Coastal, or saltwater, wetlands consist of salt marshes and mangrove swamps. These habitats fuel both terrestrial and aquatic food chains. Wetlands contribute to water quality by removing excess nutrients and pollutants that originated in the uplands before they reach the estuary. Wetlands also offer important habitat for a wide variety of organisms that rely on the area as a nursery ground, and provide protection against coastal erosion.

A Class I permit is required prior to doing any work in, on, over, or upon the tidal waters of Miami-Dade County or any of its incorporated municipalities.
