Preliminary survey on the diversity and economic values of tree species was carried out in Krishnagiri taluk, Krishnagiri District, Tamil Nadu. A total of 115 tree species belonging to 90 genera and 36 families were recorded. Fabaceae is the most dominant family (18 genera and 28 species), and Ficus is the dominant genus with seven species, while seventy-three genera had only one species.Among the total number of species, nineteen species were recorded as edible fruit yielding trees (19 species), avenue trees (13 species), dye plants (17 species), medicinal plants (42 species), ornamental trees (14 species), oil yielding plants (8 species), exotic trees (17 species), and timber yielding trees (30 species). Few tree species, such as Mangifera indica, Cocos nucifera, and Tamarindus indica, were supporting the livelihoods of local peoples. Four gymnosperm species were observed: Cupressus sempervirens, Araucaria heterophylla, Cycas circinalis, and C. revolute.
