Drought acceptance is the ability to which a plant maintains its biomass production during arid or drought conditions. Some plants are naturally modified to dry conditions, existing with defense mechanisms such as drought tolerance, detoxification, or restore of xylem disorder. It affects the plant morphological, physiological, biochemical and molecular attributes with adverse impact on photosynthetic capacity. Growth pattern and structural arrangement, decrease in transpiration loss through altering stomata conductance and distribution, leaf rolling, root to shoot ratio dynamics, root length growth, accumulation of well-matched solutes, and enhancement in transpiration efficiency, osmotic and hormonal regulation, and delayed senescence are the strategies that are adopted by plants under water insufficiency. The sophisticated adjustment that improves the water stress tolerance and adaptation in plants for the biodiversity richness even in summer are briefly discussed during the study. Total 26 herbs including small shrubs were listed out of which 13 are seasonal/ annual, 03 are annual to perennial and 10 are perennial. Total 13 plants out of 26 are useful as forage even in month of summer. Some seasonal plants start to germinate in month of February -March and grow in climax during month of May- June and bloomed in very short period of time.
