Livestock managers are looking for information on several factors affecting grazing distribution before implementing land management strategies. With this in mind, researchers at USDA-ARS completed a cross-site collaboration study with university-operated experiment stations and four LTAR funded sites, with the primary goal of determining how factors like landscape topography and water availability affect cattle grazing distribution. The data collected at all sites creates a benchmark for understanding how environment can drive the spatial patterns of animal use in pastures under several management practices and across the various ecosystems. The study collected data from seven rangeland sites in Florida, Nebraska, New Mexico, Colorado, and Idaho and used collars equipped with global positioning system (GPS) technology to measure cattle movement and activity. This technology was successfully used in prior studies completed by scientists David J. Augustine and Justin D. Derner, from the Rangeland Resources and Systems Research Unit, at Fort Collins, CO and Cheyenne, WY.
