The mangrove ecosystem is one of the natural resources that is the target of conservation, from the various potential natural resources that exist in the Wakatobi National Park. Mangrove ecosystems support biodiversity conservation, by providing shelter, breeding grounds, nursery, and feeding grounds for various types of animals including several groups of animals that are threatened with extinction, from reptiles, amphibians, aves, and mammals. Mangrove ecosystems can also protect coral reef ecosystems and seagrass. The aim of this research was to analyze the composition and diversity of mangrove species and to formulate a mangrove ecosystem management strategy in Kaledupa Island. This study uses a vegetation analysis method and a SWOT analysis. The results of vegetation analysis showed that there were eight species of mangroves on Kaledupa Island which were divided into four families. These species of mangroves are Avicennia marina, Xylocarpus granatum, Bruguiera gymnorrhiza, Ceriops decandra, Ceriops tagal, Rhizophora apiculata, Rhizophora mucronata, and Sonneratia alba. The highest and lowest mangrove species diversity indexes in Kaledupa Island were shown by the weaning and seedling strata, respectively with values 1,86 and 1,66. Based on the results of the SWOT analysis, mangrove ecosystem management strategies were formulated, namely (1) utilizing the status of the mangrove ecosystem as a conservation area and the existence of strict regulations to preserve mangroves so that they have the potential to become attractive ecotourism areas and (2) empower communities to provide mangrove seeds through the establishment of a nursery so that rehabilitation is no longer hampered by the reason that there are no seeds that are ready for planting.Abstrak Ekosistem mangrove merupakan salah satu jenis sumberdaya alam yang menjadi target konservasi, dari berbagai potensi sumberdaya alam yang ada di kawasan Taman Nasional Wakatobi. Ekosistem mangrove mendukung konservasi keanekaragaman hayati, dengan menyediakan tempat tinggal, tempat berkembang biak, tempat pengasuhan anak dan tempat mencari makan berbagai jenis hewan, termasuk beberapa golongan hewan yang terancam kepunahan, mulai dari golongan reptil, amphibi, aves, dan mamalia. Ekosistem mangrove dapat juga melindungi ekosistem terumbu karang (coral reefs), dan padang lamun (sea grass). Tujuan penelitian ini adalah untuk menganalisis komposisi dan keanekaragaman jenis mangrove serta merumuskan strategi pengelolaan ekosistem mangrove di Pulau Kaledupa. Penelitian ini menggunakan metode analisis vegetasi dan analisis SWOT. Hasil analisis vegetasi menunjukkan bahwa terdapat delapan jenis mangrove di Pulau Kaledupa yang terbagi ke dalam empat famili. Jenis mangrove tesebut adalah Avicennia marina, Xylocarpus granatum, Bruguiera gymnorrhiza, Ceriops decandra, Ceriops tagal, Rhizophora apiculata, Rhizophora mucronata, dan Sonneratia alba. Indeks keanekaragaman jenis mangrove tertinggi dan terendah di Pulau Kaledupa ditunjukkan masing-masing oleh strata sapihan dan semai dengan nilai 1,86 dan 1,66. Berdasarkan hasil analisis SWOT, dirumuskan dua strategi pengelolaan ekosistem mangrove yaitu (1) memanfaatkan status ekosistem mangrove sebagai daerah konservasi dan adanya regulasi yang ketat untuk menjaga kelestarian mangrove sehingga berpotensi untuk dijadikan daerah ekowisata yang menarik dan (2) memberdayakan masyarakat untuk menyediakan bibit mangrove melalui pembentukan kebun bibit sehingga rehabilitasi tidak terhambat lagi dengan alasan tidak tersedianya bibit yang siap tanam.

The purpose of this study was to find out the diversity index of molluscs (gastropods & bivalves) based on mangrove degradation level in Tobea Island of Muna Regency. The data were collected from May until July 2017, in Wangkolabu municipal area of Tobea sub-district, using observation method and direct observation in the research location to find out the index of ecology of molluscs such as index of diversity (H'), evenness (E), density (N), dominance (D), and dispersion pattern (Id) from both gastropod and bivalve classes based on mangrove degradation level. Direct identification in the field is applied to the type of mangrove vegetation and mollusc organisms that have been known by it’s scientific name. But if not, then the samples are taken and the documentation is then done further analysis at the Laboratory of Biology Unit of Ecology and Taxonomy of FMIPA UHO with reference to the guide book of Introduction of Mangrove in Indonesia and book Snail & Shell Indonesian. Then for water environment parameters in the form of water and substrate samples are further analyzed at Biology Laboratory of UHO Forensic and Biomolecular Unit using Miller triangle fraction method and APHA standard method. Statistical analysis is done using Excel Stat to determine the major components affecting the ecological index of molluscs in degraded mangrove areas. The results showed four species mangroves in Wangkolabu Village are Rhizophora mucronata, Rhizophora apiculata, Bruguiera gymnorrhiza, and Sonneratia alba and that mangrove degradation on the coast of Tobea Island, Wangkolabu village, Tobea sub-district has varied values for good mangrove criteria (Density/RDi = 1.600 individuals/hectare), medium mangrove (Density/RDi = 1.175 individuals/hectare), and mangrove broken/rare (Density/RDi = 375 individuals/hectare). Besides that, Cerithium spp., Nerita costata, Terebralia sulcata, and Clypeomorus sp., type gastropods is able to adapt to mangrove forests that have moderate density (RDi= 1.000–1.500 individuals/hectare), with mangrove substrate types in the form of sandy loam that has soil organic content (BO = 3,18%). While the gastropod type Telescopium telescopium prefers low density mangrove forests (RDi < 1.000 individuals/hectare) with the type of substrate in the form of clay containing organic matter (BO = 2,35%). Based on the results of the study it is expected that the need for mangrove forest management in the study area for the sustainability of aquatic biota, especially molluscs that can be developed as conservation areas by looking at the level of mangrove damage through non-fish aquaculture activities (shellfish) for the welfare of coastal communities and islands small in Southeast Sulawesi.

Water bird diversity in mangrove ecosystem of the Malili District, East Luwu Regency, South Sulawesi, is rarely studied. This reseacrh aims to examine the diversity of bird species in the mangrove ecosystem, Malili District, East Luwu Regency, South Sulawesi. The study was conducted at two stations, namely mangrove forests at the Lakawali River estuary and at the Ussu River estuary. Data collection was carried out using field by field methods, observations were made with binoculars and a Nikon D5200 DSLR camera. Data analysis was performed using the Diversity Index (H’) formula according to Shannon-Winner and evenness index (E) according to Magurren. Species conservation status is determined based on Minister of Environment and Forestry Regulation No. P.106/MENLHK/SETJEN/ KUM.1/12/2018 and IUCN redlist. The results showed that 417 individual birds were found consisting of 5 orders, 7 families and 17 species, there was one protected species, namely great knot (Calidris tenuirostris). The diversity index (H’) in the estuary of Lakawali river is 2.48, and in the estuary of Ussu river is 2.59 which indicates the medium category. The evenness index (E) in the estuary of Lakawali river was 0.92 and in the Ussu River was 0.93 which showed that the distribution of species in both habitats was quite even.
