The current exploration was focused to study vegetation and environmental parameters associated with Sahiwal district. For the phytosociological survey Braun-Blanquet’s methodology was employed. In order to classify the vegetation data, ordination research tactics i.e., Two Way indicator species analysis (TWINSPAN) and Canonical Correspondence Analysis (CCA) were used. Vegetation data obtained from forty quadrats was compiled. Thirty eight plant species belonging to twenty one families were recorded. TWINSPAN bifurcated the flora of entire study zone into two main communities that had been again separated into smaller i.e., sub communities. Canonical correspondence analysis recognized the relation of vegetation assembly to underlying environmental factors. This correlation was studied by CANOCO analysis. In the Canonical correspondence analysis of species for Sahiwal, it was found that environmental variables, i.e. water content, soil EC and water EC had clear influence on species distribution.
