Victoria is blessed with a wide diversity of native forest, dominated by eucalyptus (often known as gum trees). These forests contain many diverse habitats and include those found in the cool, mountainous, high rainfall areas in the east of the state, and in the Otways and Strzelecki Ranges near the coast. These wet forests are dominated by stands of alpine ash, messmate, shining gum and mountain ash (the tallest hardwood tree in the world). They remain the major source of high-quality seasoning timber for furniture, flooring, joinery and pulpwood. The dryer foothill forests contain mixtures of messmate and other commercial species, whereas the Murray River has extensive stands of durable red gum along its banks. Large tracts of mallee desert and box-ironbark woodlands are found in the drier northwest.
