Abstract. Utina R, Katili AS, Lapolo N, Dangkua T. 2019. Short Communication: The composition of mangrove species in coastal area of Banggai District, Central Sulawesi, Indonesia. Biodiversitas 20: 840-846. The mangrove ecosystem possesses unique ecological functions. This research is one part of the activities to prepare reports on mangrove condition in Banggai District, Central Sulawesi Province, Indonesia. The objectives of this study were to explore the composition of mangrove species and mangrove zoning in coastal area of Banggai. The data were collected by survey method spread within 16 spots, with a total area of 7,387 hectares. The data were analyzed with descriptive qualitative methods. The results showed that there were 32 families of mangrove plants in Banggai, classified into 53 species, consisting of 25 true mangrove species and 28 associated mangrove species. An endangered species of mangrove was found, i.e., Scyphiphora hydrophyllacea. This endangered species was found only in Tingki-tingki Village and Uwedikan Village (Balean and Potean Island) of Banggai. The pattern of mangrove zoning within the research site follows the pattern of mangrove zoning commonly found all over Indonesia. The Rhizophoraceae family (Bruguiera gymnorhiza, Rhizophora mucronata, Rhizophora apiculata, Rhizophora stylosa, Rhizophora lamarchii and Ceriops tagal) was found more often than the other families in study site. It means that the Rhizophoraceae family had wide distribution area within site.

Potential analysis of location, socio-culture and biodiversity as ecotourism attraction in Valentine Bay on Buano Island, West Seram, Maluku, Indonesia

“…The back zone was dominated by X. granatum (Figure 7) with the highest IVI at seedling (54.67%), poles (60.88%), and trees (71.25%) where this area was the closest to dry plain. Utina et al (2019) also stated that X. granatum was found growing in the back zone where the substrate is a dry plain and has a wide distribution in mangrove forests in Banggai district, Central of Sulawesi, Indonesia.…”

Short Communication: Structure and composition of mangrove vegetation in Lembar bay area, West Lombok District, Indonesia

“…It grows well to the interior as long as it still gets a good supply of saltwater. Besides that, according to Sari et al (2019), Srikanth et al (2015, Utina et al (2019), and Syarifuddin and Zulharman (2012) that mangrove plants have unique adaptability to the environment such as adaptation to low oxygen levels, adaptation to high salinity, adaptation to unstable soil.…”

“…The dominant mangrove species at each tree, sapling, and seedling level at the study site were R. mucronata, R. stylosa, C. tagal, and B. cylindrica. According to Utina et al (2019), All of these dominant species are mangrove species in the Rhizhoporaceae family. This family was found more often than the other families in the study site.…”

Characteristics of Sentigi (Pemphis acidula) As Environmental Bioindicators of Mangrove Conservation in the Regional Marine Conservation Area Gili Sulat, East Lombok, Indonesia

“…Rhizophoraceae has the highest number of species, namely Bruguiera gymnorrhiza, Rhizophora mucronata, R. apiculata, Rhizophora stylosa, and Ceriops tagal. While Pemphis acidula has been found separated with the sandy habitat from another species (Utina et al, 2019). Besides, Pemphis acidula could be categorized as a rare species among the mangrove vegetation because of its functional and economic usage so that it is traditionally harvested and valued as a bonsai species (Ellison et al, 2010, Utina et al, 2019.…”
