The grassland tree fern, common name of Cyathea dregei, is found in reasonably moist conditions in many countries of southern Africa. It grows along rivers, in grassland and in rain forest areas. The local part of the natural distribution of this plant lies in the eastern and northern parts of South Africa.
This is a protected plant and must not be removed from the riverine kloofs where some good specimens still grace the land. In Australia the local tree fern common there, C. australis, seems robust in more arid conditions, growing in great numbers in Eucalyptus dominated forests.
There are more than 500 species of tree ferns worldwide, most of which occur in South America. Other species adorn Australian landscapes and some of the Pacific Ocean islands (Joffe, 2001; www.farngarten.de).
