Our Environment

As managers of the State road network we acknowledge our actions have the potential to cause negative impacts to Western Australia’s unique environment. We therefore have a responsibility to protect those environmental values that may be affected by our operations.

Our State is widely recognised as having unique flora and fauna species. This is demonstrated by the significant number of International Union for the Conservation of Nature (IUCN) Red List of Threatened Species located within the road reserve. The IUCN Red List of Threatened Species is recognised as a comprehensive inventory of the global conservation status of flora and fauna species. ​

We obtained the data for flora from the Western Australian Herbarium and the state Threatened Priority Flora records, which are maintained by the Department of Biodiversity, Conservation and Attractions (DBCA). We obtained data for fauna species from the state Threatened Fauna records maintained by DBCA.  Flora and fauna species of least concern that don’t have a conservation ranking have not been reported here.

Our road network also transects sensitive and protected environmental areas, such as:
