First-year results are now available in a long-term study of the popular short-duration grazing system, also known as controlled or intensive grazing, under way at the UC Sierra Foothill Range Field Station. The 1988 experiment compared two grazing intensities in an eight-paddock rotation with 3-day grazing and 21-day forage regrowth intervals. A stocking rate predictor was developed based on plant height, and a close relationship was found between heifer weight gains per acre and amount of forage removed.

Appreciation is expressed to Donald L. Springsteen and other members of the support staff at the station, and to undergraduate students (UC Davis) Jennie Mohler and Paul Wallace for valuable assistance.
