We assessed tree diversity of tropical dry deciduous forest in Rajasthan at five sites (Jalmahal, Ramgarh, Nahargarh, Jhalana and Digota). A total of 102 circular plots was laid and all tree species %26gt;= 10 cm girth at breast height were enumerated. Tree diversity totalled 69 species and the Digota site harboured the maximum number of families (19), genera (25) and species (36). Mimosaceae (7 genera and 15 species) was the most species-rich family at all the sites. Shannon diversity (2.44) and species heterogeneity (2.23) were highest for Ramgarh site while species richness and 6 diversity were highest for Digota (3.62 %26 5.55) site. Cassia fistula, Butea monosperma and Ehretia laevis were the only species exhibiting regular distribution while all others showed random or contagious distribution. The forest composition varied across the sites. The study provides an understanding of tree distribution at landscape level.
