By reconciling theory with data and synthesis we increase our understanding and predictability of secondary forest succession and how it can be used as the natural engine for ecosystem restoration.

Tropical secondary forests cover 25% of tropical forest landscapes. They have a great potential to recover biodiversity, carbon, and water cycling, provide a range of services to local people, and are the basis for ecosystem restoration. Advancing our understanding of secondary succession is urgently needed, given global commitments to restore 350 million ha of forest by 2030 and to support the UN decade on Ecosystem Restoration. Yet, the spatial and temporal patterns of tropical forest succession are not fully understood, let alone predictable. In this symposium we focus on SF that regrow after complete forest removal for agriculture or pasture use. After agricultural abandonment they regrow nearly from scratch, thus providing an ideal model system to study fundamental ecological processes such as community assembly, succession, and resilience. We will combine conceptual synthesis and data-driven analyses to elucidate the demographic and environmental drivers of tropical forest succession from local to continental scales. This will be complemented with presentations on application and restoration, on how we can manage secondary succession as the natural engine of forest restoration, and design effective forest restoration strategies. Overall, this symposium would thus integrate science with restoration and conservation issues, addressed from both fundamental and applied perspectives.
