Composition and Diversity of Swamp Plants In Lawa District, Southeast Sulawesi

Abstract

This research aims to determine the composition and diversity of seasonal swamp plants in Kasiono Oe, Lawa District, West Muna Regency, Southeast Sulawesi, and analyze environmental factors that influence the growth of Kasiono Oe swamp plants. This research is descriptive-quantitative research carried out at 5 stations in the swamp area, namely Station I (Lianoghule River flow), station II (Mata River flow), station III (Soni River flow), station IV (near settlements) and Station V (near plantations ). Location determination uses the path and grid method with a width of 20x20 (for the tree phase) and the line method (for the seedling, sapling, and pole phase), installing transects 50 m long with a length of 100 m. The results of the research showed that the composition of plant species found in Station I was found to be 4 plant species totaling 115 individuals, Station II 9 species totaling 71 individuals, Station III 5 plant species totaling 49 individuals, station IV 5 species totaling 61 individuals and station IV 8 species totaling 109 individuals. The diversity index for the tree stratum was 1.03, the pole stratum 0.63, the sapling stratum 1.3, and the seedling stratum for Station II 1.09 and Station V 1.01. The highest uniformity index for the tree stratum was 0.943, and the lowest was 0.918. For the pole stratum, it was 0.91; the highest for the sapling stratum was 0.97. The lowest was 0.81, the highest for the seedling stratum was 0.99, and the lowest was 0.81.
