Description
Definition Tidally influenced riverine marshes with salinity levels less than 0.5, which are dominated by salt-intolerant, herbaceous species (e.g., Juncus sp., Eleocharis sp., and Zizania sp.). Non-tidal, palustrine, freshwater marshes are beyond the scope of CMECS. The list of Biotic Communities for this group is long: a few examples are provided below, and the complete list is available in Appendix F.
