It is an area of outstanding scenic beauty and has atracted the atenton of geologists, naturalists and geomorphologists for over a century. One of the unique habitats in the Western Ghats are the rocky plateaus. Previous studies have covered plant species compositon, geological and geomorphological status of the rocky plateaus. An analytcal study of microhabitats and associated therophytes of four rocky plateau sites was conducted. The study sites were Durgawadi Plateau, Naneghat Plateau which are basalt outcrops and Zenda plateau and Amba Plateau, which are laterite outcrops on the escarpment of the northern Western Ghats. The results revealed a correlaton between basalt and lateritc rock outcrops as well as ephemeral plant elements. All four outcrops are similar in their nutrient status but the microhabitats of these plateaus are extremely diferent from each other. Keywords: Basalt, ephemeral, geology, laterite, Rock outcrop, therophytes. DOI: htps://doi.org/10.11609/jot.4980.11.10.14334-14348 Editor: Aparna Watve, Biome Foundaton, Pune, India.
