Document Summary

Land adjacent to river, stream, or other body of water that is, at least periodically, influenced by flooding: most often bottomland hardwoods and floodplain forests , pfo and pss (not riverine, which refers specifically to the deep-water stream) Extent: wherever streams and rivers are found. Starts with perennial streams: together, riparian forests and freshwater swamps are the most extensive class of wetlands in the us. Meander scrolls: depressions or ridges within the floodplain. Point bars: sedimentation on inside of bends (where plants eventually grow) Sloughs: dead water in meander scrolls (low-lying areas in ridges) Inability to receive sediments means higher effects of erosion: this is caused by climate shifts and by dams. There are two ways of describing patterns of biota found in flowing water systems: river continuum, flood pulse concept. Headwaters: low diversity, production to respiration ratio is less than 1.
