By evaluating 17 different sites over 16 to 26 years, the authors analyze the critical trade-offs between individual tree size and total timber yield per hectare. The findings reveal that higher densities maximize total wood volume and biomass and lower densities produce thicker trees with less taper, though vertical height growth remains largely unaffected across all treatments. This document serves as a guide for forest managers to select optimal stocking levels based on specific commercial goals, such as high-value lumber production versus biomass for carbon credits. -

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. -

By using a stand-level water-balance approach, the researchers calculated the ratio of water availability to evaporative demand to establish drought tolerance thresholds for ten common tree species. The study concludes that many species face significant threats of stress and mortality on drier sites, whereas moist, water-receiving areas may serve as critical climate refugia for conservation. This document provides a practical framework for applying this data to silvicultural decisions, such as selecting resilient species for reforestation and identifying areas at higher risk for wildfires or invasive species. -
Suitability of Native Broadleaf Species for Reforestation in the Cariboo Area of the Southern Interior Forest Region
This document evaluates the long-term viability of planting native broadleaf trees as a reforestation strategy in British Columbia's Cariboo region. By tracking species like aspen, birch, and cottonwood alongside traditional conifers over a ten-year ...This document evaluates the long-term viability of planting native broadleaf trees as a reforestation strategy in British Columbia's Cariboo region. By tracking species like aspen, birch, and cottonwood alongside traditional conifers over a ten-year study period, the authors discovered that planted broadleaves suffered from poor survival rates due to wildlife browsing, frost, and competition from grass. While these deciduous trees naturally excel at enhancing soil nutrients and providing frost protection for understory seedlings, the study concluded that they are currently less reliable than conifers when manually planted. This document suggests that while broadleaves remain vital for forest biodiversity and health, their successful management in this region relies more on robust natural regeneration than on artificial cultivation. -

Because these mushrooms share a symbiotic relationship with ...This LMH #64 handbook outlines a strategic framework for compatible management, an approach that allows the forestry industry to simultaneously harvest timber and high-value pine mushrooms. Because these mushrooms share a symbiotic relationship with the roots of living, mature trees, traditional clear-cutting effectively eliminates their production for decades. To prevent this economic and ecological loss, the authors propose a four-step cycle involving habitat mapping, identifying overlap zones, implementing alternative silvicultural systems and long-term monitoring. By focusing timber operations on highly productive wood sites while preserving the well-drained, nutrient-poor soils where mushrooms thrive, land managers can achieve a winwin situation that supports both local biodiversity and diverse revenue streams. This handbook emphasizes that maintaining a landscape-level mosaic of varying forest ages is essential for the sustained commercial viability of non-timber forest products. -
