The main basis of ecological research is the accurate identification of vegetation. Because it is an effective factor in measuring and evaluating the current situation and predicting the future situation of the region and will play an important role in proper and scientific management. For this purpose, in this study, the flora, life form and chorothype of plants in Bardkal watershed located in the northwest of Shiraz were introduced. The results showed 127 plant species which belong to 34 families and 102 genera. There are species in this watershed. The largest families Asteraceae with 24 species, Fabaceae with 17 species and Poaceae with 15 species, are in the first to third ranks, respectively.
