permanently or temporarily wet areas of land or shallow water, with fluctuating land-water margins, that support plants and animals specially adapted to wet conditions. People generally think of wetlands as areas of waterlogged ground and shallow waters with emergent vegetation, such as are often found at land-water margins, and describe these as bogs or swamps. Technically, however, the term ‘wetland’ can also include shallow lakes and ponds, tidal estuaries, and lagoons, as well as bogs (fed by rainwater alone) and swamps (fed by streams, groundwater or run-off).
