Habitat restoration and the recovery of metacommunities
Journal of Applied Ecology(2023)
摘要
Ecosystem restoration is becoming a widely recognised solution to the biodiversity crisis. However, there is a gap between restoration science and practice. Specifically, we lack a theoretical framework which would improve our understanding of ecosystems’ recovery and allow us to optimise restoration design. Here, we narrow this gap by developing spatially explicit metacommunity models and studying the recovery dynamics of communities during restoration. We show that community response depends on how damaged the landscape is prior to restoration, with highly fragmented landscapes imposing greater challenges to community recovery. In such cases, we found that the recovery depends on the type of interaction and the structure of the interaction network. Finally, we demonstrate that community recovery can be maximised with careful spatial planning. When recovering communities composed of antagonistic interactions, restoration should target areas adjacent to the most species-rich sites. In the case of mutualistic communities, the same strategy should be adopted in the short-term, whereas in the long-term, restoration should be extended to sites that improve the overall connectivity of the landscape. Our results highlight the importance of considering interactions between species and spatial planning in restoration projects.
