Community Type: tidal brackish marsh
Community Description: Irregularly flooded, slightly brackish marsh adjacent to a small stream which flows into Mill Creek in Supawna Meadows NWR. Marsh is co-dominated by Typha angustifolia, and Phragmites australis. The area surveyed has been treated to reduce the Phragmites population - successfully. The area further south, which has not been treated, appears to be a monoculture of Phragmites. Dominant species in the plot are Typha angustifolia and Echinochloa spp. High tide marks on the vegetation stems are the only evidence of community processes. No soil sampling was done, but surface soil apperaed to be black muck. Marsh is quite diverse and has a good number of non-graminoid species. The site should be evaluated earlier in the season.
