Foundations of Virtual Fencing: Exploring the Complexities and Challenges

Across the Western United States, ranchers and land managers rely on thousands of miles of physical wire fencing to manage livestock on extensive rangelands and pastoral systems (Hayter, 1939; Netz, 2004). This type of fence has improved rangeland conditions in many places by allowing the implementation of various grazing systems (Holechek et al., 2011). However, wire fencing can fragment landscape connectivity, pose risks to wildlife, require significant financial investment, and offer little flexibility to implement adaptive management strategies (e.g., adjust pasture size, manipulate grazing distribution, limit potential for over-use, avoid sensitive habitat) within a given pasture (Jakes et al., 2018).
