Many in the range profession are perplexed by the apparent discrepancy between experimental studies suggesting that rotational grazing carries no advantage over continuous grazing1 and the observations of ranchers and range mana gers who have personally seen benefi ts for livestock pro duction and plant communities by shifting to a rotational system.2,3 We believe one reason for this seeming contradiction is that research on plant and animal production is typically designed to control for the effects of behavior of grazing animals and their owners. As researchers who have spent many years studying the behavior of range livestock and people, we argue that understanding human and animal behavior as it relates to grazing management can help to bridge the gap between science and practice. In this paper we discuss how livestock behavior factors (such as prior experience and stress) and managers’ learning processes can infl uence the outcomes of grazing management practices, why a standard experimental approach may not detect those infl uences, and how an improved knowledge of behavior can help both ranchers and researchers achieve their goals with respect to rotational grazing systems. |
