Abstract

Assessment of soil seedbank composition of woody species in Ramsai Range, Gorumara National Park

Author(s): Anup Kumar Sarkar

Now a days the depletion of forests and the need for their restoration are well recognised. In restoring forests, the first step is to quantify the actual and potential levels of  natural regeneration ability of plant by examining the role of soil seed banks as propagule donors. In present work, soil seedbank assessment of woody plant species was made in Ramsai forests so as to evaluate composition and estimate their regeneration status. A total of 24 quadrates were established in selected six sites of the forest. The quadrates (20m x 20m) were laid along line transects.Composition and status were determined by direct count. Results showed the presence of seeds of 14 plant species in the soil. Shorea robusta had the highest seed density and Importance Value Index.The similarity between the soil seed bank, and above-ground vegetation was more or less same in most of the quadrate sites. Regeneration was abundant in some species, but poor in many others. The natural regeneration process should therefore be assisted through direct seeding planting .
