Allocasuarina luehmannii (buloke or bull-oak) is a species of ironwood tree native to Australia. The species occurs across a vast region of eastern and southern Australia, mainly north and west of the Great Dividing Range and within the Murray-Darling Basin. Its extent of occurrence has been greatly depleted by clearing for cereal cropping and pasture development. It is an important food resource for the endangered southeastern subspecies of the red-tailed black cockatoo in the Wimmera region of western Victoria, where some remnant stands are threatened by farming practices [1]
The Shire of Buloke in Victoria, Australia is named after this tree species.[2]
It is known as having the hardest wood in the world, with a Janka Hardness of 5060 lbf.[3]
