Abstract


Otanaha Fortress is a tourist attraction in Gorontalo Province. This tourist attraction has a variety of plants that live and become the center of attention for visitors who come. This study aims to determine the composition and structure of plant vegetation in the tourist attraction of Otanaha Fort, Gorontalo City. The method used in this research is the plot strip method (combination of plots and transects), with a plot size of 20m x 20m for the tree level, 10m x 10m for saplings, 5m x 5m for the seedling level. be the basis for determining the type composition. To measure the structure of plant vegetation by calculating the Real Density (KR), Relative Frequency (FR), and Relative Dominance (DR). Lannea cormendelica, Leucaena leucocephala, Streblus asper, Swietenia mahagoni, Ficus benjamina, Caesalpinia pulcherrima, Jatropha curcas, Samanea saman, Lepisanthes rubiginosa, Garuga floribunda, Annona muricata, and Mimosa pudica. The highest IVI at each level, namely the tree level Swietenia mahagoni with an IVI of 63.26%, the stake level Caesalpinia pulcherrima with an INP of 78.26%, and seedling rate for Mimosa pudica with an INP of 61.01%.
