Restoration of the Great Meadows Marsh

This project restored 46 acres of the Great Meadows Marsh in Connecticut that was degraded from dredge material that was dumped on site, poor drainage, and sea level rise. The marsh was also overrun with invasive plants and mosquitoes. A controlled fire was started to kill the invasive reeds growing in the marsh. Then a construction crew removed invasive plants and the dumped dredge material. Lastly, channels were carefully dug for tidal flushing which will allow the marsh to keep pace with sea level rise. Soil hummocks were constructed for Salt Marsh Sparrow habitat. Now the area continues to be monitored, assessed for resiliency, and provides a field for innovative solutions to be tested in.

Impact Information:
Monitoring immediately following the restoration revealed at least 12 saltmarsh sparrows returned to their annual nesting areas near the experimental hummocks, despite the disruptive activities taking place earlier in the year. University students will survey vegetation on the hummocks and throughout the restoration area, measuring and counting individual plants to see how different species grow at different elevations and in different types of soil, and to determine if additional plantings are needed. Audubon Connecticut will manage and control invasive plant species across the restoration area for three years, periodically removing and chemically treating the ever-persistent common reed. The project team will also monitor saltwater flooding of the marsh and carve runnels (short channels), if needed, to connect more areas to saltwater.
