Project Description
The project was approved for invasive species management and ecological restoration. The
approved work is divided and managed within 3 zones; Zone 1 includes management of
approximately 11,950 sqft of Phragmites, Zone 2 includes management of approximately 3,500
sqft of sporadic Phragmites within marsh vegetation, Zone 3 includes installation of supplemental
native plantings within approximately 12,400 sqft of mixed invasive and native upland vegetation.
The resource areas present include salt marsh, bordering vegetated wetland, land subject to
coastal storm flowage and associated buffer zones.
Project Activities Completed during Assessment Period
August 19, 2025 – Assessment and treatment of Phragmites
September 25, 2025 – Site visit to assess invasive species management
October 1, 2025 – Assessment and treatment of Phragmites
Assessment of Current Site Conditions
At the time of assessment, it was concluded that ongoing maintenance and effective treatment
strategies have been mostly successful. No re-sprouting Phragmites (Phragmites australis) were
observed in any zones of the project area. This lack of regrowth indicates both effective and
successful control of this invasive species. Monitoring of the project area, along with minimal
maintenance using effective treatment methods should continue to ensure limited regrowth and
spread of Phragmites.
Anticipated Activities to be Completed Next Monitoring Period
• Continuing maintenance visits to control Phragmites.
