Stocking rate, and the resulting level of grass utilization (or grass weight removed) by grazing livestock, has more impact on grass productivity than any other single factor within the range manager’s control. Determining the level of utilization for a pasture is one of the most important measurements that a manager can make when monitoring grazing Management over the years. The photo guide and procedures presented in this publication are intended to make grass utilization estimates both rapid and useful. The terms “utilization,” “use,” and “degree of use” all have similar meanings.
