					| Bottomland hardwood forests are river swamps where the water 
					table remains elevated during the winter and spring seasons 
					and soils remain moist through much of the growing season. 
					They are found along rivers and streams of the southeast and 
					south central United States, generally in broad floodplains. 
					Bottomland hardwood forests receive periodic inundation from 
					rivers during heavy rainfall events. Periods of flooding can 
					last for several days to a month or more. Tree species like 
					bald cypress, tupelo, black gum, and some oaks have the 
					ability to survive seasonal flooding and are found in 
					bottomlands. Often, the key identifying features of these 
					wetland systems are the fluted or flaring trunks that 
					develop in several species, and the presence of knees, or 
					aerial roots. Click
