MonitoringLocationTypeName Wetland Estuarine-Emergent
MonitoringLocationDescriptionText The salt marsh empties into Cold Spring Harbor, an embayment of Long Island Sound, and is separated by a broad, high beach of gravelly sand from the Harbor on the eastern side. There is a welldeveloped tidal creek that runs the length of the marsh. The marsh is typified by significant stands of Spartina alterniflora and Distichlis spicata with other emergent estuarine plant species. Besides the seminal importance of salt marsh stands for critical habitat for plant and fish species, the high marshbeach berm area may serve as habitat for seaside sparrows, American oystercatchers, and piping plovers.
