摘要: Free-ranging livestock play a pivotal role globally in the conversion of plant tissue into products and services that support man's many changing lifestyles. With domestication came task providing with an adequate plane nutrition while simultaneously managing vegetation for sustainable production. Attempting to meld these two seemingly opposing management goals continues be major focus rangeland research. Demand multiple goods from rangelands today requires production make smallest possible 'negative hoof-print'. Advancements global navigation satellite system, geographic information systems, electronic/computing technologies, coupled improved understanding animal behaviour, positions virtual fencing (VF) as increasingly attractive option free-ranging livestock. VF offers alternative conventional by replacing physical barriers sensory cues control animal's forward movement. Currently, audio electrical stimulation are employed. When becomes commercial reality, manual labour will replaced large part cognitive real-time prescription-based distribution is robust, accurate, precise flexible. The goal manage ecosystems optimally soils, plants, herbivores addition animal' sm icroflora. However, maximising benefits require paradigm shift using 'virtual herder' rather than simply tool within static barriers.
