David M. Vetrano worked as a fisheries biologist for the Wisconsin Department of Natural Resources for more than 33 years. Almost all of his time was spent managing the cold-water program in streams of the Driftless area in Southwest Wisconsin. While there, he witnessed the streams change from “put and take”, heavily stocked waters to self–sustaining streams with very little stocking. During his tenure he realized managed grazing had the potential to rebuild the rural landscape while protecting water quality.
