Dry foothill forest; montane dry woodland; grassland; plains grassy woodland; valley grassy forest; coastal grassy woodland; herb-rich woodland; montane grassy woodland; riverine grassy woodland; rainshadow woodland; boinka-raak; mallee woodland; heathy woodland; wimmera mallee/woodland; lowland forest; box-ironbark forest; inland slopes and sedge-rich woodland.

Colours indicate possibility of Centaurea solstitialis infesting these areas.
Red = Very High
Orange = High

In the non-coloured areas the plant is unlikely to establish as the climate, soil or landuse is not presently suitable.
