The salinity levels in brackish marshes can range from 0.5 ppt to 35 ppt. [2] Marshes are also characterised by low-growing vegetation and bare mud or sand flats. [3] Due to the variations in salinity, brackish marshes create a distinctive ecosystem where plants from either freshwater or saltwater marshes can co-inhabit. [4]
Technically, brackish water contains between 0.5 and 30 grams of salt per litre—more often expressed as 0.5 to 30 parts per thousand (‰), which is a specific gravity of between 1.0004 and 1.0226. Thus, brackish covers a range of salinity regimes and is not considered a precisely defined condition.

Tate leaves the marsh and Barkley Cove to attend college at the University of North Carolina at Chapel Hill, where he works in biology and protozoology labs under the guidance of professors.
Salt marsh showing salt pannes and ponds, spartina alternifolia and invasive phragmites communis in foreground. Brackish marsh panne variants occur in brackish marshes (short graminoid variant), one of the native dominant species is spike grass (Distichlis spicata), some brackish marsh pannes are dominated by the narrow-leaved cattail (Typha angustifolia) an invasive exotic species.
