Abstract: This study examined soil properties, regeneration biology and vegetation associates of the 3 subspecies of Sclerocarya namely; birrea, caffra and multifoliolata in Tanzania. The plotless sampling technique was used to obtain 100 mature trees, 1 from an on-farm and another from a wild environmental setting; for each of the 3 subspecies. A total of 600 mature trees were sampled and 40 soil samples were collected for analysis both of the 2 settings (on-farm and wild environment). Seedlings and saplings, as well as species associates were also inventoried. Results show that most of the basic soil properties were not influenced by the subspecies, although a more robust soil sampling is suggested. Most populations originated from coppicing and sprouting than from seed sources. Interestingly, there was no single species associate associated with all the 3 Sclerocarya subspecies but associates of 2 subspecies were found.
