“…Our results support that mangrove forests are traps [9] for the medium-/big-size, land-/ocean-based floating debris. Additionally, our results suggest that the pneumatophores of a mangrove forest act as a filter, which can not only prevent the land-based debris from entering the marine environment through the river but also prevent the sea-based debris from being dispersed into the terrestrial environment again by tidal currents and waves [9,26]. We agree with the viewpoint that mangroves are akin to sinks for marine debris.…”

“…The marine debris pollution (including plastics and microplastics) in mangrove forest regions is actually affected by both natural factors (i.e., hydrodynamics, mangrove height and density, etc.) and human activities (mariculture, tourism and coastal dumping) [26][27][28][29]. Thus, it is essential to develop an appropriate method of marine debris monitoring in mangroves to provide effective recommendations and practical guidance, and to conduct surveys to assess the impact of human activities on coastal zones.…”

A modified approach for marine debris investigation in mangrove forests is developed, including some practical programs, viz., sampling location, time, area, materials, size and sources data processing. The marine debris method was practiced in the Beilun Estuary mangrove forest region in Fangchenggang in 2019, viz., the debris items were classified, counted, weighed and recorded, and the marine debris pollution was assessed to understand the impact of human activities. The results show that the mass density is 21.123 (2.355~51.760) g/m2, and more than 90% came from the land-based and human activities. More than 60% of the total debris weights are plastics, followed by fabrics (17.91%) and Styrofoam (10.07%); the big-size and oversize debris account for 76.41% and 13.33%, respectively. The quantity density is 0.163 (0.013~0.420) item/m2, and ~95% came from land-based human activities. More than 75% of the total debris items were plastics, followed by Styrofoam (14.36%), fabrics (4.10%) and glass (3.59%); the big-size, medium-size and oversize debris are 76.41%, 13.33% and 10.26%, respectively. The results suggest that mangrove forests are barriers for the medium-/big-size marine debris, acting as traps for marine debris. Our study provides recommendations and practical guidance for establishing programs to monitor and assess the distribution and abundance of marine debris. The results show that mangrove areas in the Beilun Estuary are filled with some plastic debris (plastics plus Styrofoam) and that the density and type at Zhushan and Rongshutou near the China-Vietnam border are more than those at Shijiao and Jiaodong. The results of this study are also expected to not only provide baseline data for the future assessment of Beilun Estuary mangroves but also to help China and Vietnam strengthen marine land-based pollution control and promote coastal wetland and mangrove conservation, marine species conservation and sustainable use.

“…In addition, the presence of inorganic waste can reduce the fertility level of the soil in mangroves, which can affect the growth rate and sustainability of mangroves. Based on the ecological aspect, mangrove mortality can disrupt the population of various types of biota that are associated in the mangrove ecosystem [14]. waters serve as shelter for inorganic waste such as plastics, so that plastic does not enter the land around residential areas.…”

Technological developments, especially in remote sensing in mangrove mapping are growing. One of them is the use of Unmanned Aerial Vehicle (UAV) as a vehicle for capturing aerial photo data. This study aims to map the mangrove ecosystem in order to find out spatial information with UAV technology and to identify mangrove species, distribution, and associations. The ground survey was conducted on 02 until 04 May 2019 in North of Lancang Island, Seribu Islands, DKI Jakarta Province. The mangrove data collection was carried out in four stations with marking, tracking the mangrove area and drone flights for taking aerial photo data. Based on the research, it was found that the mangroves were in good condition with an area of around 4 hectares, consisting of Rhizophora mucronata. However, there is a lot of waste around the mangrove ecosystem, especially inorganic waste in the form of plastic. Where the presence of garbage can cover the roots of the mangrove so that it can affect respiration and cause death in mangroves. The application of UAV technology that is integrated with GIS in mangrove ecosystem mapping is expected to be an alternative in extracting mangrove databases for future coastal ecosystem management.

“…While Tunicatimonas might not serve any purpose in promoting host health, their increased abundance could be a consequence of plastic pollution. Plastic pollution is a recognised problem in Southeast Asia, and much of this plastic can become entangled within mangroves where it can disrupt growth and lead to ecological instability [93, 94]. We hypothesize that plastic debris could be facilitating the transport of t Tunicatimonas into mangrove ecosystems, particularly since Tunicatimonas taxa are found enriched on pneumatophores, a structure ideally suited to trapping plastic debris.…”

Microbes have fundamental roles underpinning the functioning of our planet, they are involved in global carbon and nutrient cycling, and support the existence of multicellular life. The mangrove ecosystem is nutrient limited and without microbial cycling, life in this harsh environment would likely not exist. The mangroves of Southeast Asia are the oldest and most biodiverse of all the planets. They have vital roles helping to prevent shoreline erosion, act as nursery grounds for many marine species and contain significant stocks of sequestered carbon. Despite these recognised benefits and the importance of microbes in these ecosystems, studies examining the mangrove microbiome are scarce, especially in the Southeast Asian biodiversity hotspot. Here we examine the microbiome of Avicenia alba and Sonneratia alba and identify a core microbiome of 81 taxa, a further eight taxa (Pleurocapsa, Tunicatimonas, Halomonas, Marinomonas, Rubrivirga, Altererythrobacte, Lewinella, and Erythrobacter) were found to be differentially abundant suggesting key roles in this microbiome, with the identified dimethylsulfoniopropionate (DMSP) metabolisers having important functions in these habitats. The majority of those identified are involved in nutrient cycling or involved in the production of compounds that promote host survival. Increasingly, blue carbon and nature-based solutions to climate change are heralded as viable mitigation steps to limit climate change, however, this is done with little to no consideration of the microbial communities that cycle sequestered carbon in these environments. Here, we examine the microbial communities present in sediment samples taken in close proximity to each tree, sediment samples represent a major sink of atmospheric carbon and understanding how the associated communities will change as climate change advances will become an increasingly important part of carbon stock assessments. Knowing what microbes are presently there is an important first step in this process.
