Soil microbial diversity is of utmost importance for functioning of any ecosystem. Samples from coastal region of Gujarat, that is, from Alang, Daman, Mandvi, Okha, Porbandar and Veraval, and from desert areas of Bhuj, Dhordo and Khavda were collected. The purpose of our study was enumeration and functional diversity analysis of 14 functional microbial groups of microorganisms present in both ecosystems and correlation of microbial data with abiotic parameters as well as with important soil enzyme activities. Functional diversity was analysed using CLPP. Finally, correlation between abiotic parameters and microbial data was done using SPSS, and various diversity indices values were calculated. We concluded that in comparison to coastal soil, desert soil exhibited high diversity, total activity and richness. PCA analysis displayed that coastal samples were clustered together, while the desert samples were separated from each other and from the coastal samples group. The coastal sites of Okha, Porbandar and Veraval seemed to be deteriorating with low microbial diversity.
