Abstract

Mangrove forest is a natural resource typical of tropical coasts, which has multiple benefits with a very broad impact when viewed from social, economic and ecological aspects. Management of natural resources must be very prudent because it takes a long time to be able to recover when damage / extinction has occurred. The purpose of this study was to determine the composition of mangrove species, the structure of mangrove forest vegetation (species density, relative density of species, frequency of species, relative frequency of species, species cover, relative cover of species and important values) and to determine the level of damage. Extraction of mangrove vegetation using the "spot check" method. The transects are drawn perpendicular to the coastline along the mangrove vegetation. The composition of mangrove species were 7 species, namely Rhizophora apiculata, R. stylosa, Bruguirea gymnorrhiza, Ceriops tagal, Sonneratia alba, Xylocarpus granatum and Aegiceras floridum. In the vegetation structure, the highest density and relative density were found in Rhizophora stylosa and the lowest was Xylocarpus granatum. The highest species and relative frequencies were Rhizophora stylosa, R. apiculata and the lowest were Bruguiera gymnorrhiza. The highest type and closure were Sonneratia alba and the lowest was Ceriops tagal. Meanwhile, the highest importance was in Sonneratia alba and the lowest was Xylocarpus granatum. Overall, the density value of mangrove species on Manomadehe Island is 2796 trees / ha so that the condition of the mangrove forests on Manomadehe Island is still in the good category (very dense).

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.
