Pest Plants

Environmental weeds are the most serious threat to the survival of indigenous (locally native) flora and fauna. Weeds out compete indigenous plants for light, nutrients and water, they are climatically suited to their new environment and can thrive because of the absence of natural diseases, insects and pests. They have the ability to change habitats and ecosystems, leaving some species of our native wildlife without habitat (food and shelter). 

Weeds are:

  • foreign plants accidentally or intentionally introduced into Australia,
  • v native plants that have become weeds due to inappropriate management, or because they are outside of their normal range

Weeds can be spread in a number of ways including machinery, birds, animals and wind or by people dumping garden cuttings into our bushlands, grasslands and onto the foreshore reserve.

Weeds have significant environmental, economic and social impacts including:

  • smother indigenous vegetation
  • prevent regeneration of indigenous plants
  • reduction of biodiversity
  • cost of control
  • degradation to natural landscape
  • loss of open space for recreational activities
  • degradation of water quality
  • increased risk of fire.
  • reduce habitat and displace native fauna
  • harbour pest animals such as rabbits and foxes
  • choke waterways, increasing flooding and reducing water quality
  • alter hydrological and nutrient cycles.

Some species of environmental weed may also be designated as a ‘Noxious Weed’ under the Catchment and Land Protection Act 1994, and therefore must be removed and their growth halted to prevent them from spreading. contact Agriculture Victoria on 136 186 or visit the Agriculture Victoria website for more information on noxious weeds.
