Introduction
Communities dominated by mulga (Acacia aneura F. Muell. Ex. Benth.--an N-fixing tree legume) occur extensively in Queensland, New South Wales, South Australia, Western Australia, and Northern Territory, occupying a total of about 150Mha or 20% of the continent (Johnson and Burrows 1994). In Queensland, mulga-dominated communities originally occupied 11.2 Mha, of which 12% has been cleared (Wilson et al. 2002). Between 1997 and 1999, mulga vegetation in Queensland was cleared at an annual rate of about 35 000 ha (Wilson et al. 2002), while the clearing rate for the Mulga Lands Bioregion as a whole was about 85 000 ha/year (Department of Natural ...
