Abstract. Sugiana IP, Andiani AAE, Dewi IGAIP, Karang IWGA, As-Syakur AR, Fharmawan IWE. 2022. Spatial distribution of mangrove health index on three genera dominated zones in Benoa Bay, Bali, Indonesia. Biodiversitas 23: 3407-3418. A study forest stratification was conducted Bay which experienced high coastal development pressures during the last decade. The aimed to determine (MHI) and community structures along genera-dominated were Sonneratia, Rhizophora Bruguiera. Random method applied classify areas distributed bay. Forest structure assessed with 54 plots. mainly composed Sonneratia-dominated a respective area proportion at approximately 51% 45%. Those by R. mucronata S. alba an importance value (IVI) 266.35% 145.57%, respectively. narrow Bruguiera zone B. gymnorrhiza domination found most landward area, only covering 4% area. Overall accuracy kappa coefficient indicated classification 97% 0.94 We that 47.44% could be classified into highest healthiness category indicating is excellent condition. made significant contribution entire state since coverage this 73.80%.
