Long-term Effects of Grazing Management and Buffer Strips on Soil Erosion from Pastures.

abstract：:This study examined the effects of agricultural runoff on the vegetation structure of Franklin Bog, a priority conservation area located in a rapidly developing region of northwestern Vermont. Forested and agricultural runoff from the mixed land use watershed created differential vegetation patterns in the wetland, in...
