The dynamics of the warthog (Phacochoerus africanus ) in the northern part of Senegal is very little known even though it is the only wild Suidae existing there. This study reported the density of warthogs populations in this Sahelian affinity local area and provide information about the age and sex groups. Linear transect of warthogs in the Djoudj National Park and the Gueumbeul Wildlife reserve confirms both the actual presence and density of the species in the Senegal River Delta. Estimating populations at the PNOD and RSFG gives IKA respectively of 2.1 and 11.3 individuals per km in 2014 and IKA 2.5 and 10.25 in 2015; IKC 0.93 and 2.4 contacts per km in 2014 and IKC 2.5 and 1.29 in 2015 to densities of 12.05 and 36.10 individuals per km² in 2014 and 13.03 33.33 individuals per km² in 2015. The predominance of older than 3 years is the most represented while younger than 1 year are the least represented. In both study sites, the sex-ratio is biased in favor of females.
