Who is responsible for managing weeds in NSW?
NSW Department of Primary Industries - the primary government agency for weed control in NSW. It is responsible for implementing the NSW Noxious Weeds Act 1993.
Local control authorities - responsible for enforcing the control of noxious weeds on private lands and for undertaking weed control measures on council-managed lands.
The National Parks and Wildlife Service - manages weeds on national parks and reserves, in collaboration with other groups and agencies. Under the Threatened Species Conservation Act 1995, the NPWS is responsible for developing threat abatement plans for weeds that have been listed as key threatening processes. A summary of some of the weed control programs undertaken by NPWS can be seen in the report Protecting our national parks from pests and weeds.
Weed control methods
The method you use to control environmental weeds depends on the species of weed being managed, the levels of weed infestation and the resources available (time, labour, equipment and finances).
Biological control/Biocontrol - aims to reduce the effect of weeds by introducing their natural enemies. In Australia national research on biocontrol is carried out by CSIRO and various government agencies. In NSW, NSW Department of Primary Industries also does biocontrol research. Biocontrol programs are regulated by the Biological Control Act 1985.

Chemical control - Herbicides are an important tool for managing weeds. Many modern herbicides are very selective, effectively controlling only specific weeds, leaving other plants unharmed. Herbicide use requires specialised knowledge and training and any herbicide application must, by law, comply with label directions.

Mechanical control - methods include hand-pulling, slashing, digging, grubbing, bark-stripping, felling and bulldozing. These methods may also be combined with burning, tilling or burial of the weeds.

Integrated weed management - Integrated weed management (IWM) is likely to be most effective in controlling weeds. It involves a sustainable approach to long-term management of weeds using a combination of techniques such as biological control, cultural practices, mechanical and chemical control and habitat manipulation. IWM is designed to minimise economic, health and environmental risks.
