Entire district falls within Deccan trap area, however the common soil types are the black, loamy and clay. Some western part of district enjoys average annual rainfall exceeding 500 mm while eastern side has the rainfall less than 300 mm. These variations in environmental condition have helped this region to be rich in floral biodiversity. Present work was carried out to explore the diversity of blue green algae from Satara district. Variety of habitats from 82 localities were screened to explore blue green algae from the district. Between June 2010 to May 2013 in all 127 species from 36 genera belonging to 4 orders were recorded. Out of these 28 species were unicellular while 99 were filamentous. Filamentous forms were found to be dominant over unicellular forms.
