Overcoming critical recruitment bottlenecks limiting seedling establishment in degraded seagrass ecosystems: a systems approach to restoration

Seed-based restoration has been successfully used for decades in terrestrial ecosystems but has remained elusive for marine seagrass-dominated ecosystems. For seagrasses, the transitions from dispersed seed, seedling, recruit to reproductive adult are poorly understood. We propose a demographic approach to further understand these critical demographic transitions in the recovery and maintenance of seagrass meadows. In terrestrial vegetation restoration, recent demographic approaches allow identification of transitions most limiting to recruitment and successful establishment, crucial for effective restoration of seagrass meadows. This research explores a demographic approach for seed-based restoration of seagrasses.
