Abstract Virtual fencing (VF) is an emerging precision-livestock technology that uses GPS-enabled collars to manage cattle without physical barriers, relying on cattle’s associative learning behavior to guide them and offering a flexible, potentially cost-effective alternative to traditional fencing. Our research group at the Eastern Oregon Agricultural Research Center (EOARC) in Burns, Oregon, has evaluated VF efficacy, cattle learning, behavioral, and physiological responses, and potential applications for rangeland and cattle management using VF. Across multiple studies, naïve beef cows rapidly learned to identify VF boundaries, as indicated by a marked decline in auditory and electric stimuli over time. Physiological and behavioral assessments showed no major negative impacts on stress- or inflammation-related markers, with cows relying primarily on auditory cues after initial training to the VF use. The use of VF effectively contained cattle within designated areas and excluded them from sensitive or high-risk zones, including recently burned sagebrush steppe, where forage utilization in burned areas was reduced to less than 3% compared with approximately 70% in controls with no VF use. The use of VF to create targeted fuel breaks (fire protection/fighting) also demonstrated successful manipulation of grazing distribution, reducing fine fuels by approximately 40–60%. Collectively, these studies demonstrate that VF is an effective tool for improving grazing management, protecting sensitive areas, and supporting wildfire mitigation efforts without disrupting cattle behavior and welfare. Ongoing research aims to refine VF use in riparian conservation, fuel-load reduction, broader rangeland and management applications, and to understand the implications of cattle personality on VF responsiveness and efficiency.
