Optimizing Buffer Placement and Effectiveness

Posted on February 14th, 2018

In a research paper recently published in Landscape Ecology, by Keith Schilling (Associate State Geologist), Peter Jacobson (Grinnell College) and Calvin Wolter (Iowa DNR), the authors evaluated the patterns of sediments, water quality and land use in southern Iowa riparian zones.  Riparian zones are the strip of land which borders streams, usually classified in zones within 35 to 180 feet from the channel.

This evaluation allowed the authors to make recommendations for the placement of riparian buffers in this region.  Riparian buffers, consisting of grass and forest, filter water and nutrients running off from adjacent agricultural land.
