Virtual fence (VF) has the potential to revolutionize grazing systems by allowing dynamic control of livestock distribution and duration. The system uses invisible barriers, established by Global Positioning System (GPS) coordinates, to influence livestock movement with a combination of auditory and electrical cues without a physical fence. However, it can be also be complicated and expensive.
This digital guide was created to empowers ranchers and land managers to effectively evaluate and use VF for improved rangeland management. Explore the foundations of VF factsheets, watch the videos, access geospatial resources, and explore handouts from workshops and webinars to better understand a VF system.
Foundations of VF
- Virtual fence (VF) is an emerging precision livestock management tool with multiple interconnected components.
- Virtual fence lines are created in VF software, which requires a digital map of an entire ranch or land management area.
- How livestock recognize and interpret the auditory and electrical cues can limit potential risks for animal health and welfare.
Exploring the Complexities and Challenges
[coming soon!] Special consideration is needed when training livestock, designing fences, managing incentives, and gathering livestock.
The Financial Implications of VF
[in progress] Economic pros and cons of VF implementation to better understand the financial benefits and risks of the technology compared to tradition fencing.
Strategies for Collar Management
[in progress] Battery life, collar disposal, strategies for collection in the field, and data organization.
Collar Fit
[in progress]Equipment needed, strategies for proper fit, and safety when placing virtual fence collars on livestock.
Tools
- Explore the boundaries of virtual fencing with handouts and presentations from the 3-part workshop series.
- Compare the cost of VF systems and physical fence in different scenarios.
- Plot the best location for a single base station. Requires ArcGIS Pro with the Spatial Analyst extension enabled.
- The Arizona Geographic Information Council curates GIS data resources for Arizona and other western states.
- The U.S. Forest Service maintains digital rangeland data on boundaries, natural resources, and more.
- The Bureau of Land Management shares geographic data and content that can be downloaded.
