Three Methods of Determining Diet, Utilization, and Trampling Damage on Sheep RangesLaycock, W. A.; Buchanan, H.; Krueger, W. C. (Society for Range Management, 1972-09-01)Esophageal fistula sampling and ocular utilization estimates gave similar figures for dietary composition and for percentage utilization by sheep for most plant species in the tall-forb type. The paired-plot method gave higher utilization figures than the above methods because it estimated not only herbage eaten, but also that trampled. As a result, this method overestimated the dietary composition of species most susceptible to trampling damage; trampling accounted for one-half to two-thirds of the herbage removed by grazing.
