In 2023, Long Island Sound Study, New York Sea Grant and Warren Pinnacle, in partnership with committed municipalities and marsh-conservation groups/organizations, developed a Plan to understand the benefits, threats and recommended conservation actions at seven focal areas across the harbors. The goal of the Plan is to inform local municipalities and marsh-conservation groups as to where they might focus their conservation efforts to maximize the conservation of marsh ecosystem services under sea-level rise conditions. This process brought together a diversity of stakeholders to develop a cohesive strategy for seven focal areas across Oyster Bay and Cold Spring Harbor: Frost Creek, Mill Neck Creek, West Shore Road, Bayville Bridge to Centre Island, Centre Island, Shore Road, and Lower Cold Spring Harbor. The partners will now work to implement the recommendations in the plan.

St. John’s Episcopal Church (lower Cold Spring Harbor) and Village of Lattingtown (Frost Creek) were 2024 LIS Resilience Planning Support Program awardees. Their projects will build off the Oyster Bay & Cold Spring Harbor marsh conservation plan and develop specific recommendations to enhance and restore marsh habitat in lower Cold Spring Harbor and Frost Creek.

The purpose of this project was to mitigate 450 ft of coastal erosion on the Long Island Sound. A part of Crab Creek was moved further inland, thus allowing for beach and dune migration over time. New rock sills, plants, and sand sills were also positioned along the shore.

This public greenspace was suffering from mosquito overpopulation, invasion from Phragmites, and poor tidal/stormwater drainage. The Wetland’s Habitat and Mosquito Management Program (WHAMM) created a new drainage area and tunnels, while also eliminating invasive plants. Then organizations and volunteers banded together to remove and replace invasive plant species with native plants.

This project restored 46 acres of the Great Meadows Marsh in Connecticut that was degraded from dredge material that was dumped on site, poor drainage, and sea level rise. The marsh was also overrun with invasive plants and mosquitoes. A controlled fire was started to kill the invasive reeds growing in the marsh. Then a construction crew removed invasive plants and the dumped dredge material. Lastly, channels were carefully dug for tidal flushing which will allow the marsh to keep pace with sea level rise. Soil hummocks were constructed for Salt Marsh Sparrow habitat. Now the area continues to be monitored, assessed for resiliency, and provides a field for innovative solutions to be tested in.
