Diversity in natural ecosystem is due to different environmental variables which affect vegetation composition. Such environmental factors sustain plant communities of a specific region. It is very difficult in developing countries to access to remote areas frequently. In Pakistan Swat Valley part of Hindu Kush range of mountain is one of the remote area where plant diversity of different regions have not been studied related to environmental factors. The current study of vegetation was formulated to study the different effect of environmental variables on plant species organization and diversity of different vegetation communities of Eelum hill part of district Swat. Also this research identifies threats from different environmental factors and suggestion for remedial measures. For assessment of environmental variability quantitative ecological techniques were carried out during summer 2013. To locate a characteristic species with environmental variables underlying a specific community, Data attribute plot was used. Elevation and Aspect are the strongest variables and show Significant effect on species composition and distribution in different plant communities.
