Aim: 
To investigate whether the restoration of dingoes might provide a net benefit for rangeland vegetation and the profit margins of cattle pastoralists
Type of Study: 
Simulation
Key Results: 
Results demonstrate that top-down herbivore control by dingoes should allow cattle pastoralists to profit from conservative stocking densities while reducing the risk of pasture over-utilization
Treatments: 
Cattle, cattle + kangaroos, cattle + kangaroos + dingoes
Response: 
The increase in pasture biomass due to dingoes was greatest at low stocking densities, while improvement in profits was strongest at intermediate stocking densities. At high stocking densities, the abundance of kangaroos was low, so if dingo abundance exceeded that required to control kangaroos, some dingo baiting could produce small economic gains.
Models: 
optimisation and sensitivity
