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 Landscape South Australia Act 2019 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.

District weed strategies

The six Landscape Groups in the SA Arid Lands region, in conjunction with district communities have developed district level strategies to manage priority weeds. The five-year strategies identify priority weeds, outline management actions to reduce the current and potential impacts and detail current best practice control methods, surveying and monitoring activities.

Find out more about Landscape Landscape Groups and the work of the SA Arid Lands Landscape Board.
