Precision pastoralism‐advanced systems for management and integration of livestock and forage resources in the semi‐arid rangelands in south eastern Australia
Precision pastoralism involves the application of new technology to manage animals according to individual requirements and to assist the management of rangeland resources by matching forage supply with forage demand.Individual animal management is achieved through the capacity to identify and weigh individual animals as they enter a watering enclosure, telemeter the data to a remote computer, and remotely activate drafting gates based on analysis of a quality assured data set.Alternatively, any other individual attribute (e.g.reproductive status) may be used as basis for remote drafting.Improved management of forage resources is achieved through a capacity to provide probabilistic estimates of future sustainable stocking rates, and ground cover under the current stocking rate, by forward projection of pasture growth from current conditions.Projections are derived from a pasture growth model parameterised for individual vegetation types within a specific property, and applied at the paddock level.Decisions to increase or decrease stocking rate can then be considered in an objective risk management context.
