Just when you thought you'd heard everything about virtual fence, another podcast episode comes along. But Dr. Flavie Audoin, University of Arizona Cooperative Extension rangeland specialist, may be one of the most importance "voices" to listen to on the strengths and weaknesses of virtual fence and animal geolocation technologies. She has been in the middle of much of the early vendor comparison work as well as experimental research on animal physiology considerations and environmental applications for remote animal location detection and control. Listen to this interview to learn about the mechanisms of virtual fence options, a comparison and contrast of features on offer, and current research on graziers can better manage wild, open spaces with a back-to-the-future approach to modern herding. The Art of Range Podcast is supported by the Western Extension Risk Management Education Center, Vence (a subsidiary of Merck), and the Idaho Rangeland Resources Commission. Music by Lewis Roise.
