Struktur komunitas dan pemetaan ekosistem mangrove di pesisir Pulau Maitara, Provinsi Maluku Utara, Indonesia

Mangrove is ecosystem important in coastal area. Human exploited make decrease habitat mangroves ecosystem. The highly activity in this area threaten quantity ecology ecosystem mangroves.The objective of the present study was to examine the ecological indices and mapping of mangrove in coastal region on Maitara Island, North Moluccas.Information about that most important for sustainable mangrove management. The results showed that mangroves composition found that 4 specieses belong to 3 families.total density of stations namely 215.78 tree/hectare, frequency 722.22 tree/hectare, percent cover 189.29% and significantion value 300 every stations. The density and frequency highest of species found Rhizopora apicullata, Avicennia alba, Sonneratia alba. The density and frequency lowest Sonneratia caseolaris. The percent cover highest types derived Sonneratia alba, Sonneratia caseolaris, Avicennia alba and percent lowest is Sonneratia caseolaris. Overall the ecological index analysed diversity of mangroves found is minor.

Mangrove merupakan ekosistem penting di daerah pesisir.Meningkatnya exploitasi manusia menurunkan habitat ekosistem mangrove. Tingginya aktivitas mengancam kuantitas ekologi ekosistem mangrove.Tujuan penelitian ini untuk melihat struktur komunitas dan pemetaan ekosistem mangrove. Pengambilan data mangrove dilakukan pada tahun 2015. Hasil penelitian menemukan bahwa komposisi jenis mangrove yang ditemukan terdiri dari 3 family dengan 4 spesies. Total keseluruhan kerapatan stasiun yaitu 215.78 batang/hektar, frekuensi 722.22 batang/hektar, tutupan 189.29% dan nilai penting 300 tiap stasiun. Kerapatan dan frekuensi jenis tertinggi ditemukan Rhizopora apicullata, kemudian Avicennia alba, disusul Sonneratia alba dan terendah Sonneratia caseolaris. Tutupan jenis tertinggi diperoleh jenis Sonneratia alba, kemudian Sonneratia caseolaris, disusul Avicennia alba dan terendah Rhizopora apicullata. Nilai penting tertinggi pada jenis Sonneratia alba, kemudian Rhizopora apicullata, seta
