Windows of opportunity: Thresholds to mangrove seedling establishment on tidal flats

Physical processes limiting colonization of bare tidal flats by pioneer mangrove species have commonly been described but not yet quantified. Understanding thresholds to early seedling establishment is critical for successful restoration and management of mangrove forests. We determined how seedling establishment of Avicennia alba Bl. is affect by the combination of increasing hydrodynamic forces and sediment dynamics. As the buoyant propagules of A. alba are dispersed by water, early establishment on bare tidal flats require propagules to quickly anchor to stay in place. Flume studies and field observations showed that 3 thresholds have to be passed until the seedling is successfully established: (1) stranded propagules need an inundation-free period to rapidly develop roots taht are long enough to withstand displacement by flooding, (2) roots need to become long enough t...
