Coastal Paper-bark

Coastal paper-bark (Melaleuca halmaturorum) is a shrub or small tree in the family Myrtaceae, native to southern Australia, particularly South Australia and southwestern Victoria. It grows in coastal and inland saline environments, including salt marshes, samphire flats, brackish wetlands, and the margins of ephemeral lakes. The species is highly salt-tolerant, often forming dense thickets that provide critical habitat for waterbirds, including migratory shorebirds. Its distinctive bark peels in papery layers, a hallmark of the Melaleuca genus, while small white bottlebrush-like flowers attract native insects and honeyeaters. Reaching up to 5 metres in height, it can persist through seasonal flooding and drought cycles. Coastal paper-bark plays an important ecological role in stabilising saline soils, reducing erosion along shorelines, and filtering nutrients from adjacent agricultural land. The IUCN lists it as Least Concern, reflecting its wide distribution across southern Australia. It is also cultivated as an ornamental in gardens tolerant of poor drainage and is considered valuable for ecological restoration in degraded coastal wetlands.

호주 동부와 동남부의 상징적인 유대류로, 체중이 최대 15kg이며 저칼로리인 유칼립투스 잎 식단에서 에너지를 절약하기 위해 하루 최대 22시간을 잠으로 보낸다. 대부분의 다른 포유류를 죽일 수 있는 유독한 유칼립투스 성분을 처리하도록 고도로 특화되어, 해독에 특별히 적응된 장내 미생물총을 지닌다. 2022년 기후 변화, 서식지 개발, 클라미디아 감염으로 인한 개체수 감소로 위기종으로 지정되었다.
