Council is continuing to monitor the evolving situation with COVID-19. Please see our dedicated webpage for up-to-date information on Council services and advice.

Biodiversity is defined as the variety of all life forms; the different plants, animals and microorganisms, their genes and the ecosystems of which they are a part. The conservation of biodiversity is one of the key principles of sustainability and Councils are required by the NSW Office of Environment, Energy and Science to manage, protect and conserve local biodiversity.

There are a number of small pockets of remnant vegetation throughout the Strathfield Local Government Area, some of which are listed as Endangered Ecological Communities under the NSW Biodiversity Conservation Act 2016. These endangered ecological communities include Castlereagh Ironbark Forest, Coastal Saltmarsh and Swamp Oak Floodplain Forest. The fragmentation of these natural areas leaves them particularly vulnerable, making their management an important priority for Council.

A number of endangered species are found in Strathfield including the Green and Golden bell-frog (Litoria aurea) and the Downy Wattle (Acacia pubescens). Mason Park Wetlands in Homebush also attracts migratory Wader birds from the Northern Hemisphere through Spring and Summer each year.

Council aims to enhance biodiversity across the municipality through forming partnerships with the State and Commonwealth Governments, catchment management groups, bushcare groups, and the local community. For more information on these programs, or conserving biodiversity and native wildlife, please see our Biodiversity Conservation Strategy and Action Plan 2020-2030 attached at the bottom of this page, or visit:

Bird Friendly Backyards

Bird Friendly Backyards

Creating a bird friendly backyard is one way to help to contribute to biodiversity conservation in our community. Birds in Backyards is a research, education and conservation program focusing on birds and the urban environment and was developed by the Australian Museum and Birds Australia.

The Birds in Backyards website provides information about identifying birds, participating in surveys and research, creating bird-friendly spaces in your backyard and about upcoming events such as talks, study programs, presentations, open days and tours.

BirdLife Australia also run a range of educational events at the Birds Australia Discovery Centre in the Newington Armory, Sydney Olympic Park. For more information on upcoming events click here.


Strathfield Council’s “The Fauna of Strathfield Council Local Government Area” is a comprehensive study of parks and reserves within the Strathfield Local Government Area, and assessment of the variety of wildlife present.  The study provides recommendations on how to enhance biodiversity.

A key finding of the study found that Mason Park Wetlands and its surrounding vegetation is the most species-rich reserve within the Strathfield area. This result was largely due to the presence of migratory shorebirds that arrive during spring and summer.

Green and Golden Bell Frog

The Green and Golden Bell Frog is listed as an endangered species. Green and Golden Bell Frogs were once considered common, widespread and abundant along the eastern Australian coastline from northern New South Wales to north-eastern Victoria. However, since the 1960s this iconic species has gone from being one of the most commonly encountered frogs to one of the most threatened.

There are 8 key populations in the Sydney region. The suburb of Greenacre, located within the Strathfield and Bankstown local government areas, is known to support one of these key populations.


Body patterns vary greatly with some individuals being a bright pea green with very little gold marking, while others can be a dull coppery-brown colour. Some individuals may darken to almost black.The underbelly of the Green and Golden Bell Frog is usually creamy white in colour and granular in texture.

Whilst habitat for the Greenacre Key Population of Green and Golden Bell Frogs has dwindled due to extensive residential and industrial development, the population has survived by utilising local features including constructed ponds, drainage depressions, areas of native and introduced grasses, rock/brick piles and logs. The frogs utilise these features at different times of the year for breeding, foraging, shelter, moving or for protection over winter.


Identified threats to the Greenacre Key Population of Green and Golden Bell Frogs include:

  1. Loss of Habitat.
  2. Introduced predators that include:
    a. Plague Minnow – Gambusia holbrooki (Listed as a Key Threatening Process) present in Cox’s Creek and in many other water bodies and stream systems in the Upper Cooks River catchment.
    b. The Red Fox – Vulpes vulpes (listed as a Key Threatening Process for a number of threatened species). If you see any foxs’s please register them on Fox Scan.
    c. Feral and Domestic Cats – Felis catus
  3. Disease. Frog Chytrid is listed as a Key Threatening Process at state and national levels. This disease is rapidly emerging as possibly the single biggest threat to the species (as well as to many other species of frogs).
  4. Habitat degradation
  5. Water quality
  6. Small population size.
  7. Anthropogenic climate change (Listed as a Key Threatening Process).

How can you help?

Create frog friendly habitat in your garden or backyard. Avoid the use of fertilisers, herbicides and pesticides in areas where frogs may live. Learn more about native frogs including the Green and Golden Bell Frog by joining the Frog and Tadpole Study Group of NSW. Report sightings of the Green and Golden Bell Frog to your local Council.

How to report sightings to Council

To report sightings of Green and Golden Bell Frogs in the Strathfield local government area, please contact Council on 9748 9999 or email: Your sightings will contribute to the conservation of this endangered species.

To assist Council, where possible, please address the following questions in your report:

  1. Details about your sighting (eg did you see or hear the frog? was the frog alive or dead? what was it doing?)
  2. How many individual frogs did you see or hear?
  3. Location of sighting (where did you see the frog/s?)
  4. Date you saw or heard the frog?
  5. Description of the environment/habitat the frog was seen in (eg pond, long grass, rock pile, wood pile, in a shady area or an open area)
