“…Piranto et al (2019) also found that the high diversity of mangrove species and substrates in Pramuka Island, Jakarta Bay affected the diversity of mollusks, especially species from the Gastropoda class. In mangrove ecosystem in Lombok Island, Mujiono (2016) stated that the highest species diversity was found in the seaward zone. The geographical factor of mangrove forests of the seaward zone located on the coast allows gastropod species from the sea to enter, either intentionally to find food or because they are carried away by waves.…”

Abstract. Ginantra IK, Muksin IK, Suaskara IBM, Joni M. 2020. Diversity and distribution of mollusks at three zones of mangrove in Pejarakan, Bali, Indonesia. Biodiversitas 21: 4636-4643. The diversity of mangrove species in mangrove zonations on the coast of Pejarakan plays an important role in the existence of faunal diversity, including those from mollusks. Mollusks are the dominant phylum associated with mangrove habitats, in addition to the species of the Crustacean subphylum. This research aimed to determine the diversity of mollusks and their distribution patterns in three mangrove zones in Pejarakan, Buleleng District, Bali Province, Indonesia. Data collection was conducted by establishing sampling plots across three mangrove zones, i.e. seaward zone, middle zone, and landward zone. There were 23 sampling plots in total with size of each plot was 1x1m. The species and number of individuals of each species of mollusks were recorded in each quadrat plot. The diversity of mollusks was calculated using the Shannon-Wiener index, evenness index, and dominance index, while the pattern of distribution of mollusks was measured using the Morisita index. The results of the study found 27 species of mollusks, consisting of 19 species from Gastropods group, 7 species from Bivalvia group and 1 species from Polyplacophora (chiton). The seaward zone showed the highest species diversity, while the landward zone had the lowest. Terebralia palustris had the highest abundance with 217 individuals/m2 and was distributed in the three mangrove zones. Planaxis sulcatus showed the highest abundance (87 ind./m2) in the seaward zone, and Telescopium telescopium showed a fairly high abundance and were distributed in the mid zone and the landward zone. In general, mollusks in the mangrove area of Pejarakan was distributed in a group/clustered pattern. The data from this research can serve as a reference in mangrove forest conservation efforts and mangrove forest used for ecotourism.

“…Kerusakan hutan mangrove merupakan masalah serius yang kini sedang terjadi hampir di seluruh Indonesia, termasuk di pulau Lombok. Mujiono (2016) memenyatakan kawasan hutan mangrove Pulau Lombok yang masih dalam kondisi baik hanya sekitar 1.643 ha atau sekitar 49,7% dari total 3.305 ha kawasan hutan mangrove Pulau Lombok. Sebagai upaya mengurangi laju kerusakan hutan mangrove, maka dilakukannlah rehabilitasi ekosistem mangrove.…”

“…Jika dilihat dari fauna asosiasi mangrove yang ditemukan di kedua lokasi penelitian, keanekaragaman jenis fauna di ekosistem mangrove alami Pemongkong jauh lebih tinggi dibandingkan dengan ekosistem rehabilitasi Gerupuk. Terdapat 34 spesies moluska asosiasi seperti Cherithidea spp., Littorina spp., dan sebagainya (Zvonareva et al, 2015;Mujiono, 2016;Yolanda, 2016)…”

