Floristic composition of the halophilic and salt-resistant plant population in Hammam-Boughrara (Oran-Algeria)

Abstract

This phyto-ecological study is on halophilic and salt-resistant vegetation of Oran region. The semi- arid and sometimes arid climate has been defined and confirmed from a bioclimatic point of view. The pedological approach used shows a soil with sandy to silty-sandy texture, favoring regression of the vegetation and a halophilic vegetation set up. In this study, we analyze the floristic com- position of the northern region of Hammam Boughrara using multiple floristic surveys con-ducted at three stations along the Tafna wadi. Dominated by Mediterranean and Saharo-Sin- dian elements, the relatively poor flora (88 spe-cies in total) is biologically characterized by a clear dominance of therophytes (>33%) and chama-ephytes (>19%) to the detriment of phanero-phytes.
