Development of a Drought Risk Assessment Tool for British Columbia Forests Using a Stand-level Water-balance Approach

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. -
Harvest Intensity Effects on Carbon Stocks and Biodiversity Are Dependent on Regional Climate in Douglas-fir Forests of British Columbia

The study compared the effects of clearcutting, varying levels of partial tree retention, and no harvesting across different climatic regions in British Columbia's Douglas-fir forests, ranging from humid to semi-arid. The central finding is that the intensity of harvesting significantly influences carbon storage and biodiversity, but importantly, the magnitude of these effects is strongly linked to the regional climate.
