The Paul Stoutenburgh Preserve (PSP) in Southold, NY, is experiencing the ecological impacts of tidal restriction, leading to the dominance of Common Reed (Phragmites australis), a highly invasive species. These conditions are largely due to limited tidal flow from the Peconic Estuary, caused by undersized & partially obstructed culverts along the water’s path into the area. The contractor assessed several solutions aimed at restoring natural tidal dynamics to increase water flow & deter Phragmites spread. Infrastructure-based restoration uses targeted upgrades to naturally restore tidal dynamics, offering a minimally invasive, cost-effective alternative to dredging. This approach improves wetland resilience, supports native plant communities, & emphasizes adaptive planning through interagency collaboration & engineering-informed restoration.
