Which eucalyptus do koalas eat

For instance, koalas in Victoria eat the leaves of different gum trees from those eaten by koalas in Queensland. Like pasture for sheep, a forest can only support a limited number of koalas because the available gumleaves can only feed a certain number of koalas. If there are too few trees in an area of forest, for instance, if some of the forest has been cleared for housing or other development, the koalas may eat more leaves than the trees can regenerate re-grow and the trees may die.

Then the koalas may get sick or die, too. When the forest is in balance, this does not happen, but when the forest and the surrounding land has been damaged by clearing, logging or pollution, the animals which live in that forest will suffer, too. In most cases, we humans are responsible for damaging and changing many fragile ecosystems on earth, some of which support koalas.

Eucalyptus leaves are very fibrous and low in nutrition, and to most animals are extremely poisonous. To cope with such a diet, nature has equipped Koalas with specialised adaptations. Eucalyptus grandis Flooded gum, Rose gum.

This attractive, tall, straight trunked tree grow to over 30 metres. The bark is smooth white to grey in colour. The leaves are glossy dark green. Eucalyptus major Grey Gum. This medium sized tree grows to a height of 30m. It's slightly granular and corky to the touch.

The leaves are dark green above and paler below. Eucalyptus moluccana Gum Topped Box. This is a medium sized to tall tree with rough, persistent bark on the lower trunk, shedding above to leave a smooth whitish or light grey, sometimes shiny surface. The branches are smooth, the bark sheds annually in long strands. The adult leaves are stalked, broad, lance shaped, glossy green with numerous oil glands.

Eucalyptus pilularis Blackbutt. This is a medium-sized to tall forest tree. It is identified by a covering of rough bark, to about half way up the trunk. Above this is white smooth bark. The common name refers to the black base of the tree after fires. The leaves are wide and glossy, green to dark green. Eucalyptus racemosa Scribbly Gum. This is a small to medium sized tree grows up to 30 metres tall. The bark is smooth with shedding bark of white, grey or yellow.

Scribbles, caused by moth larvae, are often found on the bark and the leaves are grayish green on both sides. When the bark sheds in short ribbons it is white, grey or yellow in colour. Eucalyptus resinifera - "resin bearing" Red stringy bark. This grows to around 45 metres. The bark is rough, stringy and fibrous. The relatively sedentary and localised movements of Koalas in a socially stable breeding aggregation are in stark contrast to the movements of dispersing Koalas of both sexes those leaving their maternal home range to establish a home range of their own and other transient members of Koala society.

These animals are capable of extensive movements, often in excess of km over periods of a few weeks to several months. Breeding activity on the part of the mother usually initiates the dispersal phase of the young from her previous breeding season. The movements and survivorship of these dispersing animals are significant because they contribute to maintaining recruitment levels and genetic vigour in breeding aggregations that are separate from one another.

Indeed, it is not so much the presence of preferred food trees that influences the movements of these animals as it is their need to be with other Koalas. In this regard, established aggregations attract dispersing animals from other aggregations. Koala Habitat Atlas studies have been undertaken in portions of the following areas and the most preferred species are listed.

This project aims to identify any potential Koala habitat in Australia that as yet, does not have a Koala Habitat Atlas project. As with all mapping, it is subject to refinement as land is cleared or trees grow. The landscape continually changes. The work being undertaken by the Australian Koala Foundation with its Koala Habitat Atlas Project is looking very closely at tree use by Koalas in specific areas and is confirming that tree species preferences often vary on a local or regional basis.

The tree list incorporates the most significant Koala use trees from the areas investigated by the AKF to date as well as drawing upon other published species lists.
