Abstract


This study aims to determine the composition and diversity of plant species in the Dulamayo Utara Natural Resources Management Unit (UPSA), Telaga Biru District, Gorontalo District. The method used in this research is the roaming method for exploration of plant species. The research found that there are 24 types of plants in the UPSA area, namely Aleurites moluccanus, Bambusa vulgaris, Ceiba pentandra, Cinnamomum verum, Musa × paradisiaca, Myristica fragrans, Piper aduncum, Citrus × aurantiifolia, Citrus sp, Cordyline fruticosa, Euphorbia pulcherrima, Ficus ampelas, Ficus septica, Gliricidia sepium, Lantana camara, Nicotiana tabacum, Psidium guajava, Ricinus communis, Durio Zibethinus, Ficus sp, Helianthus annuus, Mallotus sp, Mangifera indica, and Syzygium aromaticum. The H 'value of plants at the tree, sapling, and seedling levels was 1.88; 2.32; and 2,38, indicating a moderate level of diversity. This value indicates that the evenness at the tree, understorey, and seedling level is stable. Species Richness (R1) of plants at the tree, sapling, and seedling levels, respectively 1.47; 1.94; 2.1, belongs to the low category.
