Data underlying the publication: Pinpointing stage-specific causes of recruitment bottlenecks to optimize seed-based wetland restoration
In this study, we intended to make seed-based wetland restoration predictive and inform management by (1) seeking integrated experimental evidence generalizing stage-specific causative factors for demographic loss/mortality and (2) developing predictors oriented toward site-specific bottlenecks. Specifically, this study is focused on seed retention and seedling emergence, since they represent the most vulnerable life stages that follow sowing. Firstly, by means of large-scale field experiments, we tested how seed retention and seedling emergence were affected by varied management options (i.e., seed-planting depth and species selection) and a wide range of physical settings (i.e., elevation, hydrodynamic intensity, bed-level dynamics and sediment properties). Variable screening was then implemented to identify stage-specific governing factors. Secondly, the resulting insights and dataset were used to develop stage-specific predictive models using machine learning. Model experiments under various scenarios were then conducted to assess site-specific feasibility of potential seed-based restoration practices.
