If all parts of a range are to be grazed for production and ungrazed for improvement over a period of years, there must be some sort of planned grazing rotation. Actual benefits from rotations have varied, and objectives have not always been attained. Few studies and experiments have quantified the chain of events from deteriorated conditions to higher range condition and increased profits; yet considerable experience has established that scheduled rotational grazing benefits the range and can be profitable, when livestock travel distance is decreased and uniformity of forage utilization is increased.
