Eucalypts (Gum Trees)

Their range extends from sub-alpine areas to wet coastal forests, temperate woodlands and the arid inland. In fact, the only major environment where eucalypts are absent is probably rainforest.

Eucalypts are a defining feature of Australia. They are the dominant tree of the developed areas of the country, although only sparsely represented in the driest regions. There are over 800 species which have adapted to nearly every environment.

Eucalypts come in a great range of shapes and sizes – from tall trees to small shrubs. Eucalypts are a dominant part of the Australian flora. Eucalypts range across Australia – the only landscape they are completely absent from is the high alpine areas, though they are scarce in rainforests and in the arid interior of the continent, except where they find refuge along streams and in isolated ranges.

Eucalypts serve as shelter for many species of native Australian animals and birds. A few varieties of gum leaves are the only food eaten by koalas.

The eucalypt is extremely adaptable. Within species there can be physical adaptations to factors such as soil aspect and proximity to water. For example, E. pseudoglobulus (Gippsland Bluegum) grows 30–40m tall in inland forests and yet it can adapt to exposed coastal cliffs by growing mallee-like (with multiple trunks) and small in height.

Eucalypts, evolved to cope with Australia's climate, have adapted to survive though drought and bushfire.

Most eucalypts can regenerate from seed after fire. Many eucalypts have woody capsules that protect the seeds during fire, but which open after fire, releasing their seeds.

Koalas naturally inhabit a range of temperate, sub-tropical and tropical forest, woodland and semi-arid communities dominated by Eucalyptus species. Koala habitat can be broadly defined as any forest or woodland containing species that are known Koala food trees. The distribution of this habitat is largely influenced by land elevation, annual temperature and rainfall patterns, soil types and the resultant soil moisture availability and fertility. READ MORE

Northern Quoll

The Northern Quoll occupies a range of habitats including rocky areas, eucalypt forest and woodlands, rainforests, sandy lowlands and beaches, shrubland, grasslands and desert. Their habitat generally has rocky areas for dens. Dens are made in rock crevices, tree holes or occasionally termite mounds. Northern Quolls appear to be most abundant in habitats within 150km of the coast. READ MORE

Glossy Black-cockatoo

The Glossy Black-Cockatoo (Kangaroo Island) is currently restricted to Kangaroo Island in South Australia. The last accepted record of the Glossy Black-Cockatoo (Kangaroo Island) from mainland South Australia was reported in 1977. The extent of occurrence of the Glossy Black-Cockatoo (Kangaroo Island) is estimated, with high reliability, to be 4400 km². The extent of occurrence is considered to be stable at present, but it has declined in size since the arrival of European settlers. The Glossy Black-Cockatoo formerly occurred on both Kangaroo Island and mainland South Australia. READ MORE
