Tree Species Diversity and Population Structure in the Tropical Forests of North Central Eastern Ghats, India

The tree species diversity and population structure were studied in four stands of the tropical forests in the north-central Eastern Ghats, based on tree inventories conducted on four 1-ha plots. In the four independent plots, two 5 x 1000 m transects were established and all trees with </span>...
