In Algiers, there is no environment that can be described as natural. The objective of this work is to evaluate floristic diversity in cities.This approach is conducted on a scale of the agglomeration of Algiers (Northern Algeria). In order to study the urban biodiversity of the latter, the inventory involved 36 sites spread over 11 habitats and for which we calculated a new index, namely the Floristic Interest Index (IFI), including information on the richness, indigenate, typicity and rarity of the species. This index makes it possible to identify sites and habitats of great interest for conservation. 420 vascular species were identified of which 367 indigenous (87.3%) against 53 naturalized (12.6%), representing 75 families with a predominance of the Asteraceae family with 57 species. Biological types are predominantly therophytic with 42.2%, there is also a high proportion of Mediterranean species in terms of biogeographic origin. Forest environments (urban and suburban) are high IFI habitats this is explained by moderate human activity weakly impacting these spaces. Multivariate analyses identified three groups differentiated by the degree of anthropization, combined with other ecological factors acting simultaneously. This study shows an unsuspected biodiversity in these urbanized environments that can play an important role in urban green frameworks.
