Virtual fencing is a new technology that employs GPS collars to keep animals in "virtual" pastures—so instead of using physical fences, the fence lines are drawn on a computer screen, and the collars direct the animals' movements through sound cues and mild electrical stimulation. This saves ranchers on labor and materials, allows more adaptive and flexible pasture management, and allows free range for wildlife. The Nature Conservancy, whose mission is to tackle climate change by protecting land and water and fostering a healthy food system, is partnering with ranches across the US to help ranchers adopt virtual fencing systems. We talk to William Burnidge, deputy director of The Nature Conservancy’s Regenerative Grazing Lands strategy in North America, and Danna Camblin of Camblin Livestock, whose ranch has been successfully employing virtual fencing for the last few years.
