The contractor assessed several solutions aimed at restoring natural tidal dynamics to increase water flow and 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, and emphasizes adaptive planning through interagency collaboration and engineering-informed restoration.
The Paul Stoutenburgh Preserve (PSP) in Southold, NY is experiencing in the ecological impacts in 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 and partially obstructed culverts along the water’s path into the area.
Previous culvert infrastructure severely limited tidal exchange. Restoration benefits are contingent on full tidal pathway functionality.
Preferred Restoration approach
Culvert replacement for hydrological restoration would enhance tidal flow to the PSP wetland, increase salinity and water levels, reduce conditions favorable to Phragmites.
Infrastructure-based restoration
This approach uses targeted infrastructure upgrades to naturally restore tidal dynamics, representing a minimally invasive, cost-effective alternative to dredging or extensive regrading.
Ecological and community benefits
Ecological and community benefits to the surrounding area include restored wetland ecology and improved tidal flow that will increase wetland resilience as well as restore native plant communities.
Adaptive planning and collaboration
Highlights the importance of interagency communication, jurisdiction clarity, and engineering-driven ecological restoration.
