Excerpt from Forestry and Forest Industry in South Africa

From "Description of the Plantations" "Species"
The species used for afforestation in South Africa belong almost entirely to three genera: Pinus, Eucalyptus and Acacia. The eucalypts and the acacias were brought to this country from Australia, while the pines came from southern Europe (P. pinaster), Mexico (P. patula), California (P. radiata), the Southern States of the U.S.A. (P. elliottii and P. taeda), Central America (P. caribaea), the Canary Islands (P. canariensis) and northern India (P. roxburghii).
The most suitable species for the temperate summer-rainfall area (zones G and K in Fig.3) are P. patula, P. elliottii, P. taeda, Populus deltoides (probably of the variety missouriensis), Eucalyptus saligna, E. grandis and Acacia mearnsii (wattle). The two last-mentioned species should be limited to areas where severe frost is not encountered. Suitable species for the sub-tropical (summer-rainfall) zone ("N" in Fig.3), i.e. mainly the coastal strip from Transkei in the south to Zululand in the north, are P. caribaea, P. elliottii, Eucalyptus grandis, E. paniculata, E. cloeziana, E. maculata, E. microcorys, E. citriodora and Populus deltoides var. missouriensis.
In the constant rainfall area of the Cape Midlands Pinus radiata, P. pinaster, P. elliottii, P. taeda, Eucalyptus diversicolor and Acacia melanoxylon are the main species used, while in the winter-rainfall area of the Western Cape, finally, the most important species are Pinus radiata, P. pinaster, P. canariensis and Eucalyptus cladocalyx. All these species will be further dealt with in the next chapter."
