Breaking Down Barriers with Virtual Fence

The fertile lands of the Greater Yellowstone Ecosystem support iconic wildlife and the rancher's livelihoods of countless people. 

The vast public and private lands that make up Greater Yellowstone are crisscrossed with miles upon miles of fences. While fences aren’t inherently bad—and are often necessary in certain areas to keep wildlife off roads, livestock contained, and property boundaries visible—they create barriers that fragment wildlife habitat. Virtual fence helps to solve this conservation problem by enabling livestock to be fenced off without the need for physical fencing.

This emerging technology is rapidly gaining traction across the Greater Yellowstone Ecosystem.

By enabling precise grazing, real-time livestock location tracking, and virtual herd movement, virtual fence can help livestock producers save time and reduce costs. At the same time, it offers conservation benefits by allowing wildlife to move across the land with fewer physical barriers, keeping livestock out of sensitive habitat areas, supporting rotational grazing that maintains rangeland health, and improving separation between livestock and wildlife such as elk and grizzly bears.

Most people have seen virtual fences for dogs that use collars and a buried cable to keep dogs from running off. The collars administer beeps and small electric shocks within a certain range of that cable that deter the dog from crossing the invisible boundary.

Virtual fencing for livestock works similarly. Livestock wear collars containing a battery-powered transceiver and use GPS, wireless signals, and radio frequency to “talk” to base stations. Cows receive auditory signals that scale up to electric stimuli the closer they get to a virtual boundary established by the livestock manager. The technology allows livestock managers to move their stock without having to physically move fence lines.

What is Virtual Fence?

Virtual fencing is a technology that controls livestock movement using GPS-enabled collars that emit auditory and/or electrical cues as the animals approach the boundary set by producers, eliminating the need for physical barriers like barbed wire. The collars are managed remotely via a computer or mobile app, allowing flexible and adaptable grazing management. Animals learn to avoid areas with virtual fences through classical conditioning. 

Key Benefits

  • Flexible management: Boundaries can be changed remotely and quickly to adapt to changing needs. 

  • Labor savings: Can reduce the time spent moving, building, and repairing traditional fences. 

  • Return on Investment: Can be a cheaper alternative to traditional fencing, especially on large properties. Can reduce gathering time, provide quicker location and identification of predation, potentially prevent cow/calf losses during calving, and possibly provide more effective disease transmission management with easier herd movement. 

  • Improved grazing: Can allow for management that optimizes forage utilization and rotational grazing without physical barriers. 

  • Conservation: Can protect sensitive areas, improve soil health and vegetation productivity, bunch cattle for predator conflict mitigation, allow for mimicking wildlife grazing patterns, and remove physical barriers that harm wildlife. 

Potential Limitations

  • Signal and coverage issues: Virtual fences rely on GPS, cellular, and LoRa radio communication signals, which can be unreliable in areas with dense tree cover, steep slopes, or poor cellular service. 

  • High initial cost: There can be a significant upfront cost for the collars and necessary base stations or towers. 

  • Learning curve: There is a learning curve for producers to implement and manage the technology effectively. 

  • Not a “Set-It-and-Forget-It” System: Virtual fencing is a dynamic management tool that requires ongoing attention for tracking battery status, updating boundaries, and monitoring animal behavior and training. 

  • Does not eliminate the need for some existing fence: Boundary fences and fences in high-risk areas, such as along highways, are still needed. 

While virtual fences have proven benefits for livestock producers and conservation, it should not be considered a magic bullet. Rather, it is another tool in the toolbox for livestock management. Technology is constantly evolving and improving, and if it isn’t right for your operation now, it could be in the future. Each product is slightly different and doing your homework can save you a lot of headaches in the future.

The conservation and livestock management benefits that virtual fence technology may have are further explored in “Advancing Conservation Through Virtual Livestock Fencing,” an article co-authored by GYC that was recently published in the Biological Conservation journal. The article was led by Drew Bennett, Whitney MacMillan Professor of Practice in UW's Haub School of Environment and Natural Resources, and co-authored by Haub School colleagues Temple Stoellinger and Jacob Hochard, and UW Zoology and Physiology faculty Jerod Merkle and Kurt Smith, along with collaborators at the Property and Environment Research Center, UC Berkeley, World Wildlife Fund, and the Wyoming Wildlife Federation.
