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.

koala

オーストラリア東部・南東部を代表する有袋類で、体重は最大15kgに達し、低カロリーのユーカリの葉食から得るエネルギーを節約するために1日最大22時間を睡眠に費やす。他の哺乳類の多くを死に至らしめる有毒なユーカリ成分を処理するために高度に特化しており、解毒に特別に適応した腸内微生物叢を持つ。クラミジア感染症、生息地の伐採、気候変動により個体数が激減し、2022年に絶滅危惧種に指定された。
