Abstract
The study area Agrakhal-Kunjapuri lies in district Tehri Garhwal. The present area of investigation lies at 30° 5' N latitude and 78° 23' E longitudes ranging in elevation of temperate zone and is covered with dense oak forest. Soil samples were collected from representative sites of the study area in each season viz. winter, summer and rainy. From each site, the composite samples (mixture of three soil samples) were collected from different depths (0-10, 15-25, and 30-40 cm). Soil samples of each site was analyze for physio-chemical characteristics. The soil of the study area was of clay-loam type. The biotic disturbance was found to be a determining factor of community formation, along with topography, soil and moisture.
