Stable Isotopes Reveal the Drivers of Post-Wildfire Natural Regeneration of Interior Douglas-Fir Seedlings in British Columbia.

Wildfires are increasing in frequency and severity due to climate change, posing challenges to forest ecosystems, including the southern interior of British Columbia, Canada. Interior Douglas-fir () is a species of great cultural, ecological, and economic importance, necessitating the investigation of post-wildfire regeneration amidst this changing wildfire regime. This study examines interior Douglas-fir seedling regeneration across three burn severity levels (low, moderate, high) 5 years post-wildfire at a site in interior British Columbia.
