Acacia Open Woodlands

• Usually occur in low to undulating inland areas, in regions with mainly summer rainfall in northern Australia, and mainly winter rainfall in southern Australia.
  
  
• Cover extensive areas of the arid zone and drier tropical north, mostly with a shrubby or grassy ground layer.
  
  
• Dominant acacias include Acacia aneura (Mulga), A. georginae (Georgina Gidgee), A. tephrina (Boree), A. cambagei (Gidgee), A. harpophylla (Brigalow), A. peuce (Waddy) and A. papyrocarpa (Western Myall), with the most widespread species being Mulga.
  
  
• Ground layers are generally herbaceous or chenopod/saltbush shrubs and grasses.

Little of the Acacia Open Woodlands have been cleared. Many areas have been modified by grazing pressure from domestic stock, feral animals and macropods.
