A-Z Noxious Weeds

In Sydney's northern region many bushland reserves are under threat because of the invasion of plants escaping from backyards and gardens. Common garden species can be spread by birds eating the seed or people tossing garden clippings into the bush.

Some exotic species are vigorous invaders, growing faster than native species and usually producing much more seed.

Once weeds take over an area the character of the bushland changes, diminishing habitat for native wildlife and altering fire regimes.

At the community level, Bushcare groups work with Council to eradicate noxious weed infestations and regenerate bushland with indigenous species.

However, weeds do not recognise local government boundaries and to this end North Sydney Council is a member of the Noxious Weeds Committee - Sydney North, which coordinates a regional approach to the problem. Refer to the Weeds in Australia government website

  1. The control objective for plants to which Class 1 applies is to prevent the introduction and establishment of those plants in NSW;
  2. the control objective for plants to which Class 2 applies is to prevent the introduction and establishment of those plants in parts of NSW;
  3. the control objective for plants to which Class 3 applies is to reduce the area and the negative impact of those plants in parts of NSW;
  4. the control objective for plants to which Class 4 applies is to minimise the negative impact of those plants on the economy, community or environment of NSW;

*A noxious weed that is classified as a Class 1, 2 or 5 noxious weed is referred to in this Act as a "notifiable weed".

** Unless being maintained as a formal hedge in which all fruits and/or flowers and/or seeds are continuously prevented from forming, the plant should be removed/fully controlled.
