Managers have long been grappling with how to ensure that ecosystems maintain their desired states in the face of global changes. Particularly concerning is the likely interaction between slow variables, such as vegetation management or nutrient additions, and extreme discrete events such as extended drought, tropical storms, and intensive fires that have and will continue to become more frequent under climate change. The interaction of these pressures has at times led to threshold behavior and ecological collapse. Thus, building the resilience of ecosystems has become a management imperative. Degraded ecosystems may be prone to ecological collapse when attributes imparting resilience are lost, such as species diversity. Restoration ecologists are developing a suite of tools to support and increase resilience of degraded sites through restoration. Because of logistical and cost constraints, restoration projects are often embedded in a larger landscape that has undergone widespread alteration and experiences similar stresses as the project area. Increasingly, examples are arising of projects that restore at relatively small scales with the strategic purpose of benefiting resilience at the landscape-level. A recent review by our opening speaker has touched on the three complementary ecosystem characteristics that drive overall resilience: resistance to particular known disturbances, recovery ability post-disturbance, and ecosystem adaptability. These three attributes are being used to inform strategic, small-scale restoration choices that create maximum benefits at broader scales. In this symposium, speakers will be asked to consider three primary mechanisms of resilience: resistance, recovery, and adaptability. Speakers will then delve into the mechanisms, discussing their roles in landscapes and giving examples of how small-scale restoration management can influence landscape-scale outcomes with respect to the mechanisms. The final talk will bring together all three mechanisms into a single, watershed-scale project in the Louisiana Delta. It will review and illustrate how to integrate multiple resilience goals into a single restoration plan and will discuss the incorporation of socio-ecological stakeholders and outcomes.
