Effects of seasonal variation on the characteristics of stranded marine debris within Rambut Island Wildlife Reserve, Indonesia
Summary
A survey of marine debris on the beaches and mangroves of Pulau Rambut Wildlife Reserve in Indonesia found that plastic dominated debris loads, with single-use plastics like styrofoam, sachets, and packaging most prevalent. The study provides baseline data showing that even protected wildlife areas accumulate substantial plastic pollution, underscoring the need for upstream plastic reduction to protect sensitive coastal and mangrove ecosystems.
Monitoring and assessing the items stranded on shorelines is a crucial step in addressing the threat posed by marine debris to our ocean. The objective of this study is to examine the occurrence and categorize marine debris that accumulates on the beach and mangrove area of Pulau Rambut Wildlife Reserve from the transitional season 2 to the rainy season. The abundance of marine debris is significant in transitional season 2. There is no significant difference between different seasons. The dominant form of debris among all macrodebris categories during transitional season 2 was plastic, accounting for 46.38% of the total. Single-use plastics like styrofoam, shoes, sandals, gloves, plastic wrap, and plastic sachets were found to be the most common types of large-scale plastic debris, comprising 60% of total macroplastic debris. The debris found on Rambut Island is believed to originate from debris carried by rivers that flow into Jakarta Bay. The presence of seasonal winds, currents, waves, and tides further contribute to the accumulation of debris in this area.

Abundance and characterization of microplastic pollution in the wildlife reserve, Ramsar site, recreational areas, and national park in northern Jakarta and Kepulauan Seribu, Indonesia
This is the first study to measure microplastic pollution in sediments across protected areas near Jakarta, Indonesia, including a wildlife reserve, a Ramsar wetland site, and a marine national park. Microplastics were found at all locations, with higher concentrations closer to human activity and during the dry season. The results suggest that even designated conservation areas are not spared from microplastic contamination.
Spatial distribution of marine debris in mangrove ecosystem of Pantai Indah Kapuk, Jakarta
Researchers surveyed marine debris in the mangrove ecosystem of Pantai Indah Kapuk in Jakarta, finding that plastic items made up 77.7% of all macro debris followed by styrofoam at 18.1%. Microplastics were also assessed in sediments, establishing baseline contamination data for this urban mangrove system.
Seasonal variation in plastic litter pollution in mangroves from two remote tropical estuaries of the Colombian Pacific
Researchers found that plastic litter in two remote Colombian Pacific mangrove estuaries was dominated by microplastics, with higher abundances during high-rainfall seasons in both surface waters and sediments, and foams and fragments being the most common types.
Distribution of Marine debris in Coral Reef Ecosystems on Mules Island, Sawu Marine National Park
This study mapped the distribution and types of marine debris in the coral reef ecosystem around Mules Island in Sawu Marine National Park, Indonesia. Plastic waste was the dominant debris type, threatening the biodiversity and ecosystem services of this protected marine area. The findings highlight the need for better waste management in coastal communities adjacent to protected marine parks.
The abundance of Plastic Marine Debris on Beaches in Ambon Bay
Researchers measured plastic marine debris — including large microplastics, mesoplastics, and macroplastics — on two beaches in Ambon Bay, Indonesia. The study provides baseline data on plastic pollution levels in a region with growing coastal populations and limited plastic waste management infrastructure.
