A quantitative ecological study was conducted in Pachaimalai(PM) of Southern Eastern Ghats (SEG), Tamil Nadu to estimate density, species richness and aboveground biomass of trees. A 10 ha long term forest dynamics plot was established in study area. All trees ≥10cm diameter at breast height (DBH) were recorded and tagged with consecutively numbered permanent aluminium tags for continuous monitoring and further survey. 10 ha plot was sub-divided into two hundred and fifty 20m × 20m workable sub-plots for tree inventories. An allometric formula has been developed through destructive sampling method to estimate aboveground biomass stockpile of trees in semi evergreen forests. In total, 29 species recorded from Pachaimalai hills. As a whole, 2127 trees recorded from study plot. Density of trees varied considerably among species, Memecylon umbellatum represented by 1470 individuals followed by Buchanania lanceolata (246 trees) and Clausena dentata (72 trees).
