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 Act and many of these are listed as Endangered Ecological Communities under the NSW Biodiversity Conservation Act 2016. These endangered ecological communities include Cooks River/Castlereagh Ironbark Forest, Sydney Turpentine Ironbark Forest and Coastal Saltmarsh. 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.
