Ouilingoré

Ouilingoré Classified Forest (Forêt Classée d'Ouilingoré) is a protected woodland area of approximately 68.5 square kilometers (6,850 hectares) in Boulgou Province within the Centre-Est region of Burkina Faso, situated roughly 30 kilometers from the regional center of Tenkodogo.^[1] The forest preserves Sudanian savanna vegetation in a region characterized by the transition between the Mossi Plateau and the eastern lowlands. The forest provides essential ecosystem services to surrounding agricultural communities, including soil stabilization, watershed protection, and a regulated supply of forest products. In a region where woodland has been extensively converted to farmland, classified forests like Ouilingoré serve as critical refugia for biodiversity and as buffers against environmental degradation.

Ouilingoré supports a savanna wildlife community adapted to the woodland-farmland mosaic of the Centre-Est region. Small to medium mammals including duikers, hares, and various rodent species are likely present, along with baboons and patas monkeys. The birdlife is typical of the Sudanian zone, with species including various hornbills, barbets, and sunbirds in woodland areas, and bustards and coursers in more open habitats. Raptors including brown snake-eagle patrol the forest margins. Reptiles and amphibians are present in seasonal watercourses and rock outcrops within the forest.

The forest vegetation reflects the Sudanian woodland zone with a canopy of Vitellaria paradoxa (karité), Parkia biglobosa (néré), Combretum glutinosum, and Terminalia species.^[2] The woodland structure is moderately open, with a well-developed grass layer of perennial Andropogon and Hyparrhenia species. Deciduous shrubs including Guiera senegalensis and Piliostigma reticulatum form the understory. Gallery forest strips along seasonal drainage lines support taller, moister vegetation. The forest's plant community includes numerous species valued for traditional medicine, food, and craft materials.

The Centre-Est region lies on the Precambrian basement complex, with Ouilingoré situated on a gently undulating landscape of granites and gneisses overlain by laterite and weathered regolith.^[3] Low granite inselbergs may be present in or near the forest, providing distinctive microhabitats. The laterite surface is incised by seasonal drainage channels that collect runoff during the rains. Soils range from thin, gravelly laterites on exposed surfaces to deeper, more productive soils in valley floors. The geological stability of the region means that the landscape has been shaped primarily by weathering and erosion over very long timescales, producing the characteristic reddish ferruginous soils of the Sudanian zone.

Ouilingoré experiences a Sudanian climate with annual rainfall of approximately 750 to 900 millimeters, concentrated in the June-to-September wet season. The dry season from November to May is long and hot, with temperatures exceeding 40 degrees Celsius in March and April. Harmattan conditions prevail from December to February, with dry, dust-laden winds from the Sahara reducing humidity and visibility. The rainfall is broadly adequate for Sudanian woodland but less reliable than in western Burkina Faso, making the vegetation somewhat more drought-stressed than forests in higher-rainfall areas.

The Centre-Est region is populated primarily by Mossi and Bissa peoples, with agricultural economies based on millet, sorghum, and groundnuts.^[4] The dense Mossi population has resulted in intensive land use over centuries, with much of the original woodland converted to farmland. Traditional agroforestry practices that preserve useful trees such as karité (Vitellaria paradoxa) and néré (Parkia biglobosa) within cultivated fields have helped maintain some tree cover outside classified forests. The region has experienced significant out-migration to Côte d'Ivoire and other destinations, though returning migrants and population growth continue to drive demand for agricultural land. The Boulgou Province in which the forest lies has its administrative center at Tenkodogo.

Ouilingoré was classified as a protected forest by the French colonial administration of Upper Volta as part of the systematic establishment of forest reserves across French West Africa during the colonial period.^[2] The classification has been maintained through independence and successive governance changes, though enforcement has been limited by the intense pressure from surrounding agricultural communities. Management has relied on a combination of boundary patrols, community engagement, and periodic investments in reforestation. The classified forest represents one of the few remaining significant woodland areas in a region where natural vegetation has been extensively converted to agriculture.

Ouilingoré Classified Forest has no formal tourism facilities or developed trails. The forest offers an accessible example of Sudanian woodland ecology for visitors traveling through the Centre-Est region. Birdwatching is possible, though the proximity to farms means that wildlife is generally more wary than in remote reserves. The forest provides a green contrast to the surrounding farmed landscape, particularly after the rains when the woodland canopy is at its fullest. The Centre-Est region is, like much of Burkina Faso, affected by the ongoing security crisis; Burkina Faso is under a Level 4 (Do Not Travel) advisory from most Western governments, and the Centre-Est has experienced jihadist activity — travelers should consult current government advisories.

Access to Ouilingoré is from the main road connecting Ouagadougou to Tenkodogo and the eastern region; the town of Tenkodogo is approximately 30 kilometers away. There are no visitor facilities within the forest. Basic accommodation is available in Tenkodogo. The dry season from November to March is most suitable for road access, though the landscape is greener and more attractive from July to October. Permission should be sought from local forestry authorities before entering the classified forest. Visitors should carry water and be prepared for basic conditions. Due to ongoing insecurity in the Centre-Est region, travel should only be undertaken after checking current security advisories.

Ouilingoré faces severe conservation pressure from agricultural expansion, fuelwood collection, charcoal production, and livestock grazing. The dense surrounding population creates high demand for forest resources that exceeds sustainable yield. Conservation strategies focus on community engagement, the development of woodlots and agroforestry to reduce pressure on the classified forest, and the enforcement of boundaries against encroachment.^[2] Climate change is expected to reduce rainfall reliability in the Sahel, adding to the stress on forest ecosystems. The long-term survival of the forest depends on reducing direct extraction pressure and improving the ecological condition of surrounding farmed landscapes.
