This webinar discusses operationalizing adaptive silviculture for climate change through a multi-site research network. The core purpose of the project is to provide forest managers with real-world, operational examples of integrating climate change adaptation principles into practice, specifically by fostering ecosystem resilience to uncertain futures. The research employs a consistent framework across various forest types, testing three primary adaptation strategies including resistance, resilience, and transition. The webinar details the work at the Minnesota pine site, highlighting local climate vulnerability to drought and the application of these three treatments: simple thinning for resistance, mixed-species restoration for resilience, and aggressive transition management using both native and novel, future-adapted species like Ponderosa pine.

This webinar details the core concepts of silvicultural systems, which are comprehensive approaches to forest management defined by three continuous elements: regeneration, tending, and harvesting. These systems are structured along a practical spectrum of harvest intensity, starting with low-disturbance selection methods suitable for shade-tolerant species and culminating in high-intensity treatments like clearcutting, which favor light-demanding species. The choice of technique, such as the multi-step shelterwood method or the more localized seed tree method, depends entirely on the desired future condition of the stand and the ecology of the target tree species. Successful silviculture is presented as both a science and an art, requiring creative application of various treatments, including intermediate thinning, to achieve specific outcomes.

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.
