Wetland – “those areas that are inundated or saturated by surface or groundwater at a frequency and duration sufficient to support, and that under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions. Wetlands generally include swamps, marshes, bogs and similar areas.” --- EPA Clean Water Act enforcement definition
Wetlands Emergent macrophytes (vegetation)
effectively define wetlands.
Marsh = dominated by non-woody vegetation.
Swamp = dominated by trees. Aquatic Marginal Wetlands = emergent
macrophytes can grow around a body of surface water (lake, stream, ocean). – presence depends on substrate and water conditions (Can emergent macrophytes grow there?)
-Fringe wetlands – almost always wet
-Flood wetlands – seasonally or less frequently wet
Wetlands Mires = where emergent macrophytes can
grow BUT are not around an open body of water and are permanently waterlogged. –depend on groundwater and/or reliable runoff
-Fens – “fed” by groundwater and runoff; nutrient rich
-Bogs – “fed” runoff (above the water table); nutrient poor; mosses of the genus Sphagnum.
