Eucalyptus crebra, commonly known as the narrow-leaved ironbark or narrowleaf red ironbark, is a type of Ironbark tree native to eastern Australia.A member of the large genus Eucalyptus, this tree is in the Myrtaceae family and can grow to a large spreading tree up to 35 m (100 ft) high. Suitable for: light (sandy), medium (loamy) and heavy (clay) soils. The tree's name ironbark stems from the rough and unyielding texture of the cambium on the outmost layer of the plant. fibrosa and E. exserta. Density approx. Context Hollow-bearing trees are an important breeding and shelter resource for wildlife in Australian native forests and hollow availability can influence species abundance and diversity in forest ecosystems. Large scale plantations have been raised in government owned and private farm lands; the planting is continuing. The koala population in Australia is estimated at 80,000, but before the arrival of the aboriginal people, their population ranged into millions.

In the early days of colonization wood felling was achieved with axe and saw, ironbark stands usually meant a broken ax head. decline as tree density increases (Walker et al. Eucalyptus in India - R.M. Conservator of Forests, Kanara Circle, Karnataka. 1986a), to an initial increase at low canopy cover followed by a decrease as cover increases further (Scifres et al. Lophostemon confertus (tree form and whipstick form) often present in gullies and as a sub-canopy or understorey tree. We sampled 47 sites stratified according to vegetation type (Eucalyptus crebra/Eucalyptus dealbata woodland; Eucalyptus melliodora/Eucalyptus microcarpa grassy woodland), density of mature trees (<6 trees/ha; 6–20 trees/ha; >20 trees/ha), and presence/absence of regrowth. Eucalyptus leaves consist of approximately 13% tannins, 2% minerals, 50% water, 18% fiber, 8% fat, 5% carbohydrates and 4% proteins.Sometimes, they also feed on the bark, buds and flowers of the eucalyptus trees.
