The conservation and sustainable management of forest ecosystems necessarily involves estimating the animal populations that live there. For decades, several studies have been carried out in the Taï National Park (TNP) to provide information on the dynamics of animal species within this forest massif. This study falls within this framework and aims to estimate the abundance of Zebra duiker Gray, 1838 and Jentink’s duiker Thomas, 1892 according to their proportion of occupation of the sampling sites at the TNP. To achieve this objective, 285 camera traps were deployed, following a systemic setup. This work has made it possible to show that the zebra duiker in the TNP is found mainly in three parts (West, Center and South). As for the distribution of the Jentink’s duiker, it occupies almost the entire extent of the park. Regarding their abundance, the zebra duiker population is estimated at 232, between 138 and 390 individuals. While the population of Jentink’s duiker is estimated at 496 with a minimum of 305 and a maximum of 807 individuals at TNP.

In Ivory Coast, the decade of politico-military crisis has led to the degradation of national parks, After this crisis, knowledge of the wildlife diversity of these forests is needed to propose appropriate conservation measures. For this purpose, this study was conducted in the Mount Péko National Park (MPNP), located in western Ivory Coast. It aims to inventory the means and large mammals, to establish their spatial distributions and to determine their conservation status as well as the threats of human activities that weigh on them. The methodology used consisted first of all in surveys with the managers of the park and the local populations in order to have data on the fauna of the region. Pedestrian surveys inside the park were organized. At the end of this study, ten (10) species belonging to four (4) orders and six (6) species from (2) orders respectively of large and medium mammals were confirmed from direct and indirect observations. Most of these species occur in the surveyed areas except Cercopithecus campbelli, Civettictis civetta, Procavia capensis found only in the north and Syncerus caffer nanus observed only south of the park. Among the large mammal species, in addition to Loxodonta africana (VU), Pan troglodytes verus (EN) and Cephalophus sylvicultor (NT), all other species are listed in the category of Least Concerned (LC), according to IUCN. Similarly, apart from Phataginus tricuspis classified as Vulnerable (VU), all species of mammalian means are included in the LC category. However, the sustainable conservation of these mammals is threatened by various anthropogenic activities within the MPNP. In order to safeguard the biodiversity of the park, it is necessary to implement the management and management plan of the park, to involve all the stakeholders in the actions of monitoring, communication for a change of behavior and in real management MPNP. Scientific studies and ecological monitoring activities will need to be carried out to collect more comprehensive data as a tool to guide the sustainable management of MPNP.
