F.Muell. ex Benth.Acacia harpophylla, commonly known as the Brigalow , Brigalow Spearwood or Orkor is an endemic tree of Australia. It is found in central and coastal Queensland to northern New South Wales. It can reach up to 25 meters tall and forms extensive open-forest communities on clay soils.
Two species, brigalow (A. harpophylla) and gidgee (A. cambagei) form open woodlands on flat and gently undulating terrain on heavy and relatively fertile clay and clay-loam soils primarily in the 300-700mm annual rainfall region of Eastern Australia. These woodlands extend from a northern extreme of 20o S into northern New South Wales. Brigalow and gidgee occur as mixed communities in some regions and are commonly associated with several other woody species, including overstorey species such as Eucalyptus coolabah, E. cambageana, Casuarina cristata, and a range of understorey species.[1][2] Chloris, Paspalidium, Dicanthium, Sporobolus and Eragrostis species.[7]
