Identifying and controlling weeds
We must reduce the impact of weeds to maintain the productivity of our primary industries, protect our natural environments, and sustain the health and wellbeing of our communities.
Search for weeds that pose a serious risk to our environment and primary industries, and learn what to do about them.
Report unusual weeds found on your property to your local Natural Resources Centre to avoid them becoming established.
Find out how to control weeds via early intervention or biological control methods.
Learn what you need to do with declared and alert weeds found on your property in South Australia.
There are state and national programs to assist with overseeing, destroying or containing weeds, including weeds of national significance.
Read the plant policies that support on-ground decision making for landowners and industry.
About weeds
Weeds are plants that grow wild and have negative impacts on primary industries, native vegetation, or human health.
Invasive plant species must be prevented from establishing and spreading. They cost Australian agriculture billions of dollars each year by:
- competing with crops, pasture, livestock, and wildlife
- contaminating and degrading our production resources
- reducing the value of the natural environment
- causing health problems.
