About weeds
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 billions of dollars each year. They:
- compete with crops, pasture, livestock, and wildlife
- contaminate and degrade our production resources
- reduce the value of the natural environment
- may cause health problems.
Invasive plant species must be prevented from establishing and spreading in SA. Read the plant policies that support on-ground decision making for landowners and industry.
