Loss of biodiversity is a threat to the natural ecosystem in any particular area locally and leads to ecological imbalance as a whole globally. So study of the plant biodiversity is an important parameter to understand and assess the plant population structure. so the studies of Phytosociological parameters are essential for protecting the natural plant communities and biodiversity as well as understanding the changes experienced in the past and continuing on in to the future. Phytosociology deals with plant communities, their composition and development, and the relationship between the species within them is the study of groups of species of plant that are usually found together. Phytosociology is the study of the characteristics, classification, relationship and distribution of plant communities and it is useful to collect such as data to describe the population dynamics of each species studied and how they relate to the other species in the same community. in short the special Feld of study of plant communities with respect to their components structure and classification forms the basis of division of ecology called phytosociology.
