Modelling Forest Harvesting Effects on Maximum Daily Peak Flow at Upper Penticton Creek

Using a sophisticated hydrological model, the study simulated various clearcutting scenarios to understand how the removal of forest cover influences the magnitude and frequency of high flow events. The findings indicate that forest harvesting consistently increases peak flows, with larger, less frequent events showing a more significant response, though the predicted increases were less than 50% even with complete forest removal. The study highlights the importance of watershed characteristics like topography and size in determining the extent of these changes and emphasizes the ongoing need for research to improve water resource management in forested areas. -
Fort St. John Pilot Project Sustainable Forest Management Plan
This document outlines how participating forestry companies and BC Timber Sales intend to manage forests sustainably, aiming to balance ecological, economic, and social values.

The plan incorporates a Canadian Standards Association certification process and emphasizes a landscape-level approach to forest management, considering natural disturbance patterns. Key components include establishing values, objectives, indicators, and targets developed with public and Indigenous input, along with specific strategies for timber harvesting, reforestation, road access, wildlife habitat, and engagement with First Nations and the public. The SFMP serves as a guiding document for operational planning and continuous improvement in forest management practices within the defined area. -
Windthrow in Partially Cut Lodgepole Pine Forests in West-Central British Columbia
This extension note details a study on windthrow in partially cut lodgepole pine forests in west-central British Columbia.

The research was motivated by concerns that partial harvesting, a strategy used to manage habitat for the blue-listed northern caribou, might increase windthrow to levels that negatively impact caribou habitat, timber supply, and forest health. The study compared windthrow rates in different partial cutting methods to uncut control areas over a 5. 3-year post-harvest period to assess the risk of increased windthrow associated with these silvicultural systems. -
Reforesting Dry Sites in the Thompson Okanagan Natural Resource Region
This document is a comprehensive guide to address the increasing challenges of establishing healthy forests on drought-prone lands.

Recognizing the impact of climate change and high seedling mortality, the report meticulously examines current silviculture practices and relevant research to identify best management practices for improved regeneration success. It provides a drought risk key for practitioners to classify sites and recommends specific treatment regimes encompassing planning, harvesting, mechanical site preparation, planting considerations, and post-planting surveys. The purpose of this guide is to offer practical, experience-based guidance to forest managers in the Thompson Okanagan region to enhance the resilience and successful reforestation of dry sites facing heightened drought risk. -
Comparing Clearcutting and Alternatives in a High-Elevation Forest Early Results from Sicamous Creek
This extension note reports on the early findings of the Sicamous Creek Silvicultural Systems project, a long-term study comparing different forestry practices in high-elevation forests of British Columbia. The central theme is the evaluation of clea...This extension note reports on the early findings of the Sicamous Creek Silvicultural Systems project, a long-term study comparing different forestry practices in high-elevation forests of British Columbia. The central theme is the evaluation of clearcutting versus alternative harvesting methods, such as small patch cuts and individual tree selection, regarding their impacts on various ecological and economic factors. The purpose of this note is to summarize initial results concerning harvest costs, regeneration, soil conditions, microclimate, and biodiversity, ultimately aiming to inform more ecologically diverse and sustainable forest management in these sensitive ecosystems.
