does not fit the Type 7 Hardwood Swamp wetland type. Table 4 (Cowardin et al 1979, pg <br /> 28) is inconsistent by including this regime in the Type 7 category. <br /> Modifier "B" <br /> Saturated <br /> Soil saturation occurs to the surface for extended periods during the growing season but <br /> surface water is seldom present or evident. Many sedge and rush wetlands fit into this <br /> category. This modifier also aptly fits the water regime that occurs in the hardwood <br /> swamps that are present in parts of Minnesota in hardwood swamps such as black ash <br /> swamps and in coniferous swamps such as white cedar, tamarack, and black spruce <br /> swamps. This modifier also describes Type 2 wetlands as described above and includes <br /> fens and sedge/rush dominated wetlands. <br /> ModiFer"C" <br /> Seasonallv Flooded (Seasonal) <br /> Surface water is present for extended periods especially early in the growing season but is <br /> absent by the end of the season in most years. When surface water is absent, the water <br /> table is often near the surface. Santos and Gauster (1993, pg 31) add that the water table, <br /> after flooding ceases, is very variable, extending from saturated to a water table well <br /> below the surface. This accurately describes the situation that frequently occurs within <br /> reed canary grass wetlands where there is saturation to the surface or even several inches <br /> of inundation after snow melt. In most years, by the end of May, surface water is no <br /> longer evident in many of these basins. During June, the water table continues to recede <br /> until by August, the water table may be two or more feet below the surface. Many of <br /> these areas are used for livestock pasturing and for harvesting meadow hay. Wetlands <br /> with a "C" modifier that consist predominantly of reed canary grass should be <br /> categorized as either Type 1 or Type 2 depending on the length of time that water is <br /> present. This modifier is the most difficult to specifically assign to a Type 1, Type 2 or <br /> Type 3 category as it could apply to any of the three. <br /> Modifier "D" <br /> Seasonal Well-Drained (No comparable Cowardin cate�orv) <br /> Santos and Gauster(1993, pg 31) describe this modifier as applying where surface water <br /> is present for extended periods especially early in the growing season. The water table, <br /> after flooding ceases falls well below the ground surface. This modifier would appear to <br /> apply to floodplains and bottomland hardwood forests (Type 1L) as described above. <br /> Modifiers "C" and "D" seem to overlap to a certain extent and could also apply to reed <br /> canary grass wetlands as well. <br /> Modifier "E" <br /> Seasonal Saturated (No comparable Cowardin cate�orv) <br /> Surface water is present for extended periods especially early in the growing season, and <br /> remains saturated near the surface for most of the growing season (Santos and Gauster <br /> 1993, pg 31). This modifier would appear to apply to fens, sedge and rush meadows, <br /> some Type 6 shrub swamps, Type 7 Hardwood Swamps and Type 8 bogs. Some reed <br />
