This paper describes the status and tree species diversity of Semi-Evergreen forests in Chitteri Hills, Tamil Nadu. Stratified random sampling method and distribution of sample plots using vegetation maps prepared from IRS LISS III FCC was used to study the tree species having girth :::30 cm at breast height. A total number of 466 stems from 51 tree species were recorded from the study area representing 24 families and 40 genera. The total basal area was 21.92 m2. Anogeissus latifolia was the highest contributor (19.29) followed by Memecylon edule (17.93), Psydrax dicoccos (11) and Nothopegia colebrookiana (10). Memecylon edule (47.26), has the highest IVI value followed by Anogeissus latifolia (46.77), Psydrax dicoccos (38.34) and Nothopegia colebrookiana (28.87). Percentage of family important value was high in Combretaceae followed by Anacardiaceae, Verbenaceae, Rubiaceae, Ebenaceae and Euphorbiaceae. Shannon-Weiner and Simpson diversity Index value were 2.76 and 0.11.
