Abstract


The diversity of mangrove vegetation is a community that has different characteristics from other communities. Diversity is an important component in mangrove management, but so far the availability of data related to mangroves is still very minimal, including those related to the species diversity of mangrove forest vegetation in the region. This study aims to obtain data on species diversity of vegetation found in the mangrove forest area of Dusun Besar Village, Pulau Maya District, Kayong Utara Regency. Method used was a combination of path and plot method, and the determination of the location and research path location were carried out using purposive sampling. The results of observation and data analysis showed that the dominant vegetation species with the highest importance value index (INP) for seedlings, saplings and trees was the Avicennia marina, namely the INP value of seedlings 37.04%, the INP values of sapling 65.24%, and the value of INP a tree rate of 65. Based on the results of the most dominant analysis found the species of  Avicennia marina with a value of C = 0.03430 for seedling, C = 0.04729 for sapling, and C = 0.04736 for tree level. The diversity of mangrove forest vegetation species in Dusun Besar Village for seedlings, saplings and trees is low because it has an H 'value <1, and the abundance of mangrove vegetation species was not evenly distributed in each forest area because it only has an e value <1.
