Notes
Habitat: It may be found near rivers, on established dunes and raised sandy plains of the deep Kalahari sands. Generally it is found in mixed open woodlands, and sometimes as dominant stands of large extent. Outside it's core area it appears only sporadically, or as a small isolated stand. Environment Latitude: It is found between 15-21°S. Altitude: It's core area is mainly in more upland areas, generally above 1200 metres, although it is found down to 200 metres. Temperature: It thrives with temperatures ranging from maybe -10ºC in winter to well over 38ºC in summer. -7° C may kill young plants. Reported temperature range for growth is 10-40°C with the optimum between 18-30°C. Water: It is a tree of seasonal drylands, surviving unreliable rains. Reported annual rainfall range for growth is 400-1000 mm with the optimum between 500-800 mm. Radiation Range & intensity: It thrives in full sunlight. Photoperiodism: Soil: Physical: It may be associated with alluvial soils near rivers, but most commonly with the deep Kalahari sands. It cannot tolerate areas subject to flooding. Chemical: It will not withstand saline soils. Estimated soil pH range for growth is 6-8.5 with the optimum between 6.5-8.
