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]

Brackish water, sometimes termed brack water, [1] [2] is water occurring in a natural environment that has more salinity than freshwater, but not as much as seawater. It may result from mixing seawater (salt water) and fresh water together, as in estuaries , or it may occur in brackish fossil aquifers .
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.
Fritchie Marsh is an area encompassing 6,291 acres of intermediate and brackish marsh [1] located approximately three miles to the southeast of Slidell, Louisiana, USA.This wetland was originally documented as a freshwater marsh but has since been converted to a mixed intermediate and brackish marsh, and it threatens to become open salt water.
Intertidal marshes; includes saltmarshes, salt meadows, saltings, raised salt marshes, tidal brackish and freshwater marshes; Intertidal forested wetlands; includes mangrove swamps, nipa swamps, tidal freshwater swamp forests; Brackish to saline lagoons and marshes with one or more relatively narrow connections with the sea
It includes unspoiled brackish marsh and small pine islands adjacent the south bank of the James River. The area is dominated by vegetation such as marsh mallow, smartweed, saltmarsh cordgrass, and black needlerush, with loblolly pine as the most common tree species.
