Results concluded that both the natural environment and pollutants of the marsh impacted sediment microbial communities, though each factor's effect can be difficult to distinguish without careful testing. Microbial communities were most affected by marsh size, elevation, and tides, followed by metals, then organic pollutants. Their analyses also discovered relationships between the concentration of pollutants, like metals, and specific

Even though the coastal marshes lack species diversity as a whole, there are differing plants between the marshes themselves. Vegetation structure and function can differ due to intertidal zone location, tidal movements of the marsh, and soil salinity.
