The general objective of our study is to investigate the conservation activities of the Sitatunga(Tragelaphus spekii) for the sustainable maintenance of this species in the Sitatunga Valley Community Nature Park. To achieve our objectives, we used a methodology based essentially on participatory diagnostic tools, notably interviews, direct and participant observation, the Venn diagram, the SWOT (Strengths, Weaknesses, Opportunities and Threats) tool, triangulation and data analysis.At the end of our study, we understood that the Sitatunga(Tragelaphus spekii) is the most aquatic of antelopes, living in wetlands (marshes, swamps, ponds, pools, peat bogs). Sustainable conservation of this species will require the development of the Sitatunga Valley Community Nature Park. In fact, a program will be launched to create a specially protected wetland around this species, with the creation of a green belt around these areas. Ecological monitoring will also be carried out with the involvement of local communities, providing reliable data on the Sitatunga.
