​Biodiversity or biological diversity is the variety of all species on earth. lt is the different plants, animals and mícro-organisms, their genes, and the terrestrial, marine and freshwater ecosystems of which they are part. (Australian Government Department of Environment)

Biodiversity is essential; it provides the elements necessary to create a healthy and productive environment.

The main threats to our biodiversity are:

  • loss, fragmentation and degradation of habitat
  • the spread of invasive species
  • unsustainable use of natural resources
  • climate change
  • inappropriate fire regimes
  • changes to the aquatic environment and water flows

Protecting and enhancing biodiversity is vital for our survival; humans rely on living organisms and
systems for our food, materials and energy.
Auburn City Council retains only a small percentage of 'natural areas', what we do have however is extremely important. A number of our vegetation communities are lísted under the NSW Threatened Species Conservation Act 1995 as Endangered Ecological Communities (EECs) and these include:
  • Sydney Coastal Freshwater Wetlands EEC
  •  Cumberland Riverflat Forest EEC
  •  Cumberland Swamp Oak Riparian Forest EEC

Auburn local government area is home to Sydney Olympic Park which contains species and ecological communities that were once widespread in Sydney but are now uncommon in urban areas. These are of conservation significance at a local, regional, state, national or international level.  Sydney Olympic Park Authority manages the public assets of Sydney Olympic Park.
Rockwood Necropolis is the largest necropolis in the southern hemisphere; it is located within Auburn local government area and is managed by a number of Trusts on behalf of the NSW State Government.  The necropolis covers an area of over 300 hectares, it provides valuable habitat within the otherwise highly urbanised environment and contains remnant patches of indigenous flora.
