SA Alert Weeds

What are Alert weeds?

Alert Weeds are pest plants that pose a serious threat to South Australia's primary industries, natural environments and/or people, but currently have little or no impact because they have not yet arrived or may be present here in very low numbers. If, however, they were to arrive in SA and were not detected early, their impact could be severe. A small number of Alert Weeds that have already been found within SA have either been quickly eradicated and no longer occur in the wild (e.g. water hyacinth), or are confined to a small area where eradication is still considered feasible. All Alert Weeds are declared as pest plants under State law in recognition of their serious threat to South Australia (Declared Plants of South Australia brochure). Declared plants are regulated under Natural Resources Management Act 2004 according to their movement, sale, notification and control.

Why focus on Alert Weeds?

Prevention and early intervention are the most cost-effective investments in biosecurity, including for weeds. Once a weed has become well established, eradication is rarely feasible and the weed has ongoing impacts and management costs. Early detection and quick action can therefore prevent Alert Weeds from becoming established in South Australia.

What can we do about Alert Weeds?Weed Alert!

We need to know when they arrive in SA as early as possible. The sooner they are detected the easier it will be to control them.  We need to be on the lookout for new weeds to South Australia, especially State Alert Weeds. If you see a new weed, particularly an Alert Weed, please report it to your local NRM Board.

Where to look for Alert Weeds

Your local NRM Board can provide advice on where and how to look for new weeds. If you do find a plant that you suspect is a new weed please collect a specimen or take a photograph and send to the NRM Board for identification.
