Abstract. Surveys were carried out in the municipalities of Mecheria and Naâma (southwest Algeria) to identify the biodiversity of urban plantations and determine the ecosystem services related to these plantations. The results obtained enabled us to inventory 29 species belonging to 26 genera and 20 families, of which the Oleaceae family was the largest in terms of number of species. The only biological form identified was phanerophytes. Of the 29 taxa recorded, non-native taxa predominated (13 cultivated species, 4 introduced species, 4 naturalized/introduced species). Taxa of spontaneous origin number 7 and only one species is considered problematic. In terms of ecosystem services, we counted 5 shade species, 15 aesthetic species, and 9 food species.
