Biodiversity interacting with the physical environment form the foundation of sustainable development. World’s forests extended over 4 billion hectares; corresponding to31percent of the total land area or an average of 0.6 ha per capita. Tropical forests in India comprising over 60% deciduous forests are poorly understood in terms of phytodiversity, phytosociology, quantification regimes. In peninsular India, quantification phytodiversity inventories are available from the forests of the Western Ghats, whereas study on Eastern Ghats is lacking. Gundla Brahmeswaram WLS the study area for the present work is located in Kurnool District, Andhra Pradesh one of the significant biodiversity rich areas in Southern Eastern Ghats to study the phytosociological attributes of tree species of the 124 tree taxa recorded from the sampled inventory. The tree density of the sampled inventory is 61.97 stem ha-1. IVI is the most important parameter to understood the community organization in relation to the competitive ability. GBM WLS although a protected area, needs further attention in terms of conserving valuable tree resources.
