Research on the dominance of Nypa fruticans in Mangrove Ecosystems: composition and vegetation studies in the coastal area of Nagari Mandeh, West Sumatra. The purpose of this study was to determine the composition, structure and diversity of mangrove vegetation in areas invaded by invasive plants. The method used in this study is the quadrat method which is placed along the transect line. The results found the composition of plants at the tree level as many as 3 families, 3 species with a total of 58 individuals. At the sapling level, 5 families, 6 species and 716 individuals were found. While the lower plants found 5 families, 5 species and 873 individuals. The dominant species at the tree level is Rhizophora apiculata with an INP of 271.25%, the sapling level is Nypa fruticans species with the highest INP of 200.81% and the lower plants are also dominated by Nypa fruticans species, 111.59%. Meanwhile, the diversity index at the research site is low, Shannon-Wiener's H' which states that if H ≤ 1 indicates that the diversity of a species is low. Invasive species found were Nypa fruticans, Hibiscus tiliaceus, Melastoma malabathricum. Invasive plants, especially Nypa fruticans, have a significant negative impact on aquaculture areas in coastal areas, especially those that depend on mangrove ecosystems.
