Weeds in Australia

Identifying weeds

Identifying weeds

This part of the website can help you identify some of the weeds that may be a problem in your area. There are several ways to search the weeds database:

About the weed identification tool

The weed identification tool is designed to provide information about terrestrial and aquatic invasive plant species (weeds) that are on a national weed list, or are legislated against in a state or territory. The weed identification tool is not a complete list of all weeds in Australia. At this stage profiles are not available for all invasive plant species in these categories, but they will be regularly added to the tool.

The weed identification tool provides information on what the species looks like, its distribution, habitat, reproduction and disperal, taxonomy, growth, impacts, control methods, origin, legislative status in states and territories, its status on national weed lists and references to other information on the weed. The information has been compiled by summarising information from a range of sources and contributors.

Plants that are perfectly safe to plant in one part of the country can be an environmental or agricultural problem in another. Plants should be selected to suit the geographic area in which they will be planted. More information on what is a weed in your area is available from local councils, state or territory weed management agencies and from nurseries and other plant retailers.

Declaration of a noxious weed under state or territory legislation can mean different activities are required for the management of a weed, dependent upon the state or territory in which a weed is declared, and on the declaration class that the weed has been listed in. More information on the type of declaration of individual weed species, and on the legislation for each state and territory, can be found at Weeds Australia Noxious Weed List .

The location field in the species profiles only notes which states or territories the weed has become naturalised in, that is where weeds have a population that is able to reproduce and sustain itself. The weed could still be present, but not naturalised, in other states or territories.

Further information

There are many resources available to help you identify weeds and plants in general. The web sites for the Australian National Botanic Gardens , the Australian National Herbarium and the Centre for Australian National Biodiversity Research may be useful if you would like to learn more about plant identification.
