Abstract

The aim of this study is to evaluate phytodiversity in urban environments. The new approach proposed in this work is based on the Saida conurbation. In order to assess the urban phytodiversity of the latter, the inventory and phytoecological diagnosis concerned 10 habitats (43 sites), for which we calculated an index (the Floristic Interest Index, FII), integrating information on the floristic richness index, naturalness (indigeneity) index, typicity index and rarity index of taxa. This new index identifies and classifies sites (sectors) and habitats of great interest for conservation and above all restoration, according to their degree of ecological importance. The results show that one suburban forest environment (fenced and more at the month monitored) had the habitat with high floristic interest index and two urban forest environments (open environment) had a medium floristic interest index. This is explained by the degree of impact of anthropic action and the presence of watercourses (riparian vegetation) for the first habitat.
