The classification of a zone as an animal reserve or the extension of an area that is protected for tourism purposes, or protection of animals against illegal exploitation requires, as a preliminary, sufficient knowledge of the target area. One of the first stages in such a study is quantitative and qualitative inventory of the components of such an ecosystem. This study was undertaken in the Bomassa Triangle, a zone of approximately 45.000 hectares in the Department of Sangha, at the meeting point of Congo, the Central African Republic (RCA) and Cameroon. For eight (8) months, from February to September 2009, corresponding to the period of the dry seasons, an inventory of the large mammals was carried out by linear transects method in order to determine the abundance and distribution of species. The results showed that the Bomassa Triangle has a rich diversity of animals, including 13 species of large and average sized mammals.  The population and the density of the elephant as analyzed by the distance program showed that N = 167, 37 and D = 3, 73 observations/km². The information generated will help decision makers as they classify this zone into a community wildlife reserve.
