Storm Protection | Flood Control

Healthy wetlands, forests, and other native plant communities slow surface water flows and absorb energy, protecting communities from extreme rainfall events, rising sea levels, and flooding.  Coastal native plant communities such as mangrove forests and coastal marshes absorb and slow the movement of hurricanes and other strong storms. The protective effect of coastal plant communities can extend far inland.
