Australia is lucky to be free from many of the world’s most damaging plant pests. Exotic plant pests are capable of damaging our natural environment, destroying our food production and agriculture industries, and some could change our way of life. Australia’s biosecurity system helps protect us from exotic plant pests. The Department of Agriculture, Water and the Environment manages this system with state and territory ​governments, industry and the community. The Plant Health Committee has recently reviewed the National Priority Plant Pests that are exotic to Australia, under eradication or have limited distribution. These are the focus of government investment and action, including funding through the Priority Pest and Disease Planning and Response. While by no means the only plant pests of biosecurity concern, the National Priority Plant Pests serve to highlight the sort of threats Australia faces.

New Zealand Parliamentary Commissioner for the Environment, Simon Upton, is calling for the Government to lift its game in protecting native ecosystems from the thousands of exotic plants spreading throughout Aotearoa New Zealand. “Rampaging weeds pose a deadly threat to our native ecosystems by smothering, outcompeting and preventing regeneration of native plants,” the Commissioner says in a report released today. The report, Space invaders: A review of how New Zealand manages weeds that threaten native ecosystems, explains that protecting our native ecosystems from being overrun by weeds not only helps our native taonga plants, but also saves crucial habitat our taonga fauna need to survive.

This guide will assist Pacific island practitioners to use the costs that result from invasive species incursions to gain support to fund prevention, management, restoration, research, and outreach. For more knowledge resources, please visit the Pacific Battler Resource Base.

This guide explains how natural enemies (typically invertebrates and pathogens from the native home range of the pest) can be used to control serious invasive weeds in the Pacific. The use of natural enemies is the most cost-effective method of controlling widespread weeds in the Pacific. It is particularly important in the Pacific context where local capacity to manage such widespread problems is limited. For more knowledge resources, please visit the Pacific Battler Resource Base.
