What are the five major wetlands?

What is the function of wetlands?
Wetland functions are defined as the physical, chemical, and biological processes or attributes that are vital to the integrity of the wetland system. Because wetlands are often transition zones (ecotones) between terrestrial and deepwater aquatic systems, many processes have major implications for species.
What are the laws of wetlands?
The Wetlands Protection Program. The law protects not only wetlands, but other resource areas, such as land subject to flooding (100-year floodplains), the riverfront area (added by the Rivers Protection Act), and land under water bodies, waterways, salt ponds, fish runs, and the ocean.
