Invasive Species Notes
Phragmites mono culture from channel bank to upland boundary.
Additional Comments (2024)
Phragmites dominated marsh and low upstream tidal extent indicate minimal tidal exchange and wetland is functioning as a freshwater wetland. Small patch of stunted phragmites just west of culvert may be extent of saltwater. Stop logs may be overly inhibiting incoming flow and tidal exchange. Removal of stop logs may help improve salt marsh health.
