Biological monitoring at the reserve was initiated by the establishment of a sentinel site on Prudence Island with the purpose of gathering and analyzing in-depth data to study the effects of sea-level change and inundation on tidal wetlands.  The results of this research, together with the long-term monitoring data collected, provides a strong, science-based foundation to inform programs, policy makers and managers in charge of making coastal management decisions.
