Pest plants

Pest plants must be managed because they can have significant impacts on industries and the environment.

Declared pest plants

Pest plants that are a significant threat to agriculture, the natural environment and public health and safety are called declared plants and land owners have a legal responsibility to manage these plants. The Natural Resources Management Act 2004 sets out the legal framework for:

  • banning the sale of declared weeds
  • controlling the movement of declared weeds
  • destroying or controlling infestations of declared weeds 
  • notifying authorities when an infestation is detected.   

More information can be found in Declared plants of South Australia - are they on your land? (574kb pdf) or through Biosecurity SA.
