Coastal Salt Pond
Coastal salt pond on Fisher's Island Gregory J. Edinger
System: Estuarine
SubSystem: Estuarine Intertidal

State Protection: Not Listed
Federal Protection: Not Listed

State Rarity Rank: S1S2
A State Rarity Rank of S1S2 means: Critically Imperiled or Imperiled in New York - Especially or very vulnerable to disappearing from New York due to rarity or other factors; typically 20 or fewer populations or locations in New York, very few individuals, very restricted range, few remaining acres (or miles of stream), and/or steep declines. More information is needed to assign a single conservation status.

Global Rarity Rank: G4
A Global Rarity Rank of G4 means: Apparently secure globally, though it may be quite rare in parts of its range, especially at the periphery.

Did you know?
Coastal salt ponds (sometimes called lagoons) are actually estuaries where fresh water from rivers and streams meets the salt water from the ocean. At times, the ponds are separated from the ocean by sand that was gradually deposited by wave action. During a storm surge, like what happens during a hurricane, this sand barrier is opened up and the ponds are directly connected to the ocean again. The plant and animal life in these ponds can change drastically depending on the salinity of the water. These ponds can be the nurseries for many species of fish and shellfish. They are also a favorite stopping point for all types of migratory birds (

State Ranking Justification [-]
This community only occurs on the coastal plain of New York. There are very few, small (low acreage) occurrences currently mapped. Many documented occurrences have good viability and are protected while others are threatened by coastal development. The current trend for this community is probably stable for occurrences on public land, or declining slightly elsewhere due to moderate threats related to development pressure or alteration to the natural hydrology. This community has declined moderately to substantially from historical numbers likely correlated with an increase in residential and commercial development.
