Weeks, months, or y� �y'intervene between periods of <br /> , inundation. The dominant plant communities may change as soil moisture conditions change. <br /> According to Cowardin et al (1979, pg 22) "Some areas exhi'biting this regnne do not fall within <br /> ow defnition of wetland because they do not have hydric soils or support hydrophytes." Some of <br /> , the areas in agricultural fields tliat have been flooded durnig the spring and early sumrr�er of <br /> 2003 and 2004, following periods of intense and persistent rainfall, may well fall into this <br /> category and may not in fact be subject to regulation as a wetland. <br /> ' « » <br /> Modifier K <br /> , ArtiHciaIly Flooded(ArtlHcial) <br /> The amount and duration of flooding is controlled by means of pumps or siphons in combination <br /> with d�kes or dams.
