The existing native plant community on the bank will be conserved by 1) removing the invasive plant pressure and 2) reducing the severity of erosion at the toe of bank. Installation and planting of the reinforced marsh will also provide additional native plant species where none exists. ACTIVITIES TO DATE: 2024 • The reinforced marsh installation was completed in March. Access was accomplished from the top of bank and no barge was required. • Initial management of the targeted non-native and State-listed plant species was completed in March. • Planting of the specified native species into the reinforced marsh was completed in June. • Conducted follow-up management of the invasive and non-native plant species via the approved protocol methods. 2025 • Planting of additional native species on Coastal Bank. • Conducted follow-up management of the invasive and non-native plant species via the approved protocol methods. • Continued monitoring the reinforced marsh and health of the native plantings. • Submitted the 2025 monitoring report. PROJECT CONDITIONS: Several site visits have been conducted throughout the 2025 season to assess the condition of the reinforced marsh and plantings. The reinforced marsh has maintained good structural condition through its second growing season since its installation. The planted native species within the reinforced marsh have established very well. Smooth cordgrass (Spartina alterniflora) and spike grass (Distichlis spicata) have done exceptionally well where the highest levels of sunlight have reached the installation. Establishment of the planted marsh grasses would be assisted by greater amounts of sunlight. The planted native species will be closely monitored during the 2026 growing season. Management of the targeted species on the bank has been very effective at reducing the invasive plant pressure. Maintenance visits during the 2026 growing season will continue to management of the re- sprouting non-native plant species. 2026 ANTICIPATED ACTIVITIES: • Conduct follow-up management of the invasive and non-native plant species via the approved protocol methods. • Continue monitoring the reinforced marsh and health of the native plantings. • Submit the 2026 monitoring report. 28 Lots Hollow Road | Orleans, MA 02653 Tel:(508)255-1113 | Fax:(508)255-9477 TMTM PHOTO DOCUMENTATION ON ATTACHED PAGES: 2 Image along the bottom of the bank looking north towards the stairway. The reinforced marsh is in excellent condition and the planted native species have established quickly. Image along the bottom of the bank from the stairs, looking north. The reinforced marsh is in excellent condition on this portion of the bank. The planted native species in and above the reinforced marsh have established well. 3 Image of the southern half of the bank from the stairway. The English ivy density has been drastically reduced and the native understory plant species should begin to re-colonise during the 2025 growing season. The addtional native plantings are establishing during the first growing season Image of the northern half of the bank from the stairway. No black locust saplings or sprouts were observed. Removing the invasive plant pressure have conserved the existing native grasses and shrubs on the Coastal Bank.
