wetlandszones
Wetlandszones refer to geographically defined areas in which the soil is saturated with water for at least part of the year and where the biological community is adapted to aquatic or semi-aquatic conditions. These zones include freshwater wetlands such as marshes, swamps, and bogs, as well as tidal and coastal wetlands such as mangroves and salt marshes, and inland unimproved wetlands. The defining features are hydrology, soil type, and vegetation; the hydroperiod, soil moisture, and depth of the water table shape the ecosystem.
Wetlandszones provide a range of ecosystem services: they store floodwaters, attenuate storm surges, filter pollutants, cycle
Threats include drainage for agriculture and development, water pollution, invasive species, altered hydrology, and climate change.
