The study assessed how a minimum riparian retention prescription impacted various stream characteristics. While the policy successfully met four of its five management objectives, it ultimately failed to maintain overall fish habitat values, particularly concerning the long-term supply of large woody debris, a significant decrease in litter fall, and an increase in stream temperatures due to reduced shade. Therefore, the authors recommend retaining all trees within 10 meters of the stream bank to better achieve desired environmental outcomes. -
Using Silviculture to Maintain and Enhance Grizzly Bear Habitat in Six Variants of the Prince George Forest Region

The analysis highlights key ecological differences, noting that mountain bears flourish in open, naturally gappy environments, while plateau bears struggle in dense stands that lack forage opportunities. To address this, the authors recommend using partial cutting systems and reduced tree density to create and maintain canopy gaps that maximize light penetration, stimulating the growth of critical shrubs, roots, and berries, and also suggests protecting features like high stumps and coarse woody debris. Furthermore, this document stresses the importance of minimizing human interaction by deactivating roads and retaining vegetation for security cover, especially near high-value riparian areas. This document provides an adaptive management framework to integrate wildlife needs directly into sustainable forest planning. -
Review of Glyphosate Use in British Columbia Forestry

It systematically explores the regulatory context governing herbicide use and the rationale behind glyphosate's application, contrasting it with other methods like manual cutting. The review then delves into the impacts of glyphosate on various ecological values, including biodiversity, soil and water quality, climate change considerations, wildfire dynamics, First Nations interests, and public use perceptions. Finally, it assesses the implications for timber supply and discusses managing forests for multiple values, culminating in recommendations for future research, data collection, communication, and policy development.
