Allocasuarina huegeliana
Also called Rock Sheoak, Rock Sheoak Or Sighing Sheoak
Allocasuarina huegeliana, commonly known as rock sheoak is a species of flowering plant in the family Casuarinaceae and is endemic to Western Australia. It is a dioecious tree that has its leaves reduced to scales in whorls of eight to ten, the mature fruiting cones 14–35 mm (0.55–1.38 in) long containing winged seeds (samaras) 5–7 mm (0.20–0.28 in) long.
A. huegeliana is a moderate to fast growing tree that is nitrogen fixing. It can be grown as a windbreak. The species thrives in well-drained soils but will do poorly in saline or poorly drained areas. The attractive and dense wood from the tree is used to make specialty furniture while the foliage is used by grazing stock as fodder. The species is drought and frost tolerant but will be killed by fire. Trees can live up an age of over 15 years.
Rock sheoak grows near granite in the south-west of Western Australia, where it in native in parts of its range, but naturalised in other places. It occurs from the Murchison River and Mingenew, south to the south coast, and east to near Balladonia, in the Avon Wheatbelt, Coolgardie, Esperance Plains, Geraldton Sandplains, Jarrah Forest, Mallee, Murchison and Swan Coastal Plain bioregions of Western Australia.
