Interpretive Summary:

Technical Abstract: 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 methodology for autonomously controlling free-ranging animals. Directional Virtual Fencing (DVF trademark) uses programmable sensory cues administered at the proper time and in the correct location on the animal to keep animals within a Virtual Paddock (VP trademark) delineated by a Virtual Boundary (VB trademark). Using Arc GIS 9 Tracking Analyst software, the geospatial animal data were visually depicted to move within the VP as the north and south VB moved in tandem in time and space across the landscape. Being able to manage grazing pressure using DVF will provide Prescription Stocking (RxS trademark) without the challenges wire fencing places on conventional rotational stocking strategies.
