| Abstract | African tropical forests and the primate communities they harbor are seriously threatened due to the accelerated rate of conversion, forest degradation and poaching. The impact of these threats is so great that some primate communities have been lost before being described or surveyed. Baseline data are therefore critical to understanding spatio-temporal variations of primates. Population estimates density or abundance are important variables to consider when determining conservation priorities and creating management plans for primate populations. As in forest ecosystems, the distribution and abundance of different tree species profoundly influence animal communities that live there, we first determined density and structure of trees species in Kibira forest. In 256 plots covering a surface area of 32.15 ha, a total of 6,504 stems distributed in 70 species, 67 genera and 37 families were recorded. Density was 202 stems per hectare, with a basal area of 21.05 m2 per hectare. A total of six species of diurnal primates were recorded including one species of great ape (Pan troglodytes schweinfurthii), four Cercopithecinae (Cercopithecus mitis, Cercopithecus mona denti, Cercopithecus lhoesti and Lophocebus albigena) and one Colobinae (Colobus angolensis). Density and total population are only known for chimpanzees, when only kilometric abundance index was calculated for the remaining species. This research has paid a particular attention to one emblematic species of the Kibira National Park, eastern chimpanzee, Pan troglodytes schweinfurthii. To protect better this subspecies endangered, we conducted investigations in nesting sites to identify species and characteristics of trees on which chimpanzees rely on for nests building. The results showed that chimpanzees select certain trees species for nests building. Mabayi sector, northern of the park, is the richest in primate species; it harbors five of the six species recorded, and two species: Cercopithecus lhoesti (Threatened) and Colobus angolensis are only found in Mabayi. This area of the park is a key to diversity and should therefore receive special attention in terms of protection and conservation.
