The purpose of this project was to develop a more complete understanding of the vegetation communities within Maryland's Herbaceous Tidal Wetlands. This was accomplished by developing a vegetation community classification for these wetland types. This classification will be used to augment the ongoing Maryland Vegetation Classification (Berdine 1998), the Community Alliances and Elements of the Eastern Region - 2nd Draft (Sneddon et al. 1996), and The National Vegetation Classification System (Grossman et al. 1998). With this classification, exemplary examples of each community type were identified and described as reference sites. The information gathered in this project will be used to complement other projects studying tidal wetlands in the eastern United States.
