Australians spend lots of time and money every year combating weeds.
This protects our natural landscapes, agricultural lands, waterways and coastal areas.
Throughout Australia, weeds are spreading faster than they can be controlled.
Weeds of concern
A large percentage of weed species were originally imported for use as garden ornamentals.
Purchasing seeds and bulbs online is risky as potentially invasive plants could enter Australia
For example, Mexican feather grass (Nassella tenuissima) is a highly invasive ornamental grass that could dominate large areas of Australian woodlands and grasslands. Despite being banned, this plant is available for sale in garden centres and online through online trading sites.
Weeds of National Significance
32 Weeds of National Significance have been identified by Australian governments based on their invasiveness, potential for spread, and environmental, social and economic impacts.
Take a look at the main species we are trying to control:
Did you know?
Impact on plant production
1000 species of weeds directly impact plant production in Australia
Impact on natural environment
2300 species of weeds have an impact on the natural environment in Australia
Cost of weeds
Controlling weeds costs Australian agriculture more than $4 billion annually
An im-purr-fect plant
While the bright, showy flower of this vigorous vine may be attractive, these invasive plants qualities are anything but. Jerry Coby-Willaims introduces us to the cats claw creeper (Dolichandra unguis-cati), a garden escapee that is anything but ‘purr-fect’ in our bushland spaces. (ABC, Gardening Australia)
