Methodology: The data collection method is carried out using vegetation analysis where this method is a combination method between the path method and the banded line. The number of plot paths used in this study was 47 plots. The distance between the plot of the paths is 20 meters. Determination of the observation path plot is carried out by purposive sampling. Data obtained in the field were analyzed using the Shannon-Wienner species diversity index. Results: The study's results found 61 types of plants at the sapling level, 29 at the pole level and 47 at the tree level. The plants that dominate Batuputih Nature Tourism Park (BNTP) at the level of Original Research Article
