A Wetlands Definition
The federal regulations implementing Section 404 of the Clean Water Act define wetlands as:
-- Those areas that are inundated or saturated by surface or ground water (hydrology) at a frequency and duration sufficient to support, and that under normal circumstances do support, a prevalence of vegetation (hydrophytes) typically adapted for life in saturated soil conditions(hydric soils). Wetlands generally include swamps, marshes, bogs, and similar areas (40 CFR 232.2(r)).




Wetlands Vegetation Characteristics
Vegetation - Hydrophytic
Obligate - Nearly always found in wetlands, i.e. cattails, swamp azaleas, white cedar
Facultative Wetlands - Occur in wetlands 2/3 of the time, i.e. pin oaks, elderberry
Facultative - 1/3 to 2/3 of the time, but also in uplands, i.e. red maples, witch hazels
Uplands - more likely in uplands, in wetlands less than 1/3 of the time, i.e. Beech, American Holly


Wetlands Soil Characteristics
Soils - Hydric
Organic - High percentage by volume of organic material because decomposition is slowed by a lack of oxygen
Mineral - Low percentage organic material, become hydric when saturated long enough to change properties

Wetlands Hydrology Characteristics
Hydrology
4 Sources of water
direct precipitation
runoff from adjacent lands including inflow of streams
groundwater inflow
ocean tide water
4 ways to lose water
evapotranspiration
seepage into the ground
stream discharge
tidal outflow
