Roads & the Environment

Our Aim

We are committed to protecting and enhancing the natural environmental and social values in all of our activities. All Main Roads staff and others working on Main Roads’ behalf will;

  • Recognise the importance of the natural environmental and social values and the broader benefits that these values provide to the community;
  • Foster strategic relationships with community and other stakeholders to contribute to the management of environmental values;
  • Facilitate environmental governance of our activities to deliver broad community benefit through the inclusion of environmental requirements in planning, programming, construction and maintenance processes; and
  • Communicate this policy and our environmental performance publicly.

 

Our Environment

As managers of the state road network, we acknowledge that our actions have the potential to cause negative environmental impacts to Western Australia's unique environment. We therefore have a responsibility to protect those environmental values that may be affected by our operations. Flora and fauna are two of our key environmental values and our State is widely recognised as having unique and special 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 that are 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.

​IUCN Classification *FloraFauna​Total ​

Data for flora was obtained from Western Australian Herbarium and Threatened Priority Flora records maintained by the Department of Parks and Wildlife (DPAW). Data for fauna species was obtained from the state Threatened Fauna records maintained by DPAW. Note that the majority of near threatened flora and fauna species are not recorded or reported and that none of the least concern (i.e. no ranking) flora and fauna species have been reported here. (GRI G4-EN14)

 

* The IUCN classification is based on the State and Commonwealth classification of flora and fauna:

​IUCN Red List Ranking

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

1. Wetlands of international importance (Ramsar Wetlands);

2. Threatened and priority ecological communities;

3. Department of Parks and Wildlife managed land and Environmentally Sensitive Areas;

4. Remnant areas of poorly represented native vegetation;

5. Bush Forever Sites;

6. Habitat for three protected black cockatoo species; Baudin’s Black Cockatoo, Carnaby’s Black Cockatoo and the Forest Red-tailed Black Cockatoo ; and

7. Areas of Native Title Claims and Determinations
