The Farwell Canyon project was established within two Douglas-fir (Pseudotsuga menziesii) stands in the Very Dry Mild Interior Douglas-fir (IDFxm) biogeoclimatic subzone in the Cariboo Region, British Columbia in 2001. The project goals were to improve forage for wildlife and livestock (i.e., increase vascular plant cover), improve the growth of the residual stand by reducing inter-tree competition, shift the plant community composition to one that is more typical of open forest condition, and improve the resiliency of the stand to catastrophic fire. From a timber management perspective, the goal was to increase individual tree growth by logging and thinning while maintaining overall stand-level growth. To achieve these goals, treatment combinations of "modified" logging, pre-commercial thinning, and burning were applied to return the forest to a more open condition that is typical of Douglas-fir forest adjacent to grassland in the IDFxm. Four treatments were applied to one or both blocks: 1. No-treatment areas were established to serve as untreated controls for demonstration and comparison purposes. 2. The logging treatment used a fellerbuncher and grapple skidder combination to apply a "BDq" approach that left a residual stand basal area of about 15 m2/ha (B=residual stand basal area; D=largest-diameter trees; q=diminution quotient). The merchantable utilization was reduced to 12.5 cm diameter at breast height (dbh) for Douglas-fir. 3. The logging treatment was followed by manual thinning of juvenile stems (

This book presents the latest scientific and management information on multiaged silviculture, an emerging strategy for managing forestry systems worldwide. Over recent decades, forest science and management have tended to emphasize plantation silviculture. Whilst this clearly meets our wood production needs, many of the world's forests need to be managed far less intensively and more flexibly in order to maintain their natural ecosystem functions together with the values inherent in those processes. Developing multiaged management strategies for these complex forest ecosystems represents a global challenge to successfully integrate available science with sustainable management practices. Multiaged Silviculture covers the ecology and dynamics of multiaged stands, the management operations associated with regeneration, tending, and stocking control, and the implications of this strategy on production, genetic diversity, and stand health. It is primarily aimed at graduate level students and researchers in the fields of forestry and silviculture, but will also be of relevance and use to all professional foresters and silviculturists.

This document provides a brief, detailed summary of each presentation in the conference of Complex stand structures and associated dynamics: measurement indices and modelling approaches, in three-page popular summary format. Specifically, short, unedited syntheses were supplied by each author that summarize the essential information of the underlying research study, including scope, objectives, methods, results, references, and major conclusions. The primary purpose is to document the research studies presented for the benefit of the forest science and management communities and foster onsite discussion among conference participants.--Document.

The COWFISH model, developed and applied in selected Montana streams, was tested on 14 streams in Idaho, Nevada, and Utah, where it proved to have little value for predicting numbers of trout in watersheds grazed by livestock. The model holds promise for estimating the health of stream channels and riparian complexes.

The vast temperate rainforests of coastal British Columbia are world renowned, but much less is known about the other rainforest located 500 kilometres inland along the western slopes of the interior mountains. The unique integration of continentality and humidity in this region favours the development of lush rainforest communities that incorporate both coastal and boreal elements. In British Columbia's Inland Rainforest, scientists bring together, for the first time, a broad spectrum of information about this distinctive ecosystem. They also consider the ecological consequences of human activities in the rainforest and present strategies for its management and conservation.
