Pest animals and weeds can interfere with the natural processes of the environment and threaten productivity, ecosystems and the biodiversity of an area. Identifying and controlling pests and weeds can be one of the largest tasks a landholder faces on their property. Knowing what weeds you have and how they can be managed will help you to prioritise your management actions and assist you to achieve faster, cheaper and longer term results.


When undertaking weed control on a property, a good way to start is to work from good areas to bad.

1. Start in your best area, this might be an area with only a light or scattered infestation.
2. Remove any scattered weeds that are on the fringes of native habitat areas.
3. Work towards heavier infestations of weeds (or as per your property management plan).
4. Plant local native plants in cleaned areas to increase competition and reduce the likelihood of reinfestation (maintenance will still be required).
5. As time and money allow, continue clearing the dense weeds, ensuring you are maintaining the previous areas before taking on more.

Prioritising weed control - try to tackle weeds that fall into theses five categories first:

  • Isolated patches or individual weeds (these can be the quickest to deal with);
  • Declared weeds (weeds you are legally required to control) according to class and legislation requirements;
  • Weeds at the top of a hill or catchment (different weeds often require different control techniques and chemical application methods);
  • Weeds in waterways.

By prioritising your management actions and planning your activities, you will achieve greater long term results sooner and at a reduced cost.

Hint - general rule, it is important to stay flexible and take advantage of opportunities (eg. after floods, fires, or when equipment/machinery becomes available). Biosecurity has a list of declared pest and feral animals.

Often it is the resulting damage of the pest that is evident, rather than the pest themselves. Either way it is important to note both the damage caused and any sightings of pest species. Generally no matter what the pest problem, an integration of methods, including poison and trapping is best.

Local governments often carry out baiting and/or trapping programs. By being aware of when these occur and timing with your own pest control program, the results will be better. Collaborating with neighbours will also achieve a better result.
