Virtual Fencing: A New Tool for Livestock and Land Management 

Virtual fencing (VF) is a precision agriculture tool gaining traction across California’s diverse rangelands. It uses GPS collars to contain livestock without physical fences. Producers set virtual boundaries across their pasture from a computer, which are transmitted to the collars. When an animal approaches the boundary, the collar emits audio cues and, if needed, mild electric pulses to keep the animal within the boundary.

While not a replacement for a secure perimeter fence, VF can help position animals across a landscape with more intention and precision than traditional fencing. VF can be adjusted in minutes to meet the changing needs of livestock producers and range conservationists alike. 

Applications include:

• Targeted grazing to control invasive weeds
• Installing fuel breaks to reduce wildfire risk
• Automated rotational grazing
• Excluding livestock from sensitive areas
• Real-time livestock location tracking
 

With NRCS funding, the UC Cooperative Extension Central Sierra is researching VF applications on California rangelands.
