As sea levels rise, wetlands are encountering physical barriers to inland migration — a phenomenon known as “coastal squeeze.” Wetlands are being squeezed between sea-level rise on one side and human development on the other, preventing their natural ability to adapt by moving inland to higher ground. To respond to these threats, there are two primary management responses state and local governments may consider: (1) maintaining existing or restoring coastal wetlands; and (2) facilitating their migration inland (Georgetown Climate Center).
