This extension note serves as a practical guide for forest managers in coastal British Columbia. It introduces the variable retention silvicultural system, a method focused on retaining important ecological features like old trees and snags during harvesting to support biodiversity and habitat connectivity. The aid outlines key considerations for planning and implementing VR, including identifying biological anchors, setting retention targets based on landscape context and management objectives, and managing potential risks such as windthrow and dwarf mistletoe, ultimately aiming for sustainable forest management that balances timber harvesting with ecological values.

This document details the establishment of a significant forestry experiment called Silviculture Treatments for Ecosystem Management in the Sayward. The core purpose of STEMS is to compare different forest harvesting and management techniques beyond traditional clearcutting in second-growth Douglas-fir stands. This comparison evaluates their impacts on forest productivity, economics, and public perception, aiming to provide scientific data for making informed decisions about sustainable, multiple-use forest management. The project replicates a similar study in Washington State to enhance the reliability and broader applicability of its findings, addressing the increasing demand for forestry practices that balance timber production with ecological and social values.
