' <br /> � of the growing season but is waterlogged to within at least a few inches of its surface. Vegetation <br /> includes grasses,rushes, sedges, and various broad-leaved plants. In northern environments,typical <br /> ' species representatives are carex, rushes, redtop, reedgrasses, mannagrasses, prairie cordgrass and <br /> mints. Meadows may be present in shallow lake basins, sloughs, farmland "sags" or may border <br /> � shallow marshes on the landward side. <br /> Table 4(Cowardin et al p. 28)includes within�ts description of Type 2 wetlands as fen and northern <br /> � sedge meadow. The water regime is described as saturated (B). This description, as used by some <br /> plant ecologists and wetland scientists,is specifically limiting and at least in some instances does not <br /> suggest that reed canary grass dominated wetlands would fall into this category. <br /> ' Type 3 —Inland Shallow Fresh Marshes <br /> Inland shallow fresh marshes (Type 3) wetlands have a soil substrate that is usually waterlogged <br /> ' during the growing season and at some times may be covered with as much as 6 inches or more of <br /> water. Common vegetation includes grasses,bulrushes, spikerushes, and various other marsh plants <br /> such as cattails, arrowheads,pickerelweed, and smartweeds. Common representatives in the North <br /> � include reed, whitetop,rice cutgrass,carex and giant burreed.Type 3 marshes may nearly till shallow <br /> lake basins or sloughs or may border deep marshes on the landward side. They may also occur as <br /> seep areas in agricultural fields resulting from failing drain tile systems or where sand seams are near <br /> � the sur�ace on hillside slopes. <br /> Cowardin et al (Table 4, pg 28) describes the water regime as either seasonally flooded (C j or <br /> � semipermanently flooded(F). The accurate categorization of Type 3 wetlands is most critical since <br /> seasonally flooded wetlands containing reed canary grass are eligible for larger de minimus fills (up <br /> � to 10,000 square feet) than cattail marshes (only 400 square feet). The difference in hydrological <br /> regimes is discussed in the next section. <br /> ' Type 7—Wooded Swamps <br /> Wooded swamps (Type 7)wetlands have a soil substrate that is"waterlogged to within a few inches <br /> of its surface" (Shaw and Fredine 1956, pg 22)during the growing season and often can be covered <br /> ' with as much as 1 foot of water.Type 7 wetlands often occur along the edges of sluggish streams,on <br /> floodplains, on flat uplands and in very shallow lake basins. In the North, trees include tamarack, <br /> arbor vitae, black spruce,balsam, red maple, and black ash. Northern evergreen swamps frequently <br /> , have a thick ground cover of mosses. Deciduous swamps frequently contain beds of duckweeds, <br /> smartweeds and other herbaceous plant species. Hardwood swamps frequently are associated with <br /> Type 6, shrub swamp wetlands. <br /> � Table 4 (Cowardin et al 1979, pg 28) states that Type 7 wetlands include all water regimes except <br /> permanently flooded.This description is inconsistent with the more specific description of Shaw and <br /> � Fredine(1956)that describes a Type 7 wetland as having waterlogged soil to within a few inches of <br /> the surface throughout the growing season. <br /> � Wooded swamps (Type 7) are frequently mischaracterized as bottomland hardwoods (Type 1 Lj, <br /> � Svoboda Ecological Resources 744 Brown Road North <br /> Project No.: 2007-081-03 33 Ted Sehultze <br /> � <br />
