A female hiker on the Overland Track in Cradle Mountain - Lake St. Clair National Park in central Tasmania. For a little over a week in late April (fall in Australia) the hardy, scraggly Fagus tree (deciduous beech) turns a fiery yellow, orange and red before dropping its leaves shortly after. The ancient variety, which grows only 2-3 meters high, is the only native deciduous tree in Tasmania. It is Australia's only cold climate winter tree to change color and lose its leaves each year. Found nowhere else in the world, they prefer to grow in the high, wet, 'inhospitable' environments of central and western Tasmania, such as the alpine mesas of Cradle Mountain - Lake St. Clair National Park pictured here. The scientific name, Nothofagus, stems from the Latin 'nothus', or false, and 'fagus' meaning beech. Nothofagus is one of the oldest genera of flowering plants in the world with a fossil record stretching back 80 million years. Sources: Parks &; Wildlife Service of Tasmania and ABC.
