    Abstract

    Vegetation covering an area has a definite structure and composition developed as a result of long term interaction with biotic and abiotic factors, and any change in the status of these factors will disturbs the floristic composition of the environment. Five quadrates each in six line-transects, or total 30 quadrates, with sampling size of 20x20 m2 for trees, 10x10 m2 for poles, 5x5 m2 for sapling and 2x2 m2 for seedlings was selected for analysis of vegetation to quantify the composition and dominance of the species. The highest Importance Value Index (IVI) for tree species was that of Lagerstroemia speciosa (89.45) followed by Gluta renghas (64.53) and Mangifera indica (22.48) For poles, the highest IVI values was also Lagerstroemia speciosa (106.04), followed by Psidium guajava (32.20) and unidentified species #17 (28.04). In saplings stage, Mimosa vigra (177.11) has the highest IVI, followed by Strobilanthus sp. (50.13) and Lagerstroemia speciosa (14.28). For seedlings, the highest IVI values was that of Micania mucronata (90.26), followed by Centrosoma sp (33.38) and Mimosa vigra (31.93). Lagerstroemia speciosa, Gluta renghas and Mimosa vigra were found to be the most dominant species in the study area
