Besides, salt marshes and mangroves play an important role in keeping coastlines stable and could considerably reduce coastal infrastructure costs, which might make restoration engineering and sustainable management of marine ecosystems more economical ( Hochard et al., 2019; van Zelst et al., 2021 ). To provide these leaders with as many options as possible, Bell is also talking with state and federal agencies to encourage inclusion of NBS in their work as well. Most of the harvested species depend on the salt marsh-tidal creek ecosystem as a nursery and refuge from predators. The U.S. Breaching the sea defences at Tollesbury in 1995. They are found in the intertidal zones along low-energy coastlines, forming along the margins of estuaries, where freshwater from the land mixes with seawater. Increasingly sophisticated numerical models have also been developed to visualize flow patterns and calculate groundwater exchange. TNC is collaborating with partners to ensure that pure drinking water for one in six Mainers stays that way. Phragmites provides many benefits that are generally unknown and unappreciated. When the marsh platform is gradually exposed during falling tides, groundwater seeps out from the marsh sediments into tidal creeks. Its a good example of what we call a nature-based solution or NBS, says Bell. Salt marshes in other nations have also suffered great losses. The entire area is flooded by seawater at high tide and drained at low tide. Innovative options are already being considered on both U.S. coasts. In addition, salt marshes provide many benefits including cleaner water and air.
