Daftar Isi:
- Mangrove is an ecosystem that is a habitat for various both aquatic and terrestrial biota. This research aims at revealing the distribution and community structure of mangrove in Donrotu, Guratu and Manomadehe Islands, West Halmahera Regency, North Maluku. This work was conducted from April to June 2019. Data collection using the spot check method, while the analysis of mangrove distribution was carried out qualitatively. Community structures quantitatively include type density (Di), relative density types (RDi), frequency types (Fi), relative frequency types (Rfi), closing types (Ci), closure of relatively types (RCi), and Important value (VIi). The results showed that Rhizophora stylosa in the three islands (Donrotu, Guratu, and Idamdehe) had the highest species density and highest density values. Closing types and closures are relatively varied. The type of R. stylosa also has a higher importance in all three islands. The highest mangrove density was mainly found in Donrotu Island (0.96 ind/m2), then Guratu Island (0.46 ind/m2), and Idamadehe Island (0.32 ind/m2), respectively.
- Mangrove merupakan ekosistem yang merupakan habitat bagi berbagai biota perairan maupun di darat. Penelitian yang dilakukan ini bertujuan untuk mengungkapkan distribusi dan struktur komunitas hutan mangrove di Pulau Donrotu, Guratu dan Manomadehe Kecamatan Jailolo Selatan, Kabupaten Halmahera Barat, Maluku Utara. Pelaksanaan penelitian pada bulan April-Juni 2019. Pengambilan data dengan menggunakan metode spot check. Analisis data distribusi mangrove dilakukan secara kualitatif, sedangkan struktur komunitas secara kuantitatif meliputi kerapatan jenis (Di), kerapatan relatif jenis (RDi), frekuensi jenis (Fi), frekuensi relatif jenis (Rfi), penutupan jenis (Ci), penutupan relatif jenis (RCi), Nilai penting (VIi). Hasil penelitian menunjukkan bahwa mangrove jenis Rhizophora stylosa pada ketiga pulau (Pulau Donrotu, Guratu dan Manomadehe) memiliki nilai kerapatan jenis dan kerapatan relatif jenis yang lebih tinggi. Penutupan jenis dan penutupan relatif jenis bervariasi. Jenis R. stylosa juga memiliki nilai penting yang lebih tinggi di ketiga Pulau. Kerapatan mangrove tertinggi ditemukan di Pulau Donrotu (0,96 ind/m2), kemudian Pulau Guratu (0,46 ind/m2) dan Pulau Manomadehe (0,32 ind/m2).
