Abstract
The population dynamics of tree species were studied in both deciduous and evergreen forests at Kodayar in the Western Ghats of Tamil Nadu. The mortality of trees was less than the number of new recruits, resulting in a net gain in population density and basal area. The increase in net population density and basal area of tree species could be because of their entry into the adult stage from the already existing sapling and seedling bank. Greater mortality of juveniles than that of adults could be due to intense competition for limited available resources at the juvenile stage. The present study concludes that to a larger extent, the forest ecosystems here are at building phase. Long-term studies are needed to understand the regeneration niche.
