Many of the pastures used by farmers to graze cattle can contain toxic plants that may induce poisoning. While some plants are toxic in quite small amounts, others can be cumulative with damage to internal organs developing over time.
Examples of poisonous plants in Australia include Paterson’s curse and Perennial ryegrass while other countries such as the United States battle plants like poison hemlock.
Traditionally, farmers have fenced off potentially dangerous pastures. However, fenceless farming will allow a grazier to identify problematic areas of pasture and simply draw a virtual barrier around the plants. Livestock with the eShepherd collar would not approach those toxic areas. The virtual fence allows farmers to maximize their land usage and productivity by placing livestock in areas that previously were not usable.
