State Rarity Rank: S3
A State Rarity Rank of S3 means: Typically 21 to 100 occurrences, limited acreage, or miles of stream in New York State.

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?
Changes in salinity and temperature can influence migration patterns of fish within tidal creeks. Different species of fish are specialized for different levels of salinity. Fish that typically live in high salinity areas migrate into saltwater tidal creeks with high tide, following the increasing salinity level. Fish that spend most their time in the lower salinity areas of brackish or freshwater tidal creeks migrate farther upstream when the tides come in to avoid a sudden increase in salinity level. Some species of fish are able to tolerate low, mid, and high salinity areas. Some factors beyond salinity influencing the distribution of fish in tidal creeks include availability of food and presence of predators.

State Ranking Justification [-]
There are estimated to be about 60 occurrences statewide. The several documented occurrences have good viability and are protected on public or private conservation land. The community is restricted to salt marsh complexes along the seacoast in the Coastal Lowlands ecozone and along Long Island Sound in the Manhattan Hills ecozone. The current trend of the community is thought to be declining. The primary threats to the community are shoreline development, marsh ditching, channel dredging and filling, declining water quality, diking and impoundment, changes to tidal hydrodynamics, and invasive species.
