This document summarizes key findings from two long-term silvicultural research initiatives: the Montane Alternative Silvicultural Systems study and the Variable Retention Adaptive Management experiments. The MASS study, spanning 25 years, compared clearcutting to various alternative methods, revealing that tree growth was best in clearcuts, though other methods offered biodiversity benefits and paved the way for variable retention. The VRAM research explored different retention strategies, identifying windthrow as a significant challenge and demonstrating that retention provides crucial life-boating habitat for various species, with the amount, aggregation, and size of retained areas being critical factors. The research highlights that while increased canopy retention and dispersion can impact tree growth, these alternative systems offer important ecological advantages, particularly for understory vegetation and diverse species.

This document outlines the strategic approach to silvicultural systems in the Great Bear Rainforest, focusing on Ecosystem-Based Management. A central theme is the retention silvicultural system, which involves deliberately leaving trees and vegetation within harvested areas to maintain forest structure and biodiversity. The application of this system is context-dependent, influenced by the proportion of mature and old forest at both the broader landscape unit and immediate cutblock scales, with increased retention mandated where older forests are scarce. Additionally, the document addresses windthrow considerations at both landscape and stand levels, providing guidelines to mitigate damage while prioritizing the retention system in areas of lower wind hazard.

The core purpose of the CSC is to: 1) Accommodate the sharing of current forest management and technical silvicultural information to all forest practitioners and the public in coastal British Columbia through delivery of two annual workshops; a short, one or two day, winter information workshop and a longer summer field based technical workshop. 2) Support development of silvicultural expertise in students at the post-secondary level through providing of awards, where surplus workshop revenue exists.

This document present a strategy for the utilization and management of deciduous tree species, particularly red alder, big leaf maple, and birch, within the coastal forests of British Columbia. The paper outlines objectives for hardwood management, discusses different management strategies, and considers crucial aspects like timber supply, relevant legislation, and geographic considerations for successful implementation. It serves as a guide for forest professionals and decision-makers to support and expand hardwood management in the region, aiming to diversify the coastal fibre supply and ensure a sustainable flow of timber products.
