I found this article of information on how to begin grazing. I thought that it was interesting. It starts with some information that will aid in setting economic goals for the graziers. It reports some studies that have been done to prove the economic advantages to grazing. For example, grazing animals can manage vegetaion on the banks of rivers resulting in increases fish populations and also prevent fish overpopulation. It concludes by suggesting ways to select the species to graze.
