Landcare Research

Invasive weeds are one of the most serious threats to biodiversity and sustainable development in the Pacific region. Biocontrol is likely to be the only feasible way of managing many widespread weeds, but is not always appropriate or successful. With so many weed species to tackle and inevitably limited resources, prioritising where to direct control efforts most effectively is of key importance. Landcare Research recently developed a framework for the Australian government that allows the best and worst weed targets for biocontrol to be identified.

Common mynas have been introduced (often as biocontrol for insects) or colonised many islands in the Pacific. They are one cause of decline in some native bird species such as endemic kingfishers, and are a pest when they damage fruit and compete for food to put out for domestic animals.
