Weeds threaten the survival of our local native flora and fauna, overtaking indigenous plants for light, nutrients and water. They can significantly disrupt native wildlife habitats and ecosystems, which can leave species without food and shelter.
Machinery, birds, animals, wind or dumped garden cuttings can contribute to spreading weeds.
- Accidentally or intentionally introduced foreign plants
- Native plants that became weeds from poor management or outside their natural area
The environmental, economic and social impacts of weeds:
- Smother and prevent regrowth of native plants
- Reduce biodiversity
- Control costs
- Loss of open spaces
- Increased fire risk
- Decline to landscape and water quality
- Harbour pests
- Choke waterways, increase flooding
- Alter hydrological and nutrient cycles
Our list of environmental weed species(PDF, 195KB) shows invasive species that you should avoid planting and trying to remove if found.
Some weed species may be referred to as a ‘Noxious Weed’ under the Catchment & Land Protection Act 1994. They must be removed and prevented from spreading.

City of Kingston takes an integrated approach to weed management, using a range of control techniques including hand weeding, steaming, controlled burning and herbicides.
In high-traffic areas such as playgrounds and childcare centres, only manual weeding and steaming are used. Off leash dog park weed management practices include a combination of steaming and hand weeding.
Melbourne Water use an integrated weed management approach at the Quiet Lakes and Tidal Waterways. This approach consists of mechanical raking and herbicide treatment.
Our use of herbicides is guided by the Australian Pesticides and Veterinary Medicines Authority (APVMA) and WorkSafe.
The APVMA and WorkSafe guidelines state that products containing glyphosate can be used safety if directions are followed on the Safety Data Sheet and labels.
For more information, see our report on the use of Glyphosate for weed management.
