8. Bring in nature


A living river also needs grasses, shrubs, trees and animals such as fish and birds to be a complete ecosystem. By maintaining and improving habitats for our iconic species, especially our five mascots, we can bring nature back to the river. Doing so means understanding current habitat health, establishing foreshore improvement programs and calling on citizen science to help track progress.

The diverse natural environment of the Parramatta River catchment can be categorised into four broad ecosystems that support the habitat of our five mascot species:

  • Terrestrial – the land areas across the catchment; habitats include forests, woodlands and bushland pockets.
  • Riparian – the riparian zone is the transition zone from terrestrial to river; habitats include river and creek banks and floodplains.
  • Freshwater – the tidal impact is limited by the weirs, upstream the Parramatta River system is fresh water; habitats include the numerous small creeks and tributaries across the catchment that flow into the river.
  • Estuarine – the Parramatta River is tidal below Charles St Weir at Parramatta. Habitats include saltmarsh, wetlands, mudflats, mangroves and bays, and the upper harbour itself.

Species were selected as potentially iconic expressions of these natural systems and the ecological benefits they provide to people living in the catchment. Following a desktop review of local community groups and threatened species records, 19 species were shortlisted and put up for public vote. The following five animals were chosen as our iconic mascots:

  • Bar-tailed Godwit
  • Eastern Long-necked Turtle
  • Powerful Owl
  • Southern Myotis
  • Striped Marsh Frog

Maintain, improve and create new habitats for the Parramatta River catchment’s five iconic species mascots as indicators of water quality and catchment health.

Status Update

  • Develop and promote Citizen Science app for all Parramatta River iconic species.
  • Map the presence of hollow bearing trees in the catchment.
  • Encourage strategic installation of manmade hollows.
  • Work with Councils, agencies and community to identify areas to provide dense riparian vegetation.
  • Map current wetlands.
  • Work with councils, agencies and the community to identify areas suitable for new offline wetlands.
  • Identify opportunities for signage and education materials to protect mudflats and Bar-tailed Godwits habitat.
