Appropriate buffer
design will depend on many local factors including climate, soils,
hydrology, and farming practices. Buffer species need to be adapted
to the region and appropriate for other functions such as wildlife
habitat. Climate can greatly affect buffer function. For example,
winter rains on frozen soil in northern areas produce runoff which
cannot be processed by buffers. Rainfed agriculture produces different
runoff patterns than agriculture dominated by irrigation. For these
reasons, it is essential that those planning installation of buffers
get local input to benefit from local experience and research. In
addition, specific buffer design specifications are often required
to qualify for cost sharing programs.
Local NRCS offices
can provide design specifications for your area. In addition, Extension
is also a source of expertise and information. Many State Extension
Services have developed publications on buffer design and maintenance.
