Which consequence results when coastal dunes migrate inland onto wetlands?

💡 Explanation

Inland dune migration overtops and smothers coastal wetland sedge peat. This causes increased saltwater intrusion through displacement via groundwater mixing, known as hydraulic conductivity, because the dune sand's increased porosity allows greater water movement, therefore salinizing the wetlands, rather than altering carbon or nutrient cycling.
