Floristic Diversity of Atriplexaies in Western Algeria

Abstract

This Work is applied to study of evolution of vegetal to Atriplex of two different areas, the North and South of Western Algeria. This area presents a remarkable biodiversity by the vegetal halophiles habitations. The vegetal, in manner of general Tlemcen region, see its surface; this is for great part to human and climat action. The knowledge of particularly biologic and ecologic of these halophytes species in general is in all action of biodiversity. Ghezlaoui and al, 2009. The bioclimatic done in evidence to region study level, two types of climat, a climat for North area (Zenata, ES-Senia) and a climat for south area (Mecheria, Naama and Ain-sefra). We effect 50 floristic lists in each station to complete lists of halophytes species wich are in study’s area. Vegetal covert is dominated by therophytes, then chamaephytes and phanerophytes in last position. This general manner, the floor of soils always poor and characterized by special species and it’s the chenopodiaceae family Ozenda, 1958.
