Description: The rangelands are those areas where the rainfall is too low or unreliable and the soils too poor to support regular cropping. They cover about 80% of Australia and include savannas, woodlands, shrublands, grasslands and wetlands. The rangeland boundary as defined by the Australian Collaborative Rangeland Information System (ACRIS) is based on mapped bioregions and, specifically, those largely undisturbed or natural bioregions (Interim Biogeographic Regionalisation for Australia, IBRA version 7.0) within Western Australia, South Australia, New South Wales, Queensland and the Northern Territory. The boundary in Queensland was modified according to some local government (i.e. shire) boundaries. The boundary was jointly defined by members of the ACRIS Management Committee and revised by the ACRIS Management Unit based on IBRA v7 mapping.
STAT7 is the ACRIS numbering of states based on IBRA7. STAT6 is the ACRIS numbering of states, based on IBRA6.1.
