The study was aimed at to investigate the hydro-edaphic properties of Woodland habitat of Nilgiris Biosphere Reserve (NBR) and their possible relationship with its flora.

The present investigation deals with natural chemical reserves and physical characteristics of leaf litter of 35 dominant tree species of Nilgiri Biosphere Reserve and efficacious impact of leaf litter of a few selected species on physico-chemical properties of sodic soil.

The present investigation deals with the chemical characteristics/composition of the natural waters of the Nilgiri Biosphere Reserve (NBR), located within Kerala and Karnataka states respectively. Waters of both localities differ significantly in their chemical characteristics and composition. The waters of NBR - Kerala are bereft of dissolved minerals in their per unit volume, irrespective of their sources and location. In contrast to above, the waters of Karnataka have sufficient dissolved minerals in their per unit volume.
