Presenter: Kate Helmstedt (QUT)

Optimal decision-making is crucial in natural resource systems that we manage for multiple outputs -- economic, social, and ecological benefits. We have a long history of questionable ecological decisions (like intentionally introducing rabbits to Australia and reindeer to sub-Antarctic islands), and ever-growing land requirements for anthropogenic uses. These issues couple to put native ecological systems in pretty dire situations, especially in Australia. I'll cover a few ways I've used operations research to guide better ecological decision-making for management of invasive species, threatened species, and land-use, and introduce some of the complexities that arise from managing ecological systems.
