Scientific name: Macadamia tetraphylla
Common names: Macadamia Nut, Queensland Nut, Poppel Nut, Prickly Macadamia, Rough-shelled Bush Nut and Rough-shelled Queensland Nut
Macadamia tetraphylla was the first Australian native food plant to be grown by non-indigenous Australians as a commercial crop. The first commercial plantation of macadamia trees were planted in the early 1880s 12 km southeast of Lismore, New South Wales. As the macadamia has spread worldwide in commercial agriculture, it is now listed as a vulnerable species in its native Australia due to habitat loss and degradation. The loss and impoverishment of its habitat has resulted from clearance of lowland rainforest for agriculture and urban development; invasive weeds; and poorly-designed fire management systems.
