Virtual Fencing

How it works

How virtual fencing works:

  • Cattle are equipped with a GPS collar that emits a sound when the livestock approaches a virtual boundary, then a light shock if the animal crosses the boundary, which continues for several yards, effectively deterring cattle from entering the areas that the rancher has fenced off. Cattle need only a few days to learn that the sound from the collars means it is time to turn around.
  • Solar-powered signal towers connect across the virtual network. Each solar-powered tower covers roughly 10,000 acres of range, depending on topography, and can cost up to $12,000.
  • An app tracks the cattle’s location and sends alerts if the cattle attempt to leave the virtual fence boundary. The rancher can also adjust the boundaries directly from the app.

Benefits for ranchers:

Virtual fencing significantly reduces the need for traditional barbed-wire fences, bringing notable benefits:

  • The virtual system allows for easily customizable boundaries.
  • Ranchers can more easily track the location and status of their cattle, helping with predator control and herd management.
  • Reduce the need for bared-wire fences, which require costly and time-intensive repairs, can save ranchers considerable time and money.

Benefits for conservation:

Traditional barbed wire presents a challenge for wildlife, whose migration depends on unobstructed and expansive landscapes.

  • Open migration: Migrating wildlife can become fatally entangled with traditional fencing. Fences also serve as barriers that prevent wildlife from accessing habitat and reduce their winter range. Removing this barrier makes migration easier and safer.
  • Ecological sensitivity: Virtual fencing can also make invasive species management easier by enabling ranchers to easily “fence off” areas where invasive species need to be treated or keep animals out of areas with noxious weeds like tall larkspur, which can be fatal to livestock.
  • Habitat restoration: It can facilitate landscape restoration by protecting sensitive ecosystems such as wetlands, riverbanks, and streams.

Pilot Projects

Virtual Fence Conservation Fund

PERC’s first Virtual Fence Conservation Fund has awarded over $400,000 to pioneering farms and ranches that demonstrate the transformative potential of virtual fencing technology in livestock management and wildlife conservation.

Meet the Grant Recipients

Wolf Conflict Management

Krebs Ranch, Oregon—This project explores innovative approaches to reducing livestock-wolf interactions by using virtual fencing paired with other innovative livestock management tools to strategically manage cattle.

Partners: PERC, Colorado State University

Riparian Corridors and Big Game Migration

E Spear Ranch, Wyoming—Located in the Wood River drainage and a critical migration corridor for the iconic Cody Elk Herd, this 65,000-acre project addresses riparian corridor concerns, wildlife movement, and predator interactions while protecting historic sites, including Amelia Earhart’s cabin.

Partners: PERC, Natural Resources Conservation Service

Pollinator Conservation

B’Haven Goats, Wisconsin—This project represents the first known virtual fence initiative designed to conserve pollinator habitat, carefully managing a population of goats across 80 acres to support butterflies and nesting bobolink birds.

Partners: PERC

Riparian Restoration

Badger Creek Ranch, Colorado—Building off existing success with virtual fencing, this 6,000-acre project focuses on protecting sensitive creek corridors through precision management of cattle.

Partners: PERC

Wildfire Mitigation

Knoxville Wildlife Management Area, California—This project aims to reduce fire risk and improve landscape health by reintroducing strategic grazing on 5,200 acres to challenge existing land management narratives.

Partners: PERC, University of California Davis, Wood Ranch

Additionally, PERC is also supporting three other virtual fence projects outside our Virtual Fence Conservation Fund:
Greater Sage Grouse Habitat

Box X Ranch, Montana—Located within a key region for greater sage grouse breeding ground and habitat, Box X uses virtual fencing to ensure adequate timing and density of grazing patterns to support sage grouse populations. Additionally, the ranch aims to remove physical fences entirely for the benefit of pronghorn migration.

Partners: PERC, World Wildlife Fund

Grazing Improvement and Riparian Protection

Multiple ranches, Montana—This project will deploy virtual fencing across private and public lands owned and leased by the J Bar L, Martinell, and Matador Ranches in Montana’s Centennial Valley. This project aims to improve soil health, improve water quality through riparian filtration, and potentially improve predator conflict management.

Partners: PERC, The Nature Conservancy, Noble Research Institute

Big Game Migration

Pitchfork Ranch, Wyoming—Located within a major migration artery for the regionally significant Cody Elk Herd and Carter Mountain Pronghorn Herd, this project will collar cattle to assist big game migration and reduce livestock conflict with grizzly bears and wolves.

Partners: PERC, Greater Yellowstone Coalition, Ricketts Conservation Foundation, Beyond Yellowstone Living Lab

Workshop

Convening Industry Leaders

In 2024, PERC and the Beyond Yellowstone Living Lab co-hosted the largest virtual fencing workshop of its kind in Bozeman, uniting experts across technology, agriculture, government, and conservation communities to discuss the latest developments in the field and analyze how the game-changing technology could be applied to support wildlife conservation. Learn more about the workshop.

Key Recommendations
  • Integrate virtual fencing into federal conservation programs
  • Promote flexibility in federal programs and grazing rules
  • Streamline permitting and reduce regulatory barriers
  • Improve agency coordination and consistency
  • Establish and fund pilot projects in high-value conservation areas
