Pests, Weeds & Diseases

Weed Control

The City controls weeds as outlined in the Biosecurity and Agriculture Management Act 2007 and the Weeds Of National Significance agreement as well as controlling additional weed species to preserve amenity and environmental values.

Whilst the City would prefer not to spray herbicide, sometimes there is a need to, and in these instances, we use herbicides with low or no toxicity. The City also encourages the community to assist with weed control, especially in local natural areas. 

There are many local Friends Groups working with the City to aide this. Find out more about Friends Groups here. Further, the City run several Grab-a-gladdie events to target the removal of this particular weed.


Invasive pest animals are introduced species that are, or have the potential to become, established in the wild.  They can threaten farms, parks and natural areas and can impact our environment, our economy and our social amenity.  They predate wildlife, compete for habitat, kill and damage livestock, spread weeds and diseases.  Some of these animals are already established and beyond eradication, for example foxes, rabbits, feral cats, feral pigs; while others are not yet established, for example European wasp, European House Borer but threaten to become established unless measures are taken to control.

The City controls certain pest animals as defined by the Biosecurity and Agriculture Management Act 2007.

Introduced predators such as foxes and feral cats, along with loss of habitat, are key factors in the decline of native mammals and animals including ground nesting birds, pythons and other reptiles. Since European settlement, Western Australia (WA) has seen:

  • 11 mammal species extinctions;
  • seven species disappear from the mainland but remain on a few offshore islands;
  • more than 30 species populations decline significantly or become threatened with extinction.

It is not known what the full impact of the loss of these particular species has been on WA's environment.  The extinction or decline of any species is of great concern for a range of environmental, amenity and ethical reasons.

Below are some resources, information and tips on managing some of the pests, invasive animals, diseases and weeds in our City.
