Dumping of waste in reserves is illegal, and could cause weed seeds to germinate and invade the bushland, so please report any dumping you come across. Also, find out about bushland degradation, native tree decline, dieback fungus, and how to manage these issues.

Rubbish dumping

Dumping of garden and domestic waste is a regular occurrence in some reserves. Not only does this look unsightly, but garden waste also could be carrying weed seeds which could germinate and invade the bushland.

The City of Stirling conducts regular patrols to remove bushland rubbish and garden waste as quickly as possible.

You can download the Rubbish dumping in bushland brochure (PDF) for more information on:

  • Environmental consequences
  • Common types of rubbish dumped in the City's bushland
  • Proper ways to dispose of your rubbish and other waste
  • Useful contact numbers
  • Information on reporting rubbish dumping.

Please assist the City by disposing of your garden waste appropriately and reporting incidents of bushland rubbish dumping immediately.

Managing the decline in native trees

Please download the Preventing and managing native tree decline brochure (PDF) for information on:

  • Causes of native tree decline
  • How to tell if your trees are stressed and what healthy trees should look like
  • Importance of native trees
  • The long term solution.

Bushland degradation

Bushland degradation is a problem caused by weeds, dieback, rabbit activity and other factors.

The City of Stirling attempts to manage these threatening processes through a number of projects and initiatives. However this is not enough, as many bushland remnants have become severely degraded and need to be restored through revegetation.

The City undertakes numerous revegetation projects on a yearly basis through our capital works program, budget allocations and conservation volunteer's efforts.

Many reserves are also listed as 'unsustainable', as they are highly vulnerable due to their small size. To rectify this, parks with numerous small bushland 'pockets' are amalgamated to form larger bushland areas.


Dieback (Phytophthora cinnamomi) is a waterborne fungus common in the southwest which attacks the roots of native plants.

The fungus usually spreads slowly via water in natural areas, but it can be transported across large distances in the soil that is:

  • Being transported for infilling purposes
  • Trapped on tyres, undersides of vehicles or hiker's boots.

There are a number of reserves which have been infested with dieback, and City of Stirling has a number of initiatives in place to monitor and prevent it from spreading:

  • Signage in some infected areas informs users of the presence of dieback and what measures they can take to reduce the spread
  • Boot cleaning stations are being installed and hikers are encouraged to use them when entering and exiting the reserve to minimise the spread of dieback
  • Natural areas currently infected with dieback are undergoing phosphite treatment, which will help build their resistance against the fungi.
