Coastal Box

Eucalyptus quadrangulata, the coastal box, is a medium-sized eucalyptus tree in the family Myrtaceae native to the coast and ranges of eastern Australia, from southeastern Queensland through New South Wales to northeastern Victoria. The species grows in dry sclerophyll forest, woodland, and coastal heathland on a variety of substrates from sandy coastal soils to shallow clay soils on rocky outcrops. It reaches 12–25 meters in height and is characterized by persistent, hard, rough grey box-type bark covering the trunk and major branches, with smooth white to grey bark on the upper branches and smaller limbs. Cream-coloured flowers are produced in clusters that attract honeyeaters, lorikeets, and a range of insect pollinators. Eucalyptus quadrangulata is classified as Least Concern by the IUCN, being moderately widespread along the eastern Australian coast, though coastal development, land clearing, and altered fire management have reduced the extent and connectivity of its habitat in some areas. The hard timber has historically been used for fence posts, railway sleepers, and construction, valued for its durability and density. It provides important habitat for hollow-dependent fauna including possums, gliders, owls, and parrots in eastern Australian forest ecosystems.
