Abstract. Amalia C, Wulandari I. 2023. Vegetation analysis of angiosperms at Paguyangan Enclave Zone, Ir. H. Djuanda Forest Park. Pros Sem Nas Masy Biodiv Indon 9: 170-177. Indonesia has high flora potential, about 30,000 plant species, of which approximately 24,000 are flowering plants (angiosperms). The high level of plant species in Indonesia, especially angiosperm plants, both endemic and foreign species, provide strategic opportunities for flora conservation. One of the plant conservation sites developed in Indonesia is Ir. H. Djuanda Forest Park, which has an abundant of flora. The purpose of this research is to determine the composition and structure of angiosperm vegetation in Ir. H. Djuanda Forest Park, especially in the Paguyangan enclave zone. The stratified quadratic plot method was used by observing all the growth plant phases (seedlings, saplings, poles, and trees). The analysis shows that the vegetation composition of the angiosperms group in the research area consists of 34 species from 21 families. Furthermore, the analysis shows the vegetation structure in the research area is dominated by several species of angiosperms within each growth phase, including cacabean or dempo spinach (Alternanthera philoxeroides) in the seedling phase; white calliandra (Zapoteca portoricensis) in the sapling phase; and kihujan (Albizia saman) in the pole and tree phases. White calliandra requires further research due to its invasive and potential and eliminate local plant species.
