Salt Marsh Field Assessment Results
Comprehensive field assessment dataPhysical Conditions Assessment

- Narrower than channel
- Channel Erosion
- None
- Sediment Deposits
- None
Blockages

Ecological Assessment
Habitat Observations
- Ecological Impairment due to Tide Gate
- Severe
- Crab Burrow Intensity
- None
- Ponding and Die-off Depressions
- None
- Phragmites Present
- Severe (>60%)
Invasive Species
- Upstream Invasive Species
- Yes
- Downstream Invasive Species
- Yes
- Invasive Species Notes
- Dense phragmites growth
General Comments
Dense phragmites growth with no marsh vegetation adjacent to channel. Marsh area appears to extend into yards and is actively mowed. Tide gate may be undersized or clogged and is retaining too much water. Downstream end could not be located and may be buried in sediment or debris.Habitat Transects
First Transect (50 yards upstream of tide gate)
No data
Second Transect (150 yards upstream of tide gate)
No data
Third Transect (300 yards upstream of tide gate)
No data
Restoration Potential
Assessment
- Salt Marsh Impairment due to Tidal Restriction
- Moderate
- Potential Extent of Marsh Restoration
- Moderate
- Implementation Feasibility
- High
- Restoration Priority
- High
- Recommended Improvement Type
- O&M and Infrastructure
Notes
Site shows moderate salt marsh impairment due to restricted tidal flow. Replacement with self-regulating tide gate could restore approximately 5-8 acres of degraded marsh habitat. Good access for construction equipment. Regional coordination completed with town DPW and conservation commission.Historical Records
