Protecting & Restoring Long Island's Peconic Bays
Learn what PEP is doing to address the priority issues in the Peconic Estuary!
Contamination of Peconic Estuary waters by bacteria and other pathogenic organisms may result in the closure of bathing beaches and the closure of shellfish beds for human consumption; thus impacting economic and recreational activities on the East End. The Peconic Estuary Program is working with its partners to reduce pathogen pollution from stormwater runoff and wastewater.
Subwatershed Management Plans
To decrease the amount of pollutants entering the water via stormwater we need to do our part to change what we do on land. PEP has worked to establish subwatershed management plans to address the pathogen loads to waterbodies troubled with pathogen pollution, and to date has created 12 subwatershed management plans.
These plans focuses on identifying cost‐effective structural and non‐structural practices to reduce overall pollutant loadings (i.e. bacteria, sediment, nutrients) and runoff volume to the subwatershed. Successful implementation of these plans is expected to help reduce stormwater runoff pollution and improve overall water quality conditions. This should in turn improve shellfish harvesting capacity, eelgrass habitat, and degraded marsh areas.
PEP established a collaboration of East End municipalities to share resources and work together on projects to reduce stormwater runoff, reduce pollution from septic system discharges, agricultural and residential fertilization, groundwater flows, illegal dumping, floatable debris and boat waste.

PEP protects and restores priority habitats; including critical areas that support submerged aquatic vegetation, tidal wetlands and fish habitat, that are threatened by the alteration of the natural landscape from factors such as development, pollution and climate change.
PEP Habitat Restoration Plan
In 1997 the Peconic Estuary Program Habitat Restoration Workgroup was formed and charged with identifying important Peconic natural habitats with enhancement or restoration potential, developing overall habitat restoration goals, and identifying and prioritizing potential restoration projects. The end product was the “Habitat Restoration Plan for the Peconic Estuary” dated December 2000. This Habitat Restoration Plan was subsequently updated in 2009 and again in 2017. Over the years, the Peconic Estuary Program has completed projects to restore a variety of habitat types, including beaches/dunes, grasslands, diadromous fish habitat, eelgrass, and wetlands.
PEP Eelgrass Monitoring and Management Plan
The decline of eelgrass (Zostera marina L.) in the Peconic Estuary over the last 70 years has contributed to the degradation of the estuary as a whole. The PEP has undertaken several initiatives to advance the protection and management of eelgrass in the Peconic Estuary.
Since its inception, the PEP has supported a Long Term Eelgrass Monitoring Program conducted by Cornell Cooperative Extension’s Marine Program. This monitoring program, has focused on collecting data pertaining to the health of the eelgrass beds at various sites throughout the Peconic Estuary. PEP also conducted aerial surveys of eelgrass in 2014 to map and identify changes in the extent of the resource over time.
In 2009, an Eelgrass Management Plan was adopted in 2009 to provide a nesting ground for discussion, theories, and new actions necessary to minimize impacts to eelgrass and to provide a suitable environment for eelgrass to exist.
The status and trends of living resources are closely related to the amount of land preserved in the Peconic Estuary. Benefits to land protection include preserving unique species and natural communities, and controlling nutrient and pollution loads to the Estuary. In addition, the public has exhibited a strong attachment to the natural resources and amenities provided by the Peconic Estuary region.
The Peconic Estuary Program has developed a Critical Lands Protection Strategy (CLPS) that outlines land still available for development that also meet certain criteria used to determine land protection priorities. The Program shares this information with State and local agencies so that it can be used to make land acquisition decisions. PEP is currently updating the Critical Lands Protection strategy to account for climate change and rising seas (see Climate Change section).
Since 2006, approximately 2,443 acres of land have been protected in the Peconic Estuary watershed. The most significant source of funding for land protection is the Community Preservation Fund (CPF), administered by the five East End towns. This funding is supplemented by County and State governments, and not-for-profit organizations (especially The Nature Conservancy and the Peconic Land Trust).
PEP is working to ensure that climate change is considered in all PEP decision making, including the prioritization and selection of sites for restoration and acquisition. Maintaining and increasing living shorelines, updating the critical lands protection strategy, and educating stakeholders about the impacts of climate change on estuary resources will be priorities.
Peconic Estuary Climate Vulnerability Assessment
Currently PEP is completing a risk-based assessment, to account for future sea level rise, storm inundation and erosion potential. Based on the results of this assessment, a Climate Ready Action Plan will be developed to address prioritized climate change risks and vulnerabilities in the Peconic Estuary watershed and the Shinnecock Indian Nation. The intent of the Action Plan will be to identify methods to integrate climate change consideration into all phases of planning, design, and execution of the Peconic Estuary Program.
Considering Climate Change in the Critical Lands Protection Strategy
PEP is also completing an update to the Peconic Critical Lands Protection Strategy (CLPS), originally completed in 2004, to take into account climate related variables, specifically sea level rise, in order to update land acquisition priorities. This project will result in the protection and acquisition of lands the will continue to preserve and improve water and habitat quality in the face of rising sea levels and increased temperatures. It will allow for the natural inland migration of critical wetland habitats as sea level rises and preserve living shorelines in an environment where shoreline hardening is likely to become increasingly common. The information resulting from the new strategy will serve as an important tool for New York State, Suffolk County, and local agencies.
