The most recent definition of wetlands is given by Lugo (1990, p. 2): “Wetlands are areas that are inundated or saturated by surface water or groundwater, at such a frequency and duration that under natural conditions they support organisms adapted to poorly aerated and/or saturated soil.” This definition uses the following criteria: saturated or poorly aerated soil, and biotic response to the soil condition. According to the Canadian definition (Zoltai and Pollett 1983), wetlands are areas where wet soils are prevalent, having a water table near or above the soil surface for most of the thawed season, supporting hydrophilic vegetation, and they include pools of open water (less than 2 m deep). This means that shallow open water is also included in wetlands (Zoltai and Pollett 1983).
