Aboriginal people survived in arid inland by harnessing underground water pockets that are produced by mallee, one of the Eucalyptus species, that keeps water in their roots. Meanwhile, another species of Eucalyptus that grows well in swamps area marshes water massively from loose land. Italian is happy with that condition since the plant help them to dry Pontine swamp land that occupied by mosquitos. Nowadays this area becomes a valued farm land.
In Australia itself, as its homeland, Eucalyptus is designed to strongly survive from forest fire disaster. There is a non-active leaf buds exactly under its trunk and branch. This leaf buds starts to develop when the tree bark burnt due to fire. They cover tree bark that has already turned into black color because of fire with fresh green leaves. As a result, the core tree still survives after the fire disaster.
