Rapid and uncontrolled urbanization due to population growth in the city of Korhogo is creating socio-economic and environmental problems. Urban and peri-urban trees (AUP) play an important role in improving this situation. But this knowledge is very limited. Therefore, this research would like to show the types and role of AUPs based on the Millennium Ecosystem Assessment (MEA) services. Triangulation of methods (analysis of secondary data from the literature review and primary data from surveys and field observation) was used to highlight the types of trees that are predominantly present in the city of Korhogo and their role in the lives of 240 city dwellers. The results showed that (i) there are 44 species, divided into 23 families of which 10 families are dominant. The mango tree (Mangifera indica) is dominant with 80% and the other 20% represent exotic trees such as neem (Azadirachta indica), Acacias Auriculiformis, Eucalyptus, etc. (ii) The role of the trees is derived from those of the MAE services which are: Provisioning (fruits, leaves, wood, food, source of economic income, medicine, with the economic function); Regulating (especially the Provision of shade, recreation, well-being and health, carbon sequestration, oxygenation, microclimate, with the ecological function); Supporting (soil erosion control, maintenance of biodiversity, provision of organic matter, with the ecological function) and Cultural (meditation, education, respect us and custom, spiritual, aesthetic, with the social and cultural function). A sustainable management of all AUP is necessary in the city of Korhogo.
