A long-term experiment at the GCE LTER revealed that rising sea levels would negatively affect tidal freshwater marshes.

Sea level rise is expected to cause salt marshes to extend upstream at the expense of freshwater wetlands, dramatically altering the intertidal landscape. Experimental salinization reduces primary production, reduces plant species diversity, decreases respiration, and leads to loss of marsh elevation.
