Abstract

Abstract. Rumondang AL, Kusmana C, Budi SW. 2021. Species composition and structure of Angke Kapuk Mangrove Protected Forest, Jakarta, Indonesia. Biodiversitas 22: 3863-3871. Angke Kapuk Mangrove Protected Forest (AKMPF) is one of the protected forests in the coastal area of DKI Jakarta, Indonesia. This area is important for the north coast of Jakarta, hence it has function to protect the land from sea abrasion, seawater intrusion, and seawater flooding. This study aims to determine the condition of forest structures and species composition in the Angke Kapuk Mangrove Protected Forest (AKMPF) to obtain useful information for sustainable mangrove forest management. Vegetation data were collected using the sampling unit of transect for tree and line plot for forest regeneration inventories. Those data were analyzed for the density, frequency, dominance, species diversity, and species distribution pattern. The obtained results show that AKMPF consists of 13 mangrove species, including 7 species of true mangrove, 5 species associated mangrove, and 1 species of palm, with the dominant species, are Avicennia marina for tree with its regenerations and Acrostichum aureum for groundcover. Overall, the species diversity index in this area was classified as low category. Mangrove trees in this area have height class between 4-28 meters formed bell-curve, while stem diameter class were between 10.00-69.75 cm formed L-curve. The distribution pattern of species in this areal generally was clumped.

Mapping of mangrove forest and carbon stock estimation of east coast Surabaya, Indonesia

“…This study in Surabaya has identified 5 species of mangroves, which is nearly identical to research in the nearest mangrove forest in Pasuruan (Isroni et al 2019). Other studies on the coasts of major cities, namely Jakarta Bay and Muara Kapuk, have identified 5 to 9 mangrove species (Rumondang et al 2021;Sari et al 2019). The number of mangrove species found in remote areas with natural mangrove forests is considerably higher, as evidenced by studies in Mimika Papua (66 species), Segara Anakan Cilacap, Central Java (16 species) and Kutai National Park, East Kalimantan (17 species) (Poedjirahajoe et al 2019;Setyadi et al 2021;Widyastuti et al 2018).…”

Spatial distribution of mangrove vegetation species, salinity, and mud thickness in mangrove forest in Pangarengan, Cirebon, Indonesia

“…The dominant species were R. mucronata and A. marina (Figure 4). Three of the dominant families in this mangrove forest (Rhizophoraceae, Acanthaceae, and Lythraceae) were also reported in Angke Kapuk Mangrove Protected Forest, Jakarta (Rumondang et al 2021), and mangrove revegetation area in Karangsong, Indramayu District, West Java (Gunawan et al 2017). Least concern Rare Rare Rare Rare Notes: *rare (frequency < 20%), occasional (21%-40%), frequent (41%-60%), common (61%-80%), abundant (> 80%) ( As shown in Figure 4, R. mucronata in the Pangarengan mangrove forest had the highest IVI for seedlings, saplings, poles, and trees.…”

“…Nonetheless, different results on dominant species were found in other studies. For instance, A. marina had the highest IVI in Angke Kapuk Mangrove Protected Forest, Jakarta (Rumondang et al 2021), andSegara Anakan Lagoon, Cilacap District, Central Java (Widyastuti et al 2018). Rhizophora apiculata was the dominant species (69%) in the secondary mangrove forest in Bintuni, Papua (Yudha et al 2021), S. alba had the highest IVI in Tanah Merah mangrove forest, East Nusa Tenggara (Sadono et al 2020).…”

Short Communication: Structure and composition of mangrove vegetation in Lembar bay area, West Lombok District, Indonesia

“…Based on the research results of Eddy et al (2019), the dominant species of tree, sapling and seedling levels in the Air Telang Protected Forest, South Sumatra were Nypa fruticans, R. apiculata and Acrostichum aureum, respectively. Rumondang et al (2021), The dominant species in Angke Kapuk Mangrove Protected Forest (AKMPF) DKI Jakarta were A. marina for a tree with its regenerations and A. aureum for groundcover. According to Ali et al (2018), The A. marina and R. mucronata were two mangrove species with the highest important value index at each growth level in the Ujungpangkah coastal, region Gresik, East Java Province.…”
