Abstract

Abstract. Pricillia CC, Patria MP, Herdiansyah H. 2021. Environmental conditions to support blue carbon storage in mangrove forest: A case study in the mangrove forest, Nusa Lembongan, Bali, Indonesia. Biodiversitas 22: 3304-3314. Mangrove ecosystems can provide ecosystem services to mitigate climate change by absorbing and storing carbon in their systems. The question arises of how to manage a mangrove forest to store more carbon. The Nusa Lembongan mangrove forest was examined to assess the optimal environmental settings for blue carbon storage in the mangrove ecosystem. Five stations were selected purposively. The parameters observed in each station were aboveground living biomass, mangrove stand density, clay percentage in soil, bulk density, water content, soil organic carbon (%C), and soil organic nitrogen (%N). Based on this study, the total carbon stock in mangrove forest Nusa Lembongan was 68.10 ± 20.92 Mg C ha-1 and equals to 249.95 ± 76.77 MgCO2 ha-1 with a significant contribution of soil carbon stock. This study indicates that the essential parameters that can promote carbon sequestration in mangrove forest Nusa Lembongan were aboveground living biomass, soil organic carbon content and soil organic nitrogen content. In addition, as soil organic carbon content also negatively correlates with bulk density, it also can be considered. These findings can contribute to blue carbon planning and management to improve the effectiveness of the blue carbon project.

The environmental services of Pangarengan mangrove forest in Cirebon, Indonesia: conserving biodiversity and storing carbon

“…The minimum amount of carbon stock was 11.719 MgC/ha, and the highest was 590.310 MgC/ha. The variation of aboveground carbon stock in the mangrove forest was also recorded by Analuddin et al (2020) in the National Park of Rawa Aopa Watumohai, Pricillia et al (2021) in Bali, and Kusumaningtyas et al (2019) in the Segara Anakan Lagoon, Berau Marine Protected Areas, and Thousand Island, Indonesia. According to Kusumaningtyas et al (2019), Pricillia et al (2021), andAnaluddin et al (2020) data, the average of aboveground carbon stock was 969.8 MgC/ha in Rawa Aopa Watumohai National Park, Southeast Sulawesi, 68.1 MgC/ha in Nusa Lembongan, Bali, 130.1 MgC/ha in Berau Marine Protected Areas, East Kalimantan, 74.3 MgC/ha in Thousand Island, Jakarta, and 15.8 MgC/ha in Segara Anakan Lagoon, Central Java.…”

Carbon Sink Estimation of Mangrove Vegetation Using Remote Sensing in Segara Anakan, Cilacap

“…The ability of mangroves to store carbon has been carried out in several areas in the tropics. Mangrove forest in Nusa Lembongan Bali have total carbon stock 20.92 Mg/ha (Pricillia et al, 2021). According to (Wicaksono et al, 2016) there are approximately 120,546 tonnes carbon of mangrove biomass carbon stock in the Karimunjawa Islands with Above Ground Carbon mean value of 21.64 kg/m 2 .…”

Impacts of Climate Change on Blue Carbon Stocks and Fluxes in Mangrove Forests

“…Mangrove forests have the largest organic carbon (C ORG ) stocks of any of earth's ecosystems, with a global mean total forest stock of 692.8 ± 23.1 (±1 SE) Mg C ORG ha −1 (updated from [8] with [9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28]). Soil standing stocks average 516.4 ± 19.8 Mg C ORG ha −1 over the upper 1 m depth, accounting for 74% of total ecosystem standing stocks.…”

“…These large amounts of C ORG reflect rapid rates of soil accumulation on the forest floor, sustained accumulation over long time periods, and high rates of primary productivity. In contrast, global mean aboveground and belowground mangrove biomass average 105.8 ± 4.2 Mg C ORG ha −1 (±1 SE) and 68 Mg C ORG ha −1 , respectively, as updated from Alongi [8] with new data [9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28], which underscores the dominance of the soil component.…”
