The Boé Sector covers 3,289 km2; in it, Boé National Park and Dulombi National Park are partly embedded  (Wit & Reintjes 1989). The Boé Sector is the most north-westerly part of the Fouta Djallon massive in Guinea (Conakry). The south eastern part of Dulombi National Park is the part of the Boé Sector west of the river Corubal, which can only be crossed by chimpanzees towards the end of the dry season.The landscape consists of flat plateaus with wooden Savanna vegetation (van der Meer 2014). Relatively narrow, shallow river valleys with often steep shorelines are found within this plateaus. Old secondary and often slightly disturbed forest is found further from the river channels (White & Edwards 2000). Along the rivers or streams, gallery forest and isolated savanna vegetation is growing. Here, under constant water supply, the greatest species diversity is found. Furthermore, the origin of the rivers are often designated as a sacred place by the people and thus have a low human activity (White & Edwards 2000, Silva et al. 2007, Koops et al. 2012, van der Meer 2014, Ramachandra 2017). Cultivated land, such as cashew tree plantations and cultivated fields of rice, peanuts, maize, sorghum, and millet are expanding steadily. The climate is tropical, with an annual mean temperature of 28°C and annual rainfall of c. 1,500-1,750 mm (USGS, n.d.). The Boé Sector is located in the tropical dry forest  climate zone. Daytime temperatures range between 30-33°C while nighttime temperatures vary from 18-23°C. It hardly ever rains from December to April and it is very wet from June through October. The area is sparsely populated, with around 12,000 people living in 85 villages, and still relatively well preserved. The region has contiguous habitats and it is considered to be a very important area for chimpanzees (''Pan troglodytes verus'') in West Africa (Van der Meer 2014).
