It is necessary to understand habitat conditions and quantitative variables of medicinal plants for better management and use of medical productions. These characteristics are the indicators of habitat growth which are under some limitations of arid environments. In the present research, the effect of flood irrigation on quantitative variables of medicinal species Dendrostellera lessertii (Van Tiegh) at Gareh Bygone plain of the Fars was studied. The crown coverage and density of the species were measured using plot and amount of aboveground and underground biomass were measured by double sampling method and Profiles were dug beside the species at two sites of without and with water spread conditions. The results showed that there were no significant difference (p5%) of water spread on quantitative parameters of the plants. These results show that these plant species were tolerant to water stress under harsh environment and they may be established in arid areas. On the basis of these results, the study of autecology, the methods of cultivation, establishment and also, effect of limitation factors on establishment of these plant species were recommended for the vast areas of arid areas of Iran.
