Wetland functions and ecosystem benefits. 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. Since wetlands may provide food and habitat for many terrestrial and many aquatic species, wetland biodiversity is often higher than that of adjacent ecosystems.
Wetland conservation is aimed at protecting and preserving areas where water exists at or near the Earth's surface, such as swamps, marshes and bogs.Wetlands cover at least six per cent of the Earth and have become a focal issue for conservation due to the ecosystem services they provide.etlands generally include swamps, marshes, bogs and similar areas.. Wetlands vary widely in their salinity levels, climatic zones, supported flora, surrounding geography, whether they are coastal or inland and so on.
