Weeds that are regulated under the Landscape South Australia Act 2019 are known as 'declared weeds'.

They become declared weeds because of their negative impacts on primary industries, native vegetation and/or public health.

Declared weeds have restrictions on their movement, sale, notification and control. Landowners are responsible for managing them in South Australia.

How to ID your weeds

Identifying weeds helps you find out the best ways to control them. To do this, download and use the free Weed Control app.

If you need more help you can:

  • Email us photos of the whole plant with a close up of leaves and of the flowers (or other reproductive parts such as petals and nectar glands). Grasses are the most difficult to identify, so a close-up of their seeds is helpful.
  • Take a sample of the plant with the flower/reproductive part to your local plant nursery. Here's a list of native plant nurseries in metro Adelaide.

If you have a bush block, and you’d like advice on how to manage your weeds, contact us to discuss this and we might be able to arrange a free property visit.
