Diéfoula and Logoniégué are contiguous Classified Forests situated in the south-west of Burkina, along the border with Côte d’Ivoire. The southerly flowing Comoé river separates Diéfoula, to the west, from Logoniégué, until its confluence with the Léraba river, where it turns south-east to mark the southern edge of Logoniégué and become the international frontier. The Léraba river forms the southern boundary of Diéfoula and also marks the international frontier. Except for a number of sedimentary plateaus, which rise above the surrounding plain, the terrain slopes gently southwards from a maximum altitude of about 450 m. In places, erosion gullies have formed at the bottom slopes. The main drainage channels are shallow, gently sloping and form open flood-plains as they approach the rivers. The vegetation is characterized by semi-deciduous gallery forests up to 30–40 m high, dry forests of 15–20 m and open, park-like savanna woodlands. The dominant tree species are Daniellia olivieri, Isoberlinia doka, Pterocarpus erinaceus and Khaya senegalensis. The site is the amongst the wettest in Burkina, with an annual average rainfall of c.1,300 mm. The site lies a little to the north-west of Comoé National Park in Côte d’Ivoire (IBA CI001).
See Box and Table 2 for key species. The avifauna is, as yet, poorly known and it is likely that more species characteristic of the Sudan–Guinea Savanna biome will be found to occur. Among those that have been recorded is Apaloderma narina.
Non-bird biodiversity: Mammals of global conservation concern include Colobus polykomos (LR/nt), Loxodonta africana (EN) and Cephalopus sylvicultor (LR/nt). This is the only locality in Burkina from which the colobus and the duiker are known.
