Riparian forest buffers in agroecosystems — lessons learned from the Bear Creek Watershed, central Il-season grasses may provide better function for riparian forest buffers in specific settings. Properly designed riparian buffers have been shown to effectively reduce surface NPS pollutant movement to streams and under the right geological riparian setting can also remove them from the groundwater.

Short-rotation woody crops and phytoremediation: Opportunities for agroforestry?for phytoremediation success. Among the different agroforestry practices, riparian buffers have the greatest opportunity for realizing the SRWC and phytoremediation potentials of fast growing trees. Agroforestry that combines SRWC and phytoremediation could be an emerging holistic approach for susta

Forest gardens as an ‘intermediate’ land-use system in the nature-culture continuum: Characteristicsa long period of time as a result of local community’s creativity, forest gardens have still received little attention in agroforestry research, just as in the case of the more intensively domesticated homegardens. The study of forest gardens offers good opportunities for obtaining a better understa
