Interpretive Summary: The potential for beef cattle to impact the vegetation, channel morphology, aquatic habitats, and water quality of rangeland riparian areas is an important and controversial issue in the western U.S. and similar regions throughout the world. Although cattle use of riparian area has been extensively studied, the fine-scale spatio-temporal behavior of cattle in riparian pastures has received little research. We are employing high temporal-resolution (1-sec sampling intervals) GPS tracking collars on beef cattle to examine their fine-scale distribution patterns in different 3 managed riparian grazing systems over 2 years. Preliminary findings indicate these GPS data will allow us to accurate quantify cattle movement velocities and classify cattle behavior based on these velocity values.
Technical Abstract: The objective of this research is to study cattle site use and behavior in riparian pastures so that the nature of use by livestock can be determined and potential ecosystem impacts can be scientifically evaluated. Through the course of this study, we will employ high resolution GPS trackers to examine the fine scale distribution of livestock on 3 managed riparian grazing systems over 2 years. Patterns of land use in relation to stream channel, stream banks and vegetative communities are being documented as well as use of and preference for ecological sites.
