Guinea harbors the largest remaining population of western chimpanzees (''Pan troglodytes verus''). Sugiyama and Soumah conducted the first nationwide survey in Guinea by sending questionnaires to officers of the provincial governments, and concluded that only a few thousand chimpanzees remain (1988). A follow-up survey based on questionnaire, reconnaissance and transect surveys concluded that the chimpanzee population in Guinea was much larger with up to 23,000 individuals (Ham 1998). More recently the [http://www.wildchimps.org  Wild Chimpanzee Foundation] conducted transect surveys as 10 sites including a large-scale systematic survey across the Fouta Djallon Bafing Area and estimated that at least 18,000 western chimpanzees remain (WCF 2012). Based on the modelled density distribution of western chimpanzees across their geographic range Heinicke et al. (2019) estimated 33,139 (CI: 8,796-68,203) individuals in Guinea, with highest population densities in the Fouta Djallon (Heinicke et al. 2019, WCF 2012).
