Trees and shrubs are essential components in the production of ecosystem services. The aim of this study is to evaluate the biodiversity of plantations in arid regions. A floristic inventory was carried out in three biotopes using an exhaustive sampling approach. Diversity parameters were calculated to assess phytodiversity in each biotope. A total of 23 plants species belonging to 17 families, with a dominance of eudicots at 95.65% were recorded. The dominant families were Fabaceae (17.38%), Arecaceae, Lythraceae and Tamaricaceae (8.69%). The flora was mixed with 56.52% of exotic plant species. The most predominant plant species were Phoenix dactylifera L, Tamarix aphylla (L.) H. Karst, Dodonaea viscosa (L.) Jacq, and Leucaena leucocephala (Lam.) de Wit, these species accounted for 72.74% of all individuals inventoried. Shannon’s diversity index and Piélou index of evenness range from 2.68 to 2.95 bits and 0.64 to 0.69, respectively. Simpson’s index range from 0.78 to 0.82. Hamming distance range from 21 to 43. Plantations provide ecosystem services with great importance on ornamental interest. The data collected in this study should be used for creating a floristic database. This database will be regularly updated for monitoring urban plantations. The information resulting from the monitoring will help to improve the urban forest management projects in the development plan.
