Distributing free-ranging animals across a landscape to facilitate proper forage utilization is universally challenging to range livestock managers. By combining Global Positioning System (GPS) technology, Geographical Information System (GIS) methodology and a practical knowledge of animal behavior we have developed a device that autonomously controls animal distribution without conventional wire fencing or herding. Directional Virtual Fencing (DVF) uses sensory cues administered at the proper time and in the correct location on the animal to keep animals within a Virtual Paddock (VP) that can move in time and space using programmable Virtual Boundaries (VB). Analyzing the resulting geospatial animal data obtained from the device using Tracking Analyst® Software, provides essential information for understanding and subsequently managing animal distribution.
