Applying search theory for eradicating invasive species

Search theory will be used to improve the efficiency, probability of success and cost-effectiveness of control and eradication programmes for terrestrial and marine invaders using information on their spatial distribution, population dynamics and detectability. Optimal monitoring strategies will be developed for each stage of an eradication program: (1) delimitation of the spatial extent of an infestation; (2) removal of invasive organisms, and (3) determining an area to be free of invasive organisms. Three case studies will provide real-world proof-of-concept. The analytical and empirical approaches developed and validated in this study will be broadly applicable to other invasive species that threaten Australia s unique biota.
