Understanding the importance and processes behind partial disturbances: A foundation for silviculture and sustainable forest management

Sustainable forest management aims to conserve biodiversity and maintain ecosystem function while maintaining renewable resources. To achieve this goal requires knowledge of the attributes of natural disturbance regimes and disturbance impacts on forest composition and structure that can be used to guide management. The premise of this approach is that management to maintain historic forest structures and functions on current and future landscapes will maintain the habitat suitable for the biota adapted to the system. Most forest management practices in western Canada emulate or try to mimic the effects of major disturbances such as stand-replacing fires. On the other hand, little effort has been done to include partial disturbances in the landscape and stand level practices and emulate their effects while designing silvicultural systems. I will present results from two different studies in western Canada to illustrate the importance and the effects of partial disturbances on the dynamics of the stands and their implications for management. As common agents of change in the landscapes, partial disturbances are important drivers of the dynamics of the stands. Their effects on stands usually results in significant changes in the structure and composition. Understanding the processes behind disturbances and their implications is essential as it can be used as the baseline to design silviculture systems at the stand level and conduct sustainable forest management on the landscape.
