The table below outlines the differences between grasses, sedges and rushes.
Smooth Cordgrass (Spartina alterniflora), also known as Saltwater Cordgrass, is very important to marsh health due to the large amount of organic material it contributes during decomposition. It is found in the intertidal zone of the marsh.
Saltmeadow Cordgrass (Spartina patens) is also referred to as salt marsh hay. It is found in the high marsh.
