Abstract

Environmental problems have become very crucial for humanity. In fact, human activities bring important quantities of metal traces elements (MTE). This study has been made to remedy to these MTE by searching in the valley of Gounti Yena plants species able to be used in phytoremediation. At the end of this work, the floristic diversity of this valley is very remarkable. Indeed, 16 woody and 24 herbaceous have been inventoried; among them the Juliflora prosopis which is the dominant woody where as Eragrotis pilosa is the dominant herbaceous. The conformation with the bibliographic data has allowed holding back 10 herbaceous species and 4 woody species that could be hyper-accumulator.
