Acacia Forests and Woodlands

• Trees are generally stunted (often less than 10m) but in some areas can grow to heights of 25m.
  
  
• Dominant species include Acacia shirleyi (Lancewood), A. catenulata (Bendee), A. aneura (Mulga), A. cambagei (Gidgee), A. harpophylla (Brigalow), A. papyrocarpa (Western Myall) and A. melanoxylon (Blackwood). The most widespread species are Mulga and Brigalow.
  
  
• Climatic conditions are generally dry, hot summers with cool to warm winters.

The mulga and brigalow communities of eastern Australia have been extensively cleared for grazing and agriculture. Mulga communities in the arid interior have not been cleared to the same degree. Many areas have been modified by the grazing of cattle/sheep and feral animals, and increased macropod populations supported by access to water from bores.
