Managing cattle grazing distribution: It’s not as simple as it sounds At the Central Plains Experimental Range in northeastern Colorado, cattle were fitted with global positioning system (GPS) collars to track their grazing behavior and pasture use. Photo by Peggy Greb, USDA ARS -USDA ARS Grazing is an agricultural term to describe the natural behavior of cattle moving across pastures and rangelands as they consume different plants. Surprisingly, grazing cattle are selective about where and which plants they will eat, and land managers consider grazing distribution an essential factor in deciding how to manage their herds, including how to prevent overgrazing for conserving biodiversity of the land.
