This document details a study evaluating alternative silvicultural systems designed to improve the reforestation of spruce-dominated boreal mineral wetlands in Alberta. Researchers compared narrow alternating strip-cuts and patch clear-cuts against uncut forest controls to determine which method best mitigates the common challenges of excessive waterlogging and competitive grass ingress. The findings indicate that the strip-cut system provided a superior microclimate and higher seedling survival rates, particularly for white spruce planted on mounded microsites. This study concludes that prompt postharvest site preparation and the partial retention of the overstory are essential for successful, long-term conifer regeneration on these sensitive, wet sites.

Out On A Limb is a series that uplifts trailblazers in BC communities who are leading innovative management practices for the betterment of the forests of tomorrow. This episode of Out on a Limb features Li?l?wat Forestry Ventures and highlights their unique holistic approach to forest management. Join Klay Tindall, General Manager, and Jordon Gabriel, Forestry Technician, as they reflect on how innovation is built into the very core of their approach to forest management, stressing the importance of adaptability and learning from the land. They offer advice to those considering similar innovative practices in forestry management and emphasize the use of local knowledge to manage the forest for a variety of values.

Out On A Limb is a series that uplifts trailblazers in BC communities who are leading innovative management practices for the betterment of the forests of tomorrow. This episode of Out On A Limb spotlights West Fraser's work around Quesnel, supported by expertise from Government of BC biologists and Esk'etemc Lands and Resources Guardians. Join Janelle Hale and Laurel La Riviere as they explain their approach to managing fisher habitat using the Fisher Habitat Retention Spatial Data and Tool. Sandra Frey, Carnivore Conservation Biologist with the Government of BC, also shares an accessible overview of fisher behaviour, their habitat needs, and how forest practitioners can use the Fisher Tool to guide their prescriptions. Esk'etemc Guardians, Eric Dick, Tracer Weingart and Dale Johnson share their perspectives on fishers and the importance of monitoring and conserving fishers.

Out On A Limb is a series that uplifts trailblazers in BC communities who are leading innovative management practices for the betterment of the forests of tomorrow. In this episode of Out on a Limb, the SIP joins Alkali Resource Management, which is 100% owned by Esk'etemc First Nation, and project partners from the Government of BC to learn more about the impacts and benefits of ARM's innovative approaches just south of Williams Lake, BC. Francis Johnson and Julian Paul walk through some ways ARM aims to create resilience in stands that possess dense understories of small trees, increasing wildfire risk, and decreasing suitability as wildlife habitat using partial harvest with clumpy spacing and prescribed burning to restore forest health and revitalize cultural uses and values. This collaborative project evaluates the efficacy of ARM's treatments on understory vegetation and wildlife use, wildfire risk, disturbance agents, and overall forest integrity and resiliency. By blending Indigenous stewardship, applied research, and on-the-ground treatments, the trial is generating valuable insights into how these forests can become more resilient to disturbance while supporting mule deer winter range, biodiversity, and culturally important plants.

Out On A Limb is a series that uplifts trailblazers in BC communities who are leading innovative management practices for the betterment of the forests of tomorrow. In this episode of Out on a Limb, the SIP joins Harrop-Procter Community Forest to learn about their innovative approach to anticipate and adapt to climate change impacts. Harrop-Procter CF has spent the past 15 years adapting their forest management approach to respond to climate change impacts on their forest and surrounding landscape. Using a risk assessment approach, they are able to identify areas with varying risk to climate change and prioritize management actions. Erik Leslie, Forest Manager at Harrop-Procter, unpacks the three types of Operations Strategies he employs using his climate adaptation framework: Resistance, Resilience, and Transition. the SIP joins him in the field to visit three sites where these strategies have resulted in specific treatments to make the site either resistant, resilient, or completely transitioned on a new trajectory. Erik shows us how managers can integrate climate science and risk assessment into practical forestry decision making.

This case study evaluates how different logging and fire management techniques can simulate natural disturbance patterns in Montana's lodgepole pine forests. The authors compared two specific shelterwood silvicultural treatments: one where remaining trees were spread out evenly, and another where they were kept in concentrated groups. The study found that prescribed burning effectively reduced the hazardous fine-fuel loading created by harvesting and the even distribution method led to much higher levels of unintentional tree mortality than the grouped approach. The authors suggest that grouped retention may be a more resilient strategy for restoring forest structure because it better protects delicate overstory trees from both fire damage and windthrow.

This document investigates how to balance forestry interests with the survival of mountain caribou in British Columbia, specifically by moving away from clearcutting silvicultural systems. Because caribou rely on arboreal lichens found in old-growth forests for winter sustenance, traditional logging methods that remove all tree cover effectively destroy their primary food source and increase predation risks. The authors propose and test selection silvicultural systems, such as single-tree or group harvesting, which aim to extract timber while perpetually retaining stand characteristics necessary for caribou habitat. Through field trials, the study monitors how these partial-cutting techniques affect lichen biomass and growth rates, concluding that such methods should be integrated into a broader landscape-level strategy that includes designated no-harvest refugia.

This paper details the establishment and early findings of the Montane Alternative Silvicultural Systems partnership, formed to investigate alternatives to clearcutting in the high-elevation old-growth forests of Vancouver Island. The study compares the operational costs and biological impacts of Uniform Shelterwood, Green Tree Retention, and Patch Cuttings to traditional clearcutting and an old-growth control. Initial results highlight differences in harvesting expenses, windthrow, site disturbance, nutrient cycling, understory vegetation response, and coniferous regeneration, emphasizing the complexity of balancing timber harvesting with ecological sustainability in these montane ecosystems.

This case study details the adoption and implementation of variable retention, a new forestry approach by Weyerhaeuser's British Columbia Coastal Group. Recognizing the ecological importance of residual structures after natural disturbances, VR aims to sustain old-growth forest characteristics within harvested areas by leaving behind live and dead trees. The paper outlines the origins of VR, the establishment of different landscape zoning strategies, and the practical considerations for its application, including harvesting techniques, economic impacts, and silvicultural adjustments for regeneration, emphasizing a commitment to biodiversity conservation alongside timber production.
