Abstrak

Research about coastal forest vegetation in Sabutung island has been conducted.The aim of this research was to make an inventory of native species, introduced speciesand invasive spesies of plant in Sabutungisland. Sampling activities conducted withpurposive sampling method.Data collected with noted the plant species that foundduring exploring the island. All sample are photographed. Unidentified sample werecollected and identified in Marine and Environmental laboratory, Department ofBiology, Faculty of Mathematics and Natural Sciences, Hasanuddin University.Identification of the sample conducted based on: An Annotated Check-List of TheVascular Plants of The South China Sea and Its Shores by Turner et al. (2000) and Mangrove Guidebook for Southeast Asia by Wim Giesen et al.
