A survey of natural vegetation, soil and water of Pakpattan District was undertaken in this study. Floristic data was analyzed by using multivariate analysis techniques i.e., Tow- way Indicator Species Analysis (TWINSPAN) and Canonical Correspondence Analysis (CCA). A total of fifty six species related to nineteen families were documented from forty quadrats in Pakpattan district. Two major and six sub plant communities were identified in the study area. The study also investigated the relationship of vegetation structure to selected environmental factors. This relationship was determined by CANOCO analysis. The distribution of species in relation to environmental variables indicated that although most of the variables were strongly correlated but failed to play major function in the grouping together of the species. This study also provided important information to preserve and improve the existing vegetation cover for conservation of indigenous flora.
