Abstract

This study aimed to describe floristic composition and ecological chracteristics of six species of halophytes (Arthrocnemum macrostachyum, Halocnemum strobilaceum, Juncus rigidus, Phragmites australis, Suaeda vera and Zygophyllum aegyptium) in north part of Nile Delta of Egypt. Eighty-two species (40 annuals, one biennial and 41 perennials) of 73 genera and 24 families. Asteraceae, Poaceae, and Chenopodiaceae were the largest represented families.. Therophytes and chamaephytes were the dominat life forms. The widespread chorotype were Mediterranean taxa (82 species or about 73.18%). TWINSPAN segregated four groups. Group A codominated by J. rigidus and P. australis, group B by P. australis and Z. aegyptium, group C by Rumex pictus and Erodium laciniatum and group D by Zygophyllum album and H. strobilaceum. Soil salinity, soil texture and human activities were the key drivers fordistribution of the studied halophytes in the study area. The Deltaic Mediterranean coast should be protected against excessive human activities
