Abstract

The health condition of mangrove forests can be determined by assessing forest health indicators. One of the indicators used in determining the health of mangrove forests is faunal biodiversity. Measurement of forest health is a step that can be taken to ensure forest functions and benefits. The study's objectives were to determine the composition of mangrove species and mangrove forest fauna (birds and epifauna), to determine the structure of the fauna community which includes species diversity and species dominance and to determine the health condition of mangrove forests on Moti Island, Ternate Island District. This research was conducted on Moti Island, Moti District, Ternate City, North Maluku Province for six months, April - September 2021. A Sampling of mangroves was carried out using the "spot check" method. Meanwhile, the method used to assess mangroves' health condition refers to the FHM (Forest Health Monitoring) method. There are nine species of mangrove, namely Rhizophora apiculata, Rhizophora stylosa, Rhizophora mucronata, Bruguiera gymnorrhiza, Sonneratia alba, Xylocarpus granatum, Avicennia offincinalis, A. marina and Nypa fruticans. While the composition of fauna species is as many as 18 species consisting of Epifauna (Gastropoda = 12 species, Bivalve = 2 species) and birds as many as four species. The diversity of mangrove forest fauna species in all research locations is moderate and no species dominate. The health status of mangrove forests, both Tafaga and Figur villages, has 60% good condition, 20% moderate and poor conditions.

Abstract

The coconut crab is a marine biota that spends most of its adult phase in the terrestrial environment. Coconut crabs are also economically valuable because they can be traded as food ingredients and body frames used as home jewelry. However, the coconut crab is classified as a rare animal, and the distribution area is getting narrower. The purpose of the study was to determine habitat preferences and environmental characteristics. The research was carried out in the Tomajiko sub-district, Hiri Island district. Implementation time for six months from April – September 2021. Data Collection Procedure. The determination of the station is determined based on the difference in location or distance from the residential area. Sampling stations were determined at 3 (three) coconut crab fishing locations, namely stations I, II, and III with stations. The study results obtained 53 individuals who were female, 25 canary crabs, and 28 males, with a sex ratio obtained. During the study 1:1, there was a balance. Among the three stations, coconut crabs were mainly found in Station I, which had soil temperature, soil pH, and relative humidity suitable for the life of coconut crabs compared to other stations.

Abstract

The mangrove ecosystem is one of the main ecosystems in the coastal area which is very productive, but is very vulnerable to changes or external influences. As a vulnerable ecosystem, mangrove ecosystem management has to concern the integration of the community's ecological, economic and socio-cultural aspects so that optimal and sustainable management is achieved. The research objectives were to know the composition of mangrove species, to determine the structure of the mangrove forest community (species diversity, species dominance, uniformity, species density, species cover) and to determine the condition of mangrove forests on Tarnana Island, Jailolo Selatan District. This research was conducted on Tarnana Island, Jailolo Selatan District, and West Halmahera Regency in January - February 2021. The sampling method was carried out using the spot check method. Sampling was carried out at the lowest tide by using 5 line transects and each line transect placed 5 plots. Data analysis included species diversity, species dominance, uniformity, species density and species cover. The composition of mangrove species on Tarnana Island was obtained as many as 8 species, namely Rhizophora apiculata, R. stylosa, Bruguirea gymnorrhiza, Ceriops decandra, Ceriops tagal, Sonneratia alba, Xylocarpus granatum and Avicennia alba. The structure of the mangrove community has moderate species diversity, no dominant species and moderate uniformity. The condition of the mangrove forest on Tarnana Island is in the damaged category with rare density.
