“…Kawasan ekosistem mangrove juga menjadi salah (Asadi, 2018).Keunikan yang dimiliki perlu adanya partisipasi masyarkat Peunaga Cut Ujong. Hasil komponen pengetahuan tentang penyediaan karbon ini juga didukung komitmen pemerintah Indonesia dalam menangani hilangnya mangrove dalam skala besar ditunjukkan dengan upaya percepatan restorasi gambut dan mangrove melalui pembentukan Badan Restorasi Gambut dan Mangrove (Soeprobowati et al, 2023). Hasil penelitian ternyata menunjukan bahwa sehingga pandangan masyarakat terhadap fungsi kawasan sebagai penyediaan karbon tinggi itu menandakan masyarakat paham bahwa mangrove salah satu sumber karbon (Qur'ani et al, 2023).…”

Local communities played an important part of thepi existence of the mangrove ecosystem in Peunaga Cut ujong Village. Community perspectives on the existence of mangrove ecosystems have an impact on mangrove management steps in the local area. The purpose of this study was to identify community perceptions of the existence of mangrove ecosystems around the Peunaga Cut Ujong Village community. This research uses survey methods and in-depth interviews using a questionnaire sheet as a guide. The technique of determining respondents through snowball sampling. Respondents totaled 35 people who were selected based on the area of residence of the youth hamlet of Peunaga Cut Ujong Village. Data analysis of this research used Likert scale. The results showed that community perceptions of the functions and benefits of mangrove ecosystems had the lowest score of 858, the form of management score 916, and the level of participation with a score of 1246. Overall, the perceptions and opinions of local communities about the existence of mangrove ecosystems are in the very good category, with a score of 127. This value shows that the existence of mangroves is very good in the view of the Peunaga Cut Ujong community. Community involvement in mangrove conservation efforts will actually have an impact on the success of sustainable management.

Mangroves on the islands along the Java Sea play a crucial role in supporting biodiversity, protecting coastlines, and sequestering carbon. However, there is a lack of information on mangrove structure and biomass in the area. This study aimed to assess the mangrove structures and biomass on Desa Daun, located on the Bawean Islands, and Kemujan Island, located on the Karimunjawa Islands, respectively. The study utilized a combination of line transect and quadrant plot methods with a size plot of 10x10 m. We established 7 line transects and 28 quadrant plots in the mangrove forest of Desa Daun and similarly set up 7 line transects and 21 quadrant plots on Kemujan Island. Within each quadrant, the mangrove species were identified, and their diameters at breast height (DBH) were recorded. To assess the relative significance of each species, the importance value index (IVI) was calculated, and allometric equations were applied to estimate biomass and carbon storage in the trees. PlanetScope imagery was also used to quantify the carbon stock of mangroves on those islands. In Desa Daun, 13 mangrove species were identified, while 12 species were recorded on Kemujan Island. The species Nypa fruticans and Excoecaria agallocha exhibited the highest IVI in Desa Daun and Kemujan Island, respectively. Notably, Rhizophora apiculata demonstrated the greatest biomass in both locations, with measurements of 43.08 Mg B/ha in Desa Daun and 102.22 Mg B/ha in Kemujan Island. Overall, mangrove stands on Desa Daun stored biomass of 113.60 Mg B/ha and carbon of 50.98 Mg C/ha, whereas mangrove stands on Kemujan Island stored biomass of 295.04 Mg B/ha and carbon of 131.95 Mg C/ha. Mangrove stands of the whole Bawean Islands sequestered 22,941 Mg C, while Karimunjawa Islands hold much higher C stocks, 79,451 Mg C. Despite being smaller in size, the Karimunjawa Islands have more extensive mangrove coverage compared to the Bawean Islands due to their geomorphological characteristics, which in turn influence their mangrove structures and carbon stocks. However, the loss of mangroves in the Karimunjawa Islands due to aquaculture expansions could increase carbon loss in the islands.

IntroductionMultiple factors, including human disturbance and environmental change, have caused a significant global mangrove resource loss. Therefore, the Chinese government has restructured mangrove habitats and restored the ecosystem functionality through establishing naturally protected mangrove areas. Despite efforts spanning several years, over 90% of mangrove forests in China have been now integrated into the natural protected area system, with the health status and influencing factors of mangrove ecosystem remaining a pertinent subject for further exploration. Given the intricacies of mangrove ecosystems with complex nonlinear relationships among evaluation factors, it is imperative to adopt scientific methodologies to assess their health status.MethodsTo illustrate this, we conducted a mangrove ecosystem health assessment of natural protected areas of Guangdong Province, China. By employing a fuzzy comprehensive evaluation method and establishing an index system for mangrove ecosystem health assessment.ResultsThe results revealed the following findings. (1) Various factors exert differing degrees of influence on mangrove ecosystem health. Notably, the mangrove habitat pattern (weight 47.95%), bird diversity (weight 20.97%), mangrove community (weight 14.31%), water environment (weight 11.76%), and soil sedimentary environment (weight 5.01%) were identified. (2) Overall, the mangrove ecosystem within protected areas of Guangdong exhibited unhealthy signs. There were 4 healthy protected areas (20.00%), 4 areas classified as sub-healthy (20.00%), and 12 were deemed unhealthy (60.00%). (3) Key factors contributing to the compromised health of mangrove ecosystems included the homogenization of mangrove plants, decreased habitat diversity, and exogenous pollution.DiscussionBy planting local mangrove species, scientifically managing the ratio of mangrove cover area to mudflat area, and controlling pollution sources and treating pollutants, the structure of the mangrove ecosystem can be optimized, and the quality of mangrove forest can be improved. These findings can enhance mangrove ecosystem management practices, assist mangrove natural reserve managers in performing targeted mangrove ecological protection and restoration, promote effective management, and contribute to the realization of “harmonious symbiosis” between humanity and nature within mangrove ecosystems.
