Pest plants (invasive weeds) pose a serious threat to gardens, farms, orchards, plantation forests, native bush, wetlands and sand dunes. 

Many common weeds are not invasive and pose no serious threat - they are simply a nuisance. Our focus is not on common weeds, but on a small number of high risk weeds that are extremely invasive and damaging.

Many invasive pest plants are species that have escaped from gardens and ‘gone wild’. They can be spread through green waste dumping or when the seeds are eaten and processed by birds. Fixing the damage resulting from uncontrolled invasive weed spread could cost our region millions of dollars each year.
