Popis: Tree diversity assessment, inventoried in tropical moist evergreen forest yielded a total of 62 tree species belongings to 44 genera and 23 families and 5140 stems which wereenumerated in 10 ha plots.; International audience; Natural forest of Eastern Ghats is degrading due to various anthropogenicpressures. In a present study to assess the tree diversity and populationstructure in the tropical forest of Javadhu hill Eastern Ghats, Tamil Nadu,India, total of 62 tree species belonging to 44 genera and 23 families and5140 stems were enumerated in 10 ha plots. Memecylon umbellatum wasthe predominant tree species followed by Psydrax dicoccos, Chloroxylonswietenia and Anogeissus latifolia. The mean density was 514 stems ha-1and the density of trees ranged from 469-623 ha-1. The basal area in all thestudy plots ranged from 19.4 m2/ha to 33.2 m2/ha and the mean basal areafor the 10 ha plots was 19.87 m2/ha. All top five species had greater densityand basal area in 30-90 cm girth class. The Euphorbiaceae aretaxonomically diverse and constituted the most-speciose family followedby Combretaceae. The species richness of deciduous species was greaterfollowed by evergreen and brevi-deciduous. The present study reveals thatthe forest ecosystem restores considerable tree diversity here which isunder more threat due to anthropogenic pressure. Therefore, immediateconservation measure is required to preserve the vanishing forestresources.
