ABSTRACT-Floristic inventory and diversity assessment are necessary to understand the present diversity status of the conservation of biodiversity. Shorelines are one of the most rapidly changing places on the Earth. The Gulf of Kachchh (GoK) is a semi-enclosed coastal indentation with predominance of mangrove ecosystems, coral reefs, associated rich marine diversity and coastal terrestrial vegetation. Halophytes are flowering plants, which are naturally found in saline habitats such as coastal swamps, coastal dunes, inland salt flats etc. Present works reveals the diversity of halophytes in GoK. Total 27 halophytes were encountered from 13 coastal talukas and islands of GoK. Islands of GoK, and Bhachau taluka are the area with highest diversity in GoK. In the present study α diversity (Shannon diversity index, Simpson's Index, species richness, evenness index) of the halophyte community was studied. From the study of biodiversity it was observed that highest species diversity (Shannon-Wiener diversity H') was observed in Jamnagar district and its islands whereas species richness index (d) was highest in Devbhumi Dwarka district and its islands. Evenness index (e) was highest (0.528) in Morbi district.
