Weeds and Noxious Plants


Morning Glory

Weeds are plants that grow in places where they don’t belong. Weeds classified as noxious must be controlled or removed under the NSW Noxious Weeds Act 1993. Often they cause a problem to human health, agriculture and the environment. 

There are also Weeds of National Significance (WONS), considered the worse weeds in Australia!

Weed Control

As a general rule any weed should be controlled before flowering. Any part of the plant capable of reproducing, such as tubers, rhizomes, seeds and berries should be placed in a bag and removed off site. Other debris can be mulched on site. 

Sydney North Regional Weeds Committee

Warringah Council is a member of the Sydney North Regional Weeds Committee. This committee assists councils to work together in targeting noxious weeds that are particularly problematic to residents and the local environment.  

The committee's aim is to coordinate weed control actions and resources to prevent further spread of weeds, and to protect the most important assets that we have – our endangered ecosystems, waterways, agricultural and critical habitat corridors.
