Salt marshes are salty due to their proximity to coastal areas where saltwater from the ocean mixes with freshwater from rivers and streams. The tidal influence brings in seawater, which evaporates and leaves behind salt, while the vegetation and soil also contribute to the saline environment. Additionally, the lack of significant freshwater flushing can lead to increased salinity levels in these ecosystems. This unique salinity supports specialized plant species adapted to thrive in such conditions.
