Environmental and sustainability projects

The City of Stirling undertakes a number of environmental projects in its bushland, wetland and coastal reserves each year as part of its capital works program. 

Current and recently completed environmental projects in the City of Stirling are listed below.

Bushland, wetlands and dune restoration

These restoration projects are critical to ensuring the long-term survival of our native flora and fauna and their habitat.

  • Brushfield Way drain restoration project
  • Bushland protection fencing
  • Bushland revegetation projects
  • Lake Gwelup restoration
  • Coastal revegetation projects
  • Watermans Bay dune restoration project
  • Signage upgrade
  • Paths and beach access step upgrades
  • Jackadder Lake wetland margin restoration
  • Basalt Silver Topaz Bushland enhancement project.
Fencing and track upgrades

Fencing and track upgrades

To date the Natural Areas team have upgraded fencing and access tracks in 40 bushland reserves across the city  including Carine Regional Open Space, Dianella Regional Open Space, Richard Guelfi Reserve, Yokine Regional Open Space, Star Swamp, Lake Gwelup, Princess Wallington Reserve, Trigg Regional Open Space and Cottonwood Crescent Reserve.

Lake Gwelup

Lake Gwelup restoration

A long-term project that will see the removal of invasive weeds such as Typha, and replaced with native Baumea sedges. The project will restore wildlife habitat and improve the aesthetics of the lake.

Flora and fauna survey

Natural Areas undertakes flora surveys every two years to monitor the progress of at risk species such as orchids. It is estimated that orchid populations have declined by 75% across the city due to people picking them. 

The City's Natural Areas team undertake annual fauna surveys to track the progress of native wildlife, especially those species that are threatened, endangered or at risk due to human impacts.

Rusty Spider Orchard

Rusty Spider Orchid

Unlike most plants, orchids do not grow back once they are picked.

Quenda survey

The Southern Brown Bandicoot or Quenda is a marsupial in decline and listed as Threatened - Priority 5 by the Department of Biodiversity, Conservation and Attractions.

They are found in four of the City’s bushland reserves as well some coastal dunes. Quendas are easily stressed and disturbances from people or their pets can death or females ejecting infants from their pouch.


Protecting Quenda's

The City asks your assistance by staying on tracks, avoid walking through the bush, keeping dogs on leash, and not allowing domestic cats to enter bushlands, wetlands or coastal dunes.

There are a variety of community groups that aim to protect the environment through reducing, reusing and recycling waste.

We are continually working to reduce energy and carbon emissions, water consumption and adapt to a changing climate.

Current and recently completed sustainability projects and initiatives are listed below.

Climate Change Adaptation

The City is taking action to adapt to climate change. Our Climate Change Adaptation Plan uses a risk management approach to identify what climate risks are a priority and what actions are required.

It focuses on monitoring, implementing and reporting key initiatives within natural and built environments and through community programs.

Energy and carbon emissions projects

Our emissions reduction projects include installing solar energy systems, geothermal energy, LED lighting replacements, air conditioning upgrades, purchasing more efficient vehicles and using alternative fuels.

The City was also the successful recipient of funding from the Australian Government to deliver energy efficiency education programs and undertake energy efficiency upgrades to the following facilities:

  • Administration Centre - Stirling
  • Stirling Leisure Centres - Terry Tyzack Aquatic Centre - Inglewood
  • Stirling Leisure Centres - Leisurepark - Balga
  • Operations Centre - Balcatta
  • Stirling Leisure Centres - Herb Graham Recreation Centre - Mirrabooka
  • Stirling Libraries - Inglewood
  • Stirling Libraries - Mirrabooka
  • Stirling Libraries - Scarborough.

Since implementing the energy efficiency upgrades, there has been a 2% reduction in total energy usage across the City.

Fleet Emissions Reduction Action Plan 2015 - 2020

City has identified key areas of its business that generate greenhouse gas emissions and is actively implementing strategies to reduce or mitigate those emissions. 

The City’s Fleet generates approximately 27% of all greenhouse gases that the City emits. This Action Plan details tangible outcomes to reduce vehicle fleet emissions working towards a zero emissions target for the City’s fleet.

The City aims to implement actions that will contribute towards a zero emissions target for fleet operations. Actions will be delivered across three broad objectives that will see the City:

  • Establish an optimum configuration of fleet vehicles and support services that would produce the least emissions
  • Lead by example in sustainable fleet management
  • Support and enable behaviours that reduce fleet emissions.

Reducing water consumption

The City works hard to reduce unnecessary water consumption and is now recognised and endorsed by the Water Corporation as a Gold Waterwise Council.

In addition, the City’s water smart parks program is reducing water use by replacing surplus grass with native plants, improving irrigation systems, and using moisture probes so we only water when the soil is dry. To view the City's Water Smart Parks Program, click here.

Water consumption

Water consumption in the City of Stirling

  • Each year the City uses around 155 million litres of scheme (drinking) water to operate its buildings and provide services for residents. Scheme water represents just three per cent of the City's total water consumption
  • The City uses 5.3 billion litres of groundwater annually, mainly to irrigate parks and reserves in the community. Groundwater accounts for 97 per cent of the City's total water consumption
  • Stirling residents use a total of over 20 billion litres of scheme (drinking) water each year. Nearly half of all this water is used in the garden to irrigate water-hungry plants and lawn.
