Abstract

This study aims to examine the density, frequency and closure of mangrove areas. In addition, it also analyzed the ecological index (index of diversity, uniformity, and dominance) of mangrove vegetation in the waters of Ujung Batu, Flores Sea, Jeneponto Regency. This research was conducted using the 10 x 10 m2 transect plot method. The data obtained were analyzed to determine the density, frequency, closure and important value index (IVI) as well as to analyze the diversity index, uniformity and dominance index. The results of this study are; mangrove communities in the waters of the Ujung Batu, Flores coast, consists of types Avicennia alba, A. marina, A. officinalis, Sonnneratia alba and Rhizophora stylosa. A. alba dominates at the three observation stations (I, II and III). This is marked by the high importance (IVI) at all levels. The diversity index (H ') at the study site ranged from 0.36 - 0.51, indicating a low level of diversity. The Simpson dominance index (SDI) ranges from 0.34 to 0.54, indicating that one of the species (A. alba) dominates the mangrove area in the study site.
