understand how different tree densities and thinning strategies affect various growth parameters like diameter, height, basal area, and total and merchantable volume. While acknowledging limitations due to site variation and a lack of replication, the report provides initial insights into managing Douglas-fir stands, emphasizing that higher density generally leads to smaller individual tree growth but greater overall stand volume, whereas thinning, especially heavy or early thinning, can positively influence tree size and merchantable volume. -
Growth and Yield 35 years After Commercially Thinning 56-year old Western Hemlock

The study found that while thinning d...This document details a long-term forestry study on the growth and yield of 56-year-old Western Hemlock stands in British Columbia, specifically examining the effects of commercial thinning over a 32-year period. The study found that while thinning did not significantly increase the overall cumulative yield, it did result in a larger average diameter for the remaining trees and an up to 8% greater usable total volume yield at the final harvest compared to unthinned stands. The decision to commercially thin these stands depends on whether a forester prioritizes a moderate increase in total volume or an improvement in the size and quality of the final harvested material. -
Growth and Yield 35 years After Commercial Thinning 50-year Old Douglas-fir

The study compared thinned and unthinned plots to analyze growth and yield metrics such as total volume, diameter, and mortality. While thinning led to a 12% increase in potentially usable total volume yield over the study period and produced larger diameter trees overall, it also resulted in an 18% reduction in total volume at final harvest compared to unthinned stands. The study suggests that commercial thinning provides earlier wood availability and larger trees, but does not significantly alter total gross annual growth or crop-tree size, offering valuable data for forest management models and strategies.
