Weeds in South Australia
Weeds are plants that grow wild and have negative impacts on primary industries, native vegetation or human health. The cost of weeds to Australian agriculture is more than $4 billion each year.
Many weeds, particularly those that invade bushland, rivers and coasts are escaped garden plants. Weed risk assessment is now used to determine the weed potential of new plant introductions to Australia.
Declared Plant Review Phase 4
Phase 4 of the Declared Plant Review is now underway.
South Australian land owners and plant growers, including:
- bush managers
- local councils
are invited to have their say on proposed changes to managing 9 weeds.
Visit the YourSay website to have your say, view a summary of the changes and for more information.
Consultation closes on Friday 3 June 2016.
Declared plants are weeds that are regulated under the Natural Resources Management Act 2004 due to their threat to primary industry, the natural environment and public safety.
Plants are declared under the provisions of the Act relating to their movement, sale, notification and control.
Natural Resources Management boards oversee control programs for declared plants in each region, through the Department of Environment, Water and Natural Resources.

Some declared plants are also alert weeds because they are not yet established in South Australia and pose a serious threat.
Early detection is important so the plant can be destroyed before it becomes a serious problem.
Statewide management plans
Plans for specific weeds have been prepared to guide coordinated management programs:
- State Opuntioid Cacti Management Plan ()
- Management Plan for Silverleaf Nightshade in South Australia ()
- Buffel grass information page and State Buffel Grass Strategic Plan. ()
Weeds of National Significance (WoNS)
WoNS are Australia’s most invasive plants. They have proven social, economic and environmental impacts that require national action to manage. There are national programs and strategies for each WoNS.
