science and policy research headwaters protection: trout stream buffer study This study was commissioned by the Georgia Environmental Protection Division in response to amendments made to Georgia's Erosion and Sedimentation Act by the General Assembly during the 2000 legislative session. Among other changes, the amendments reduced the minimum riparian forest buffer width on trout streams from 100 ft to 50 ft. Implications of Changes in Riparian Buffer Protection for Georgia's Trout Streams, Judy L. Meyer, Krista L. Jones, Geoffrey C. Poole, C. Rhett Jackson, James E. Kundell, B. Lane Rivenbark, Elizabeth L. Kramer, William Bumback, October 2005. Relationships between trout populations, stream habitat, and average forested riparian buffer widths were used to evaluate the potential for North Georgia’s streams to maintain high quality trout habitat given different riparian buffer widths. Findings include that, on average, in a stream where the forested riparian buffers were reduced from 100 ft to 50 ft along the length of the stream, the biomass of young trout would be reduced by over 80% due to associated stream warming and increased amounts of fine sediments.
