Abstract: In this 21st century, the world's attention is focused on the accelerated degradation of the biodiversity. This phenomenon of degradation seems to hasten the process of climate change and habitats that would amplify the lack of biological resources. The main objective of this work was to acquire scientific information on rodents and shrews biodiversity that colonize future Tshuapa-Lomami-Lualaba National Park. The study was conducted in the Congolese Central Cuvette precisely in Obenge village, in this national park the future Tshuapa-Lomami-Lualaba National Park. The trapping was carried out for 5 days, divided as follows: 2 days for traps installed in the secondary forest, 3 days for the traps installed in the village, its surroundings and in the fallow, 5 days for the traps installed in the primary forest. We combined Pitfall, Victor and Sherman traps to form devices to capture Rodents and Shrews. Specific richness, capture effort, trapping success, Shannon-Wiener alpha index and maximum equitability were the ecological indices used. We collected a total of 159 small mammals of which 110 rodents, 43 Soricidae and 6 macroselidae. From this study, CSB brought a new idea regarding the knowledge of rodent as well as shrew biodiversity in Tshuapa-Lomami-Lualaba future National Park and making available data for Natural Resource Managers for a sustainable development. These results show that body biomass of rodents’ ranges between 3 and 31g. The calculated biodiversity indices for different habitats show that rodent communities are less diversified. For the distribution of shrews sampled in different habitats, the most interesting was performed in primary forest at G dewevrei (42 out of 49 specimens where Crocidura sp. is the most captured with 16 out of 49 specimens). The body biomass ranges between 24 and 190g. The calculated indices of biodiversity for different habitats revealed that shrew communities are less diversified.
