Flora and Fauna of the Georges River Environment

Flora and Fauna analysis of key reserves and bushland areas provide a baseline inventory of species occurring within the Local Government Area (LGA) and identifies areas supporting biodiversity of high value and/or conservation significance. The results of surveys aid in the strategic planning and management of natural environmental assets and facilitate the future evaluation of changes in fauna diversity and responses of species due to management actions.

This information is used to indicate areas of high priority, threats to these areas, including climate change and urbanisation, and the effectiveness of current management practices.

This information can also assist in the development of planning and management for threatened species identified under the NSW Threatened Species Conservation Act (1995), and Environment Protection and Biodiversity Conservation Act (1999).

As the urban bushland within the Georges River LGA is fragmented and surrounded by heavily developed metropolitan areas, biodiversity is impacted by a large number of Key Threatening Processes (KTP).  The KTP’s are listed under the Threatened Species Conservation Act (1995), Environmental Protection and Biodiversity Act (1999) and Fisheries Management Act (1994):

Threatened Species Conservation Act (1995) Environmental Protection and Biodiversity Act (1999) Fisheries Management Act (1994)
Clearing of native vegetation Land Clearance -
Bushrock removal - -
Loss of hollow-bearing trees - -
Removal of dead wood and dead trees - -
High frequency fire resulting in the disruption of life cycle processes in plants and animals and loss of vegetation structure and composition - -
Anthropogenic climate change Loss of climatic habitat caused by anthropogenic emissions of greenhouse gases Human-caused climate change
Invasion and establishment of exotic vines and scramblers Novel biota and their impact on biodiversity -
Invasion, establishment and spread of Lantana camara Novel biota and their impact on biodiversity -
Invasion of native plant communities by exotic perennial grasses Novel biota and their impact on biodiversity -
Competition from Apis mellifera (Feral honey bees) Novel biota and their impact on biodiversity -
Predation by Gambusia holbrooki (Plague minnow or mosquito fish) Novel biota and their impact on biodiversity -
Predation by the Vulpes vulpes (European red fox) Predation by the Vulpes vulpes (European red fox) -


There are a large number of Key Threatening Processes relevant to the Georges River LGA, but not all of them operate at the same intensity in the same location. Council utilises Flora and Fauna Studies, and Site Plans of Management to identify the greatest threats to an area to prioritise and assist the protection of bushland environments, and the removal of relevant threats.
