Weeds, Pests and Diseases

The threat posed to Australian native species by invasive weeds and pest animals is growing. It is now second only to land clearing as the biggest threat to Australia's biodiversity.

Escaped invasive garden plants are the biggest source of agricultural and environmental weeds, costing farmers hundreds of millions of dollars each year. Phytophora, a serious fungal disease, acts like a biological bulldozer destroying forests in Western Australia. Pest animals have played a major part in the extinction of many native animals, with rats causing the extinction of five bird species on Lord Howe Island alone.

WWF has been instrumental in convincing the Australian Government to commit another $40 million to combat the growing weeds problem, toughen quarantine laws to move towards restricting import and trade of more than 3,000 weeds not yet in Australia, list cane toads, invasive garden plants and rats on off-shore islands as key threats under Federal environmental law, and develop in place a national action plan that will remove rats from islands rich in wildlife.
