This paper investigates how different forest management strategies impact the resilience of forests facing climate change, specifically a mountain pine beetle outbreak in British Columbia. The authors use a retrospective simulation approach from 1980 to 2060 to compare business as usual practices with two alternative strategies: one focused on increasing the diversity of replanted trees, and another that combined early harvesting of susceptible pine with diversified reforestation. The study assesses resilience by examining ecological factors like growing stock and tree species diversity, alongside socio-economic indicators such as timber flow stability and net revenue, concluding that proactive management enhancing diversity and reducing high-risk species leads to greater overall forest resilience in the face of climate-related disturbances.

This document investigates how partial harvesting strategies, designed to enhance mule deer habitat and allow timber extraction in British Columbia's dry Douglas-fir forests, impact complex interactions with natural disturbances like insect outbreaks and wildfires. The study, spanning 30 years, found that while short-term harvesting altered forest structure and reduced the immediate risk of crown fires and Douglas-fir beetle infestations, many of these structural and susceptibility changes reverted over the long term. The removal of harvesting residuals proved more significant in mitigating long-term disturbance risks, particularly for Douglas-fir beetles and intense surface fires, than the time elapsed since the treatment itself. The authors conclude that sustainable forest management integrating timber extraction and mule deer habitat conservation is achievable if partial harvesting occurs at intervals of 30 years or less and residuals are promptly cleared.
