Opinion: Virtual cattle fencing offers a multiple-benefit solution for ranchers and helps migrating wildlife

Western ranches in the United States include thousands of miles of barbed wire fencing, which has both positive and negative effects. GPS fencing could help ranchers strike a healthier balance while cutting business costs, writes Bruce M. Beehler in his opinion for The Washington Post.

Rangeland fencing is "an important tool for managing herds, rotating grazing areas, protecting environmentally sensitive wetlands and stream corridors, and keeping cows off highways," Beehler points out. "But it’s also harmful to wildlife populations, including deer, pronghorn, bighorn sheep and elk, as well as game birds such as the greater sage-grouse."

The idea behind GPS-based virtual fences is similar to "Invisible Fence," which uses buried wire to keep dogs in their yards. Similarly, virtual cattle fencing "uses GPS, cellular technology and a mapping app that allows ranchers to draw cow-proof fence lines on their computer or tablet," Beehler explains.

While the new system requires an initial investment in collars and cell service to install, Beehler believes it offers ranchers enough benefits to justify the initial price tag. For one, they won't have to repair nearly as much fencing, which is time-consuming and expensive for farmers and tax payers. 

For wildlife, removing barbed wire fencing from migration corridors will prevent animal suffering and death. Beehler adds, "One study in Montana found that, on average, one wild ungulate got tangled in fencing every 2.5 miles of fencing per year."

While the system is designed to keep herds within designated grazing lands, it offers a huge secondary benefit. Beehler writes, "With a glimpse at the mapping app, ranchers can see the exact location of every one of their cows in real time."

Virtual fencing won't replace all physical fencing, "especially along highways and to keep bulls from wandering into a neighboring herd," Beehler explains. 

But for every mile of barbed wire that virtual fencing replaces "costs will decline. . . and as a result the annual cost of maintaining a herd will fall, increasing profit margins," Beehler adds.
