Design and Plant Your Buffer
100 feet of streamside forest will adequately protect the physical, chemical, and biological characteristics of most streams. However, narrower buffers are also beneficial for improving water quality.
Many landowners are happy growing a forest next to their stream for clean water and habitat. But with extra planning, landowners could harvest products from their forest buffer. These multi-functional buffers may not be eligible for some of the federal programs that have been outlined under the Funding section, but they may appeal to landowners for other reasons.
Ideally, the buffer along a stream whether urban or rural, should be contiguous. Achieving such uniformity can be even more challenging in developed areas, and there is the additional challenge of potentially heavy use by people. A typical stream in a developed area goes through a city or residential area where there may be only narrow bands of land available for planting. Any buffer width is beneficial, but buffers that are at least 35 feet wide provide better water quality improvement.
