Forest dominated by climax communities of trees that lose their leaves every autumn?

Trees that lose all their leaves once a year are called deciduous whereas trees which lose their leaves continuously and not all at once are called evergreen.

In temperate regions that experience cold winters, many tree species lose their leaves with the onset of the cooler weather in autumn (fall). These deciduous forests once covered large areas of temperate Asia, Europe and North America. Superb autumnal leaf colours can be seen in the deciduous forests of Canada and New England. They are not the only regions where deciduous trees are common however, and tree species in many sub-tropical and tropical regions which experience a strongly seasonal rainfall, also lose their leaves once a year with the onset of the dry season e.g. the African Acacia trees. Such trees are common in the savannas and woodlands of Africa, South America and Asia.
