Abstract

Mangrove forest is a type of forest that grows in tidal areas, especially on protected beaches, lagoons, and river mouths whose vegetation communities can tolerate high salinity). This research began to be carried out from March to June located in Tampara village, South Kaledupa District, Wakatobi Regency, Southeast Sulawesi Province which aims to determine mangrove species, density, closure, and Important Value Index (IVI). The method used is line transect. The observations found 4 types of mangroves in the transect, namely Rhizophora stylosa, Bruguiera gymnorrhiza, Rhizophora mucronata, and Rhizophora apiculata. The density of trees and seedlings has a good density with an average of very dense criteria, while the mangrove sapling category has a damaged density and all stations have a rare density. The highest closure was Bruguiera gymnorrhiza 96.49% (station 4), the lowest was Rhizophora apiculata 2.75% (station 1). The highest overall IVI of mangroves was 200% of Rhizophora stylosa and Rhizophora mucronata (stations 2,3,4 and 7) and the lowest IVI was 39% of Rhizophora mucronata at station 5 seedling level.

Abstract

Nara Bay Beach has enormous marine resource potential with high biodiversity. One of the marine resources owned by Nara Bay Beach is seagrass beds. The purpose of this study was to calculate the composition, species density and cover of seagrass and to measure water quality parameters at Nara Bay Beach. The method used in collecting seagrass data at the location is the quadrant transect. The number of stations used is 3 stations. The results showed that Cymodocea rotundata had the highest species composition value of 73.48% (ST.3), the highest density was obtained by Syringodium isoetifolium of 161.8 (ST.3), the highest seagrass cover was obtained at ST. 3 and for water quality parameters (temperature, salinity, currents and pH) are still within optimum limits for seagrass growing.
