Roadside vegetation plays a very important role in maintaining the State’s biodiversity, particularly in agricultural regions. In some areas it is often the only remaining natural vegetation left in the landscape, providing valuable habitat and linkages between bush patches. Across the southwest, roadside vegetation contains rare flora, with over 50% of these species having at least one population on a roadside, and a number being dependent on the roadsides for their survival. Our State’s fauna also use roadside vegetation, either as part of their extended home range, or as their own highway to move throughout the landscape.
