sea oats (Chasmanthium latifolium). The ancient levees and bars deposited along the old river channels, varying in size from less than an acre up to , are slightly higher with better drainage supporting stands of loblolly pine (Pinus taeda) and water oak (Quercus nigra) with understory species such as Hooker eryngo (Eryngium hookeri), and sharp-sepal penstemon (Penstemon tenuis). Bald cypress (Taxodium distichum) and water tupelo (Nyssa aquatica) grow in and near permanent or semi permanent water and the disc water-hyssop (Bacopa rotundifolia) may be found floating or growing at the water's edge. Drainage patterns are significant in shaping and maintaining these ecosystems and drainage alterations have reduced the historical size of this community. Cypress slough (aka: sweet gum - oak floodplains in part; swamp-cypress tupelo forest; slough, oxbows, and cypress-tupelo swamps): Recognized as a distinct ecosystem by some, regarded as a component found within the flats, floodplains, and baygall bogs by others, cypress sloughs with older bald cypress (Taxodium distichum) and their buttresses and protruding knees are impressive environments. Cypress sloughs occupy low laying areas in the floodplains of creeks and rivers set back from the main channels, with still or very slow moving permanent, or semi permanent, water, like secondary channels, ox-bow lakes, sloughs, and ponds. Cypress sloughs are found throughout the region but, are perhaps more extensive in the low laying south. The dominant trees are the bald cypress (Taxodium distichum) and the water tupelo (Nyssa aquatica). Water tupelo often grow in deeper water and bald cypress in shallower parts or at the periphery, although both are adapted to growing in permanently submerged areas or on dry land with sufficient moisture. Understory trees and shrubs found growing around cypress sloughs include water or Carolina ash (Fraxinus caroliniana), water elm (Planera aquatica), river birch (Betula nigra), eastern hop-hornbean (Ostrya virginiana), and buttonbush (Cephalanthus occidentalis). Plants like lizard's tail (Saururus cernuus) and burhead (Echinodorus cordifolius) can be seen growing in shallow water with cardinal flower (Lobelia cardinalis) and sensitive fern (Onoclea sensibilis) at the water's edge. Bald cypress trees typically live for 600 years or more and some are known to have lived 1,200 years. Cypress is a valuable hardwood, particularly prized for its resistance to rot and highly valued for shipbuilding, docks, and bridges. Consequently, this ancient swamp forest, once common in the region, have been greatly reduced because of logging in the nineteenth century. Trees over 100 years
