Diécké Forest Reserve is situated in the extreme south-east of Guinea, south of Nzérékoré and immediately north of the town of Diécké, close to the Liberian border. It is an area of lowland rainforest near the north-western limit of its distribution. Representative tree species include Parkia bicolor and Piptadeniastrum africanum. Although parts of the north-east of the reserve have been logged, much of the remainder is mature forest. The reserve also includes areas of swamp-forest dominated by Raphia palms, which makes access for commercial timber exploitation difficult or impossible in places. Annual rainfall is in the range 1,900–2,000 mm.
See Box and Tables 2 and 3 for key species. A total of 141 species is currently known from Diécké, a figure which suggests that many more have yet to be discovered. There are also earlier records of a number of additional species, including Scotopelia ussheri and Lamprotornis cupreocauda, from ‘Nzérékoré’, only a short distance to the north, which may therefore yet be found in Diécké.
