Quautative Analysis of Vegetation from a Mixed Tropical Forest of Orissa, India

The present study provides informations about species composition of tree species along with their frequency, density, abundance and IVI data in four sampling sites from a forest patch of Barpahar Forest Range of Sambalpur, Orissa. Zlzyphus xylocarpa due to Its xerophytic adaptation was found to be dominant on the hill top which has either exposed rock layer or very thin soil layer. In the stiff south-western slope eight species were recorded with Clelstanthus as the dominant species. The foothill region having more soil and moisture supported more plant species with Butea monosperma as the dominant species Further analysis of the plant species of tour different sampling sites reveled relationship between diversity and dominance.
