Kenilworth Marsh Tidal Wetland Restoration, Washington D.C.

The Kenilworth Marsh tidal wetland restoration project, led by the National Park Service, aimed to restore areas in Washington, D.C. that were degraded from altered hydrology and contamination. The project team placed 130,000 cubic yards of dredged material to restore hydraulic function of the tidal marshes, installed over 350,000 native plants, and removed invasive purple loosestrife and phragmites. The dredging and recontouring of the site reconnected the natural hydrology of the site, and over 90% of revegetation area were covered with dense plant growth in the first year. The restoration also led to the recolonization of the site by new wildlife, particularly bird species.
