The distinctive Eucalyptus tree is found in almost every Australian habitat.
The 915 species range from small ‘mallee’ shrubs, under a metre high, to the tallest hardwoods in the world, towering at over 100 metres.
The leaves of many species of Eucalyptus change in shape as they age. Some species have round young leaves which clasp the stem, but in maturity they become long and willowy.
The leaves produce aromatic oils to prevent them being eaten. This also means they readily catch alight. Many species are protected from fire by their outer bark while the heat actually encourages seeds to fall and germinate.
