The main types of intertidal wetlands are mudflats (e.g., mangrove swamps) and salt marshes. The mangrove swamps are encountered along tropical shores and are characterized by tree vegetation, while salt marshes are mostly found in temperate zones and are mostly grass ecosystems.

The Wetlands Geodatabase and the Wetlands Mapper, as an Internet discovery portal, provide technological tools that allow the integration of large relational databases with spatial information and map-like displays. The information is made available to an array of federal, state, tribal, and local governments and the public.
An inland salt marsh is a saltwater marsh located away from the coast. It is formed and maintained in areas when evapotranspiration exceeds precipitation and/or when sodium- and chloride-laden groundwater is released from natural brine aquifers. Its vegetation is dominated by halophytic plant communities. [1]
