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.

Contact: Wyoming Sales Rep – Emery Fine, emery.fine@halter.co.nz, (307) 206-2350
Company Statement: Halter collars use sound and vibrations to contain and move your herds across the range. A low-energy electric pulse, significantly weaker than an electric fence, is used only when cows repeatedly ignore the primary cues, keeping animal welfare our top priority.
Collars: Collars are fully owned by the customer but are on a subscription basis, meaning they do not purchase the collars; they are included with subscription. The annual subscription for Halter is $72/year per collar, with a lifetime warranty.
Batteries: Halter collars are solar charged, eliminating the need to change batteries.
Base Stations/Towers: Towers are $4,500 each. A Halter specialist will work with you to determine the number of towers appropriate for your operation.

Contact: sales.us@nofence.no
Company Statement: The Nofence system works best with good-to-excellent cell coverage. While Nofence collars function exclusively on AT&T and T-Mobile networks, the app can be used on any mobile device with any cell service. If you have AT&T or T-Mobile, simply check your signal strength in the pasture—three or more bars is ideal. If you use a different carrier, confirm your pasture has network coverage using these AT&T and T-Mobile coverage maps.
Collars: Collars are fully owned by the customer. Cattle collars are $345/each for 5-49 collars or $331/each for orders of 50 or more, with the first year's subscription included. Sheep and goat collars are $255/each for 5-49 collars or $241/each for orders of 50 or more, with the first year's subscription included.
After the first year, all collars are automatically enrolled in a subscription with ongoing monthly or yearly costs based on the number of collars in use and whether they are used all year or for a select number of months. All collars have a 5-year warranty
Batteries: Nofence collars use built-in solar panels to extend the life of their rechargeable batteries, which typically last 6-9 months. Battery life may vary depending on grazing intensity, pasture size, sunlight, and cell coverage. You can easily check battery levels in our app and swap them out — no tools needed. For best performance, we recommend pastures of at least half an acre with good sun exposure.
Base Stations/Towers: N/A; GPS & cell service only

Contact: Allison Burenheide, allison.burenheide@merck.com or Cuinn Merrigan, Senior Territory Manager, cuinn.merrigan@merck.com
Company Statement: Vence is built for hard to fence, extensive areas. Our base stations cover 7,500+ acres depending on topography, and we have had huge success/great efficacy in places with little to no cellular service because our collars run on Lora WAN to check in with the base station, not needing cellular service to talk to the base station. We have a fantastic Rancher Success Team who are there for onboarding ranchers, training cattle, and any needs for their Vence use.
Collars: Collars are leased at $50/cow for an annual subscription, which includes the battery.
Batteries: Extra batteries are $10/battery.
Base Station/Towers: Base stations are $10k for self-install, $12k for the Vence team to install it.

Contact: Alexis Bonogofsky, Director Sustainable Ranching Program, alexis.bonogofsky@wwfus.org
Funding Opportunity: World Wildlife Fund’s (WWF) Sustainable Ranching Initiative (SRI) is partnering with ranchers across the Northern Great Plains (NGP) to increase sustainable grassland management on one million acres in five years. Through the Ranch Systems and Viability Planning network (RSVP), WWF has established a comprehensive support system for ranchers to develop sustainable grazing management plans with assistance from on-the-ground technical specialists and to access continuing education to improve ecological outcomes at scale in the NGP.
Landowners in the RSVP program can apply for funding in the form of cost-share for ranch improvements. This is intended to encourage increased adoption of sustainable grazing practices in the NGP. Project costs are expected to be shared with the rancher and/or additional contributing partners, if applicable. Currently, the standard for cost-share projects is that WWF will pay up to 50% of the balance of the total project cost not covered by the rancher and or contributing partner, with a maximum of $60,000 per ranch.
