The present study is aimed to prepare the floristic biological spectrum and to estimate the functioning of ecosystem at Chalama region of Nallamala forest. The study revealed the presence of 302 species that belongs to 218 genera, distributed in 74 families. The families Fabaceae and Poaceae are represented with 20 species in each. Forty one families are represented with a single species in each. It indicates the well operated and dynamic community. 155 species of herbaceous flora among 302 species indicates the efficient utilization and withholding of nutrients. In the present exploration, phanerophytes and therophytes showed maximum divergence. Percentage of phanerophytes is showing similarity with normal biological spectrum indicates humid bio climate of the area. Therophytes showed highest deviation from the normal spectrum. Chamaephytes, cryptophytes and hemi cryptophytes are showing fewer departures. It is concluded that the study area is showing Phanero – Therophytes due to sub tropical climate. The study area is furnishing with high percentage (37.7) of therophytic life form and less percentage of other life forms is probably due to anthropogenic activities and fire catchment disturbed the area so that annual therophytes re-established in the area when it is receiving rainfall.
