Great Western Woodlands

The Great Western Woodlands is located in the southwest of Australia. The woodlands cover almost 16,000,000 hectares, a region larger in size than England and Wales. The boundary of the Great Western Woodlands runs from the Nullarbor Plain in the east to the Western Australian Wheatbelt in the west; from north of Esperance through to the inland mulga country and deserts that are found north of Kalgoorlie.The boundaries of this region were established by researchers from the Australian National University working with The Wilderness Society and are based on satellite data of the region's natural ecosystems and vegetation types.
