Research at the Stroud Water Research Center has determined that forest is the best buffer for prevention of stream pollution, and these buffers should be at least 100 feet wide. Their report says, in part, “The Ecosystem benefits of wider forest buffers for streams include nitrogen pollution removal, soil sediment trapping, bank erosion prevention, improved temperature control, increased quantity of large woody debris, stream channel widening, improved channel meandering, and healthier habitat for macro invertebrates and fish. Meadows and grass buffers do not provide as many benefits.”
Forest runoff is good for fish too. Recent research in Canada shows that yellow perch grown faster in areas bordered by forest.
