The ironbark woodlands have a relatively open canopy of trees, a sparse cover of shrubs and a dense sward of grasses. The tree has a hard, strong, and dark red timber, which has been used for sleepers and construction. Trees have a dense canopy. Such a large population would have a significant impact on the canopy density and the amount of light reaching the forest floor. 1986a), to an initial increase at low canopy cover followed by a decrease as cover increases further (Scifres et al. 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.
