Description
The reference plant community is halophytic sedge wet meadow (Viereck et al. 1992) dominated by Hoppner’s sedge and at times Ramensk's sedge. Two plant communities occur within the reference state related to the frequency and duration of tidal inundation.
The vegetation modeled for this ecological site has limited data and is considered provisional.

Description
The reference plant community is halophytic sedge wet meadow (Viereck et al. 1992) with the dominant plant being alpine looseflower sedge. One plant community was identified within this alternate state. Compared to the reference state, vegetation and soils experience comparably less frequent tidal flooding and/or are flooded with brackish water in estuaries.
The vegetation modeled for this ecological site has limited data and is considered provisional.
