This is an alphabetical list of useful timber trees, indigenous and exotic, growing in the Gauteng area of South Africa. These trees range in size up to some 1.5m DBH, such as Cedrus deodara, the Himalayan Cedar. Hobbyists will seek out even small pieces of highly valued timber, such as Buxus macowanii, the South African counterpart of Buxus sempervirens, for turnery or the making of boxes and small items. Despite the wealth of useful woods available in Gauteng, most of the trees, felled or fallen, are dumped or cut into short lengths for fuel. Trees grown in urban or suburban environments are rarely pruned and are consequently often knotty. Timber frequently holds nails, wire and spikes, attesting to a variety of abuse during the lifetime of a tree, and requiring the use of a metal detector by the sawmiller. Garden cuttings and dead leaves are occasionally piled next to trees and burnt, leaving charred scars and inclusions.
