Coastal Forest vegetation of Sabutung Island South Sulawesi

Abstract

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 species
and invasive spesies of plant in Sabutungisland. Sampling activities conducted with
purposive sampling method.Data collected with noted the plant species that found
during exploring the island. All sample are photographed. Unidentified sample were
collected and identified in Marine and Environmental laboratory, Department of
Biology, Faculty of Mathematics and Natural Sciences, Hasanuddin University.
Identification of the sample conducted based on: An Annotated Check-List of The
Vascular 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. (2007)for coastal forest
species; Tropical flowering plants: a guide to identification and cultivation by Kirsten
Albrecht Llamas (2003) for introduced species andNonnative Invasive Plants of Pacific
Coast Forest. A Field Guide for Identification oleh Gray et al. (2011) and Guide to The
Naturalized and Invasive Plants of Southeast Asia by Arne Witt (2017) for invasive
species. Data were analysed descriptively and displayed in tabular form. Antropogenic
impact i.e: land conversion and increased population were also discussed. From the
results of the study were recorded as many as 221 species of plants in Sabutung Island.
Mostly dominated by ornamental plants and cultivated (introduced) plants with 131
species of 46 tribes followed by native species with 67 species from 34 tribes. Invasive
species were recorded with at least 19 species from 8 tribes. Nonetheless, invasive
species are widespread and dominate space in almost all parts of the island. Most of the
coastal forest on Sabutung Island has been lost due to land conversion to settlements
and garden/plantation.
