The marsh at Seatuck NWR has been degraded since at least the 1930s. Impairments included mosquito grid ditching in the 1930s, subsequent road construction, the disposal of dredge material from an adjacent tidal creek and harbor, and shore line erosion and advancement. By 2012, when Hurricane Sandy made landfall in the area, large portions of the marsh were deprived of sediments and had become waterlogged. Mr. Shotzberger led AKRF’s design team to widen existing channels, fill legacy grid ditches and waterlogged marsh plain with old dredge material, create new sinuous channels within the marsh, and apply herbicide to invasive Phragmites. Construction efforts were completed in 2017, and by 2018, native marsh vegetation had begun to recolonize the marsh plain.
