[4] The savanna woodland of the Borgu sector is dominated by Burkea africana, Terminalia avicennioides and Detarium microcarpum[citation needed].

Below the quartzite ridges Isoberlinia tomentosa predominates, and further down the hillsides on the relatively dry lower slopes are stands of Diospyros mespiliformis, with an understory of Polysphaeria orbuscula.

Terminalia macroptera occurs on moist savannas and Isoberlinia doka is found on higher ground in ironstone areas[citation needed].

In the Zugurma sector the tree cover is typical of the Guinean forest-savanna mosaic although this area is overgrazed and eroded, and the main woodland is besides the watercourses and waterholes.

Common trees here include Afzelia africana, Daniella oliveri, Pterocarpus erinaceus, Terminalia schimperiana, Parkia clappertoniana, Vitellaria paradoxa, Detarium microcarpum, Isoberlinia doka, Uapaca togoensis and Khaya senegalensis.
