. The need for stream vegetated buffers [electronic resource] : what does the science say? . Buffer zones (Ecosystem management); Water quality; Habitat (Ecology); Stream ecology; Riparian ecology. Scientific Recommendations on the Size of Stream Vegetated Buffers Needed to Protect Fisli and Aquatic Habitat. This home was built out of the floodplain—but on an erosive banl< overlooking the Shields River. In areas where streams are known to meander, building setbacks and vegetated buffers should incorporate non-floodplain areas overlooking the stream—because as valley stream channels naturally meander, these homes can become vulnerable to falling into the water Because of their size, small tributaries are very vulnerable to impacts from housing and other development: they are shallower, so removing trees and other shade-producing vegetation can result in harmful increases in temperature and increased evaporation rates; and they have less water, so it is easier for debilitating or toxic concentrations of pol- lutants to impact aquatic organisms in these streams. Additionally, many small tributaries are often dependent upon groundwater to maintain late sum- mer stream flows. If a housing development reduces or eliminates their access to this groundwater, these streams can partially or entirely dry up—a condition that is obviously stressful or lethal to fish and other stream organisms. Bank Stabilization As described above, the long-term health of streams, fish, and aquatic habitat requires main- taining natural stream processes—which includes natural erosion processes. In a healthy valley stream or river, banks erode naturally and the material is deposited elsewhere, which in turn builds banks and their associated floodplain. As a result of this natural process, the location of the stream channel changes over time. If given space, meandering streams cre- ate a pattern where outside bends of the stream are dominated by cut banks (caused by natural erosion), an
