- Dense phragmites monoculture
- Additional Comments (2024)
- A dense phragmites monoculture exists from upland border to upland border. Upstream end of culvert could not be accessed due to fencing and phragmites. Although marsh appears to receive little to no tidal exchange, there may be no opportunities to increase flow due to proximity of houses at a similar elevation to the marsh. Downstream end of culvert is within jetty. The tide gates are within manholes and could not be accessed.
