Coastal Vegetation Diversity on Baai Island, Kampung Melayu District, Bengkulu City

BAAI Island has a coastal forest formed from various communities and vegetation structures, which have functions including as a tourist area, a source of food, and disaster mitigation. The aim of this research was to find out the composition, structure and diversity of coastal vegetation on Baai Island area, west of Sumber Jaya Village, Kampung Melayu District, Bengkulu City. Sampling was taken using the transect line plot method with a size of 20 x 20 m for trees, 10 x 10 m for poles, a plot size of 5 x 5 m for saplings. The results showed that the composition of the coastal vegetation at the tree level found 11 families, with a total of 11 species. 5 species came from the pole level, and 4 species with a total of 11 individuals from the sapling level. The species of Casuarina equisetifolia obtained the highest value index of importance at the tree level, while the species Ardisia elliptica had the important value index for the stakes and saplings. The results of the calculation of the Shannon-Wiener diversity index (H'), of all growth levels show a value <1.0 which means low diversity, less stable.
