Ecological Assessment
Habitat Observations
- Crab Burrow Intensity
- Moderate (10-60% banks are dens
- Ponding Depressions
- Limited(<10% of marsh platform
- Phragmites Present
- Limited (<10%)
- Ecological Impairment
- Moderate
Invasive Species
- Upstream Invasive Species
- Yes
- Downstream Invasive Species
- Yes
- Invasive Species Notes
- Phragmites limited to occasional patches along upland boundary.
- Additional Comments (2024)
- No tide gate currently exists but is under consideration. Current marsh conditions show moderate restriction as evident by lack of low marsh community, erosion and higher stain marks on upstream side. Culvert may need widening. At a glance, house elevations appear to be high enough to support increased high tide level without need for tide gate but further analysis will be needed.
