Ecological resilience has become a focus of both research and management objectives in forest ecosystems. However, the classic concept of resilience as the rate at which a disturbed community or ecosystem returns to a pre-disturbance state is problematic under real-world conditions where multiple disturbances interact in space and time. In addition, press disturbances, such as climate change, gradually shift environmental conditions to a novel state, and may preclude a return to pre-disturbance conditions. Recently, a modern synthesis of resilience has emerged that recognizes the importance of maintaining functional continuity through time and at multiple spatial scales. This maintenance of function may include preserving functional traits within communities, controlling invasive species, promoting structural diversity in forests to maintain ecosystem services such as carbon storage, and developing landscape-scale management scenarios to mitigate the effects of climate change. All of these endeavors occur within a lens of public perception that may be slow to shift from a traditional focus on economics and recreation to the more abstract concept of ecological resilience. The goal of this session is to present a cross-section of work that examines ecological resilience in forests at scales ranging from communities to landscapes. While highlighting the complexity of maintaining desired structure and function in natural systems, we hope common threads will emerge that inform further research that will help guide management efforts.
