The objective of the present study was to examine the ecological indices and mapping the mangrove ecosystem in the coastal region of Maitara Island, North Moluccas Province. The study was conducted during 2015 at three stations. The results showed that 4 species of mangrove belong to 3 families were recorded during the study. The total density of stations was 215.78 tree/hectare, the frequency was 722.22 tree/hectare, the percent cover was 189.29% and the significant value was 300 in every station. Rhizopora apicullata, Avicennia alba, Sonneratia alba have the highest density and frequency, while the lowest density and frequency were Sonneratia caseolaris. Sonneratia alba, S. caseolaris, Avicennia alba have the highest percent cover. Overall, the diversity of mangroves is minor. The characterization of zonation showed that Rhizhopora sp. is a leading constituent of mangrove ecosystem from coast line to the hinterland of Maitara Island.

Mangroves forests have adapted themselves from exposure to strong waves with high salinity. Mangroves grow on mud flats flooded with sea water or brackish water during high tide or flooded throughout the day. Kukupang village is one of the capital of the District of Jouronga Islands are located in the South Halmahera in North Maluku province. Mangrove ecosystem has grown Kukupang village life along the coast with an area of approximately 65 hectares with the condition is still very natural growth. The research was conducted in October-November 2014 Location of the study took place in mangrove ecosystem Kukupang Village District of Joronga Islands, South Halmahera in North Maluku. Transect method of determining the station square and performed by stratified random method. Data retrieval is divided into three stations measuring 10 x 10 m for trees, 5 mx 5 m for the stake, 1 x 1 m for the nursery, where elucidation of the sampling stations are divided into three stations. Based on the results of the study are six mangrove species found are: Rhizopora apiculata, Avicennia marina, Rhizophora mucronata, Sonneratia alba, Brugueraea gymnorrhiza, Ceriops tagal. Distribution pattern associated mangrove ecosystem, and the highest level of density is the type of mangrove species Rhizophora apiculata, the condition of the substrate at the location of the dominant research dust
