Abstract

Mangrove ecosystems contribute to biodiversity conservation and climate-change mitigation through carbon storage. This study assessed the association between biodiversity (flora and fauna) and carbon stocks in mangroves of North Sulawesi across three management contexts: a conservation zone (Bunaken), a protected forest (Sondaken), and an unprotected area (Bitung). Field surveys were conducted to compile species inventories, and carbon stocks were estimated from biomass measurements. Protected sites showed higher species richness and larger carbon stocks than the unprotected site. Species richness was positively and significantly correlated with carbon storage, indicating that sites with greater biodiversity also tended to store more carbon. These results support the role of effective protection in maintaining both ecological integrity and carbon sequestration capacity. In conclusion, strengthening mangrove protection in North Sulawesi is likely to deliver co-benefits for biodiversity conservation and climate mitigation.

Abstract

Woka (Saribus rotundifolius (Lam.) Blume.) is a palm tree that has significant ecological and socio-cultural value for the community of Bolaang Mongondow. However, local knowledge about its use and characteristics is threatened by extinction due to modernization. This study aims to: (1) identify the morphological characteristics of the woka plant, and (2) document the forms of utilization based on the local wisdom of the community of Bolaang Mongondow in managing woka. This study used qualitative methods with an ethnobotanical approach. Data were collected through field observations, in-depth interviews with key informants (traditional leaders and craftsmen), and documentation studies. The results show that woka has distinctive morphological characteristics, such as round fan-shaped leaves (rotundifolius) and strong stems. Woka has a wide range of uses, especially its leaves, which are used as roofing material for traditional houses (baloi), woven crafts for traditional ceremonies, and as food wrappers. Local wisdom is reflected in the knowledge system of sustainable harvesting techniques, traditional rules of harvesting, and beliefs that support the preservation of woka. It is concluded that woka is not just a plant but an integral part of the local cultural identity and ecosystem. This documentation is expected to serve as a database for the conservation and sustainable development of the economic value of woka.

Abstract

Hutan Produksi merupakan kawasan hutan yang diperuntukkan guna memproduksi hasil hutan, untuk memenuhi keperluan masyarakat, industri, dan ekspor. Untuk keperluan pengusahaan ini dikenal tiga macam hutan produksi, yaitu hutan produksi tetap, hutan produksi terbatas dan hutan produksi yang dapat dikonversi. Penelitian ini bertujuan untuk mengetahui tingkat keberhasilan dan persen tumbuh tanaman di hutan produksi Torout Desa Tambelang Kecamatan Maesaan Kabupaten Minahasa Selatan pada bulan November-Desember 2024 dengan menggunakan Metode Sistematis Sampling. BPDAS Tondano berperan dalam kegiatan rehabilitasi hutan dan lahan. Tingkat keberhasilan tanaman dalam kegiatan RHL di Hutan Produksi Torout Desa Tambelang Kecamatan Maesaan Kabupaten Minahasa Selatan dengan luas 100 ha mencapai 75,45 %. Terdapat 2 jenis tanaman yang ditanam yaitu, tanaman pokok berupa nantu (Palaquium obtusifolium) dan cempaka (Magnolia champaca) serta tanaman Multi Purpose Tree Species (MPTS) berupa alpukat (Persea americana), duku (Lansium domesticum), pala (Myristica fragrans), durian (Durio zibethinus), matoa (Pometia pinnata), dan kopi (Coffea Sp). Terdapat 8 kelas pengelompokan tinggi mulai dari 20 - 60 cm hingga 300 - 340 cm dengan kelas tinggi 60 - 100 cm merupakan kelas yang paling dominan, mencakup 28,04 % dari total tanaman yang diamati.

Abstract

Degradasi pada Daerah Aliran Sungai (DAS) disebabkan oleh penggunaan lahan yang tidak sesuai dengan prinsip konservasi tanah dan air sehingga mempengaruhi fungsi hidrologi suatu kawasan. Penelitian ini bertujuan untuk mengidentifikasi jenis-jenis tanaman yang berhasil tumbuh, menganalisos tingkat keberhasilan dan presentase tumbuh tanaman pada kegiatan RHL di kawasan Resort Dumoga Utara. Tingkat keberhasilan tanaman dalam kegiatan RHL di kawasan Resort Dumoga Utara Taman Nasional Bogani Nani Wartabone dengan luas 100 ha mencapai 76,256 %. Terdapat 2 jenis tanaman yang ditanam yaitu, tanaman pokok berupa nantu (Palaquium obtusifolium) dan cempaka (Magnolia champaca) serta tanaman Multi Purpose Tree Species (MPTS) berupa pala, durian, matoa, kemiri, dan alpukat. Terdapat 11 rentang tinggi yang dikelompokan, mulai dari 0-20 cm hingga 201-220 cm. Terlihat bahwa kelas tinggi 21-40 cm merupakan kelas yang paling dominan, mencakup 40,52% dari total tanaman yang diamati. Hasil ini menunjukan bahwa tingkat keberhasilan tanaman pada kegiatan RHL dianggap berhasil.
