A: Temporarily Flooded - Surface water present for brief periods during the growing season,but <br /> the water table usually lies well below the soil surface. Plants that grow both in uplands and <br /> wetlands are characteristic of this water regime. The temporarily flooded regime also includes <br /> wetlands where water is present for variable periods without detectable seasonal periodicity. Weeks, <br /> months, or even years may intervene between periods of inundation. The dominant plant <br /> communities under this regime may change as soil moisture conditions change. � <br /> B: Saturated -The substrate is saturated to the surface for extended periods during the growing <br /> season,but surface water is seldom present. � <br /> C: Seasonally Flooded - Surface water is present for extended periods especially early in the <br /> ' growing season,but is absent by the end of the growing season in most years. When surface water is <br /> absent,the water table is often near the land-surface. The water table after flooding ceases is highly <br /> variable, extending from saturated to a water table well below the ground surface. <br /> F: Semipermanently Flooded -Surface water persists throughout the growing season in most years. <br /> When surface water is absent, the water table is usually at or very near the land surface. , <br /> G: Intermittently Exposed - Surface water is present throughout the year except in years of <br /> extreme drought. - <br /> H: Permanently Flooded -Water covers �he land surface throughout the year in all years. � <br /> Vegetation is composed of obligate hydrophytes. <br /> 4.1.4.5 Special Modifiers <br /> Many wetlands and deepwater habitats are man-made and natural ones have been modified to some <br /> degree by the activities of man or beavers. Since the nature of these modifications often greatly <br /> influences the character of such habitats, special modifying terms have been included here to <br /> emphasize their importance (Cowardin, et al., 1979). <br /> b: Beaver—Created or modi�ed by a beaver dam. <br /> d: Partly Drained—The water level has been artificially lowered,but he area is still classified as <br /> wetland because soil moisture is sufficient to support hydrophytes. Drained areas are not considered <br /> wetland if they can no longer support hydrophytes. <br /> 1\fred\wp�23�27�D06�Reports�Fina1 Report\Wetland mgmt�lan_dft011503.doc 4-9 <br />
