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.
