It draws upon existing research to discuss key factors influencing aspen regeneration, including the importance of removing apical dominance through disturbances like logging or fire to promote suckering. The presentation also details harvest considerations, such as the benefits of winter harvesting and the negative impacts of excessive canopy retention and soil compaction. The presentation explores the effects of various silvicultural practices and the interactions between aspen and coniferous species like spruce and pine, providing guidance on site selection and stockingregeneration surveys for successful aspen management. -
Alternative Silvicultural Systems and Harvesting Techniques for Caribou Habitat

Recognizing that clearcutting leads to habitat loss and increased predation on caribou through apparent competiti...This study investigates alternative forestry practices to mitigate the negative impacts of conventional clearcutting on caribou habitat. Recognizing that clearcutting leads to habitat loss and increased predation on caribou through apparent competition, the report reviews various silvicultural systems and harvesting techniques, analyzing their potential to maintain old-growth characteristics, limit forage for other ungulates, and minimize access. Through a literature review and expert interviews, the study assesses the applicability of methods like partial harvesting, understory protection, and intensive silviculture in the Alberta context, considering ecological, economic, and practical challenges. The report aims to identify strategies that balance timber harvesting with caribou conservation, acknowledging that site-specific conditions and careful implementation are crucial for the success of any alternative approach. -
Stand-Level Fuel Reduction Treatments and Fire Behaviour in Canadian Boreal Conifer Forest
This paper reviews the effectiveness of stand-level fuel reduction treatments in Canadian boreal conifer forests, specifically focusing on black spruce, jack pine, and lodgepole pine.

These treatments, which involve thinning trees, pruning lower branches, and removing understory vegetation, aim to mitigate the risk of fast-spreading, high-intensity crown fires that are naturally prevalent in these ecosystems. While these fuel treatments generally reduce modeled and observed fire behavior under low to moderate fire weather, evidence suggests they become ineffective under very high or extreme fire conditions, especially when combined with high surface fuel loads and the relatively short stature of boreal conifers. The authors highlight the need for further research into managing surface fuel loads, exploring alternative fuel configurations, and integrating these treatments with broader fire suppression strategies. -
Effects of Aspen Brushing on Lodgepole Pine Yields Using TASS 2.0776
This document details a study using the TASS II growth model to assess how different forest management techniques impact the timber production of lodgepole pine in mixed stands with aspen. Prepared for the Interior Broadleaf Working Group, the report...This document details a study using the TASS II growth model to assess how different forest management techniques impact the timber production of lodgepole pine in mixed stands with aspen. Prepared for the Interior Broadleaf Working Group, the report simulates various scenarios involving different densities of aspen and several treatments like brushing at different ages and herbicide application. The core purpose is to provide guidance on choosing the most effective brushing strategies to maximize conifer timber objectives in the Prince George Timber Supply Area, by analyzing the projected growth and yield of lodgepole pine under these varying conditions. The study meticulously examines factors such as site index, height growth, tree survival, and ultimately, the merchantable volume of pine achieved with and without intervention. -
