Brackish Subtidal Aquatic Bed
System: Estuarine
SubSystem: Estuarine Subtidal

State Protection: Not Listed
Federal Protection: Not Listed

State Rarity Rank: S3S4
A State Rarity Rank of S3S4 means: Vulnerable in New York, or Apparently Secure - Vulnerable to becoming imperiled in New York, with relatively few populations or locations, few individuals, and/or restricted range; or uncommon but not rare in New York; may be rare in some parts of the state; possibly some cause for long-term concern due to declines or other factors. 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?
One of the common plants in brackish subtidal aquatic beds are coontails (Ceratophyllum spp.). The name originates from the shape of their leaves and branches, which resemble the tail of a raccoon. Their flowers have tiny green scales, and are located at the leaf base. Male and female flowers develop separately on the same plant. The male flowers occur in pairs on opposite sides of the stem while the female flowers are solitary.

State Ranking Justification [-]
There are probably far fewer than 50 occurrences statewide. Very few documented occurrences have good viability and very few are protected on public land or private conservation land. This community is restricted to brackish portions of estuaries in the state. The current trend of this community is probably stable to declining slightly due to moderate threats that include alteration of the natural hydrology and invasive species.