Abstrak : Rehabilitasi mangrove merupakan salah satu upaya yang dilakukan untuk mengurangi laju kerusakan hutan mangrove di Indonesia salah satunya di kawasan Teluk Gerupuk. Penelitian ini bertujuan untuk mengetahui kondisi mangrove hasil rehabilitasi di Teluk Gerupuk dengan mebandingkan struktur vegetasi mangrove di kawasan tersebut dengan ekosistem mangrove alami. Pelaksanaan penelitian dilakukan pada bulan April-Juni 2019 di dua kawasan hutan mangrove di pesisir selatan pulau Lombok yaitu hutan mangrove alami desa Pemongkong dan hutan mangrove rehabilitasi Teluk Gerupuk. Pengambilan data dilakukan dengan menggunakan metode transek berpetak dengan ukuran petak 10 x 10 m untuk tipe pohon, sub petak 5 x 5 m untuk tipe pancang, dan petak semai berukuran 2 x 2 m. Terdapat 11 spesies mangrove ditemukan di dalam plot penelitian dengan persebaran spesies yaitu 8 spaesies ditemukan di hutan mangrove alami Pemongkong dan hanya 7 spesies ditemukan di hutan mangrove rehabilitasi Gerupuk. Spesies mangrove yang dimaksud termasuk ke dalam 4 famili yaitu Avicenniaceae (Avicennia alba, A. marina, A. lanata), Rhizophoraceae (Ceriops decandra, C. tagal, Rhizophora apiculata, R. mucronata, R. stylosa), Rubiaceae (Scyphiphora hydrophyllaceae) dan Sonneratiaceae (Sonneratia alba, S. casiolaris). Struktur vegetasi kedua ekosistem sangat berbeda terlihat pada vegetasi penyusunnya. Hutan mangrove alami Pemongkong didominasi oleh jenis Sonneratia alba dan Avicennia alba yang memiliki Indeks nilai penting (INP) untuk tipe pohon dan pancang dengan nilai masing-masing 132,37 dan 141,52, sedangkan hutan mangrove rehabilitasi didapatkan INP tertinggi pada tipe pohon dan pancang yaitu jenis R. apiculata dan R. stylosa dengan INP berturut-turut 140,5 dan 116,41. Rehabilitasi hutan mangrove dengan metode yang selama ini dilakukan telah mengubah struktur vegetasi hutan mangrove di Pulau Lombok yang juga dapat mempengaruhi fauna asosiasi dan ekosistem sekitar mangrove. Oleh karena itu, diperlukan perencanaan serta analisis terlebih dahulu terhadap lokasi tujuan rehabilitasi mangrove agar untuk terbentuknya hutan mangrove rehabilitasi yang lebih sesuai dengan biota asosiasi dan ekosistem sekitar yang telah ada sebelumnya.Kata Kunci : Struktur Komunitas, Mangrove, Alami, RehabilitasiAbstract : Rehabilitation of mangrove vegetation was an effort in order to decrease the rate of mangrove ecosystem destruction. This research aimed to determine the vegetation structure and the community status of natural and rehabilitation mangrove forest at South Lombok seashore. This research held on March – June 2019 at two types of mangrove ecosystem such as natural ecosystem at pemongkong, East Lombok and rehabilitation ecosystem at Gerupuk bay, Central Lombok. Data collection used plotted transect method by placed a plot sized 10x 10 m alternately. There are 11 species of mangrove found which belong to 4 families such as Avicenniaceae (Avicennia alba, A. marina, A. lanata), Rhizophoraceae (Ceriops decandra, C. tagal, Rhizophora apiculata, R. mucronata, R. stylosa), Rubiaceae (Scyphiphora hydrophyllaceae) and Sonneratia (Sonneratia alba, S. casiolaris). Vegetation structure in these 2 location was different based on the composition each vegetation and it proportion. Natural mangrove forest in pemongkong dominated by Sonneratia alba with importance value reached 132,37, meanwhile the rehabilitation area of mangrove ecosystem Gerupuk dominated by Rhizophora apiculata with number of importance value reached 140,5. These differences drove the value of persent of similarity (PS) between these ecosystem only reached 10.41% which categorized as low similarity. Mostly of rehabilitation of mangrove ecosystem conducted cause the alteration of vegetation structure of mangrove in Lombok coastal and affect the mangrove associated fauna and ecosystems. In that case, it really important to analys the condition of mangrove rehabilitation plan location to determine the mangrove species to plant in order to formed a rehabilitiation of mangrove area which more compatible to its associated biota and ecosystems.Keyword : Structure, Mangrove, Natural, Rehabilitation

Lombok, an island that lies in the Lesser Sunda Islands, is popular for the tourist destination. One attempt to promote tourism is through the biodiversity of its fauna. This study aims are to summarized the diversity of gastropoda and made a checklist to make it easier studied. Museum collections and fifteen works of literature were used as the data source. A total of 74 families and 292 species of gastropoda were documented from 29 locations. Twenty-one species are new records for Lombok Island. About 29% of them have their representation in the museum collections. The list dominated by marine (65%), following by terrestrial (15%), mangrove (6%), and freshwater species (5%). The most diverse family, Neritidae, which occupies wider habitat is represented by nine percent. Littoraria scabra is the most widely distributed species which occurs in 12 locations. The five most diverse locations were marine habitats which popular for tourism destinations. This study contributes to the development of marine ecotourism.
