Average litter abundance onthe Caribbean Sea beaches (1.42 items/m2–12.21 g/m2) and in mangrove forests (1.29 items/m2–28.72 g/m2) were greater than that of the Pacific Ocean beaches (0 items/m2–0 g/m2) and mangroveforests (1.13 items/m2–79.41 g/m2). The most abundant litter material was plastic, which represented93.61% of the total litter content. According to the Clean Coast Index, the sites analyzed in theCaribbean Sea were “Moderate” to “Extremely Dirty”, while those in the Pacific Ocean were “Clean”to “Moderate Dirty”. The Magdalena River is considered the main source of litter on the CaribbeanSea coast, while on the Pacific Ocean coast, litter is essentially associated with the mismanagement ofsolid wastes. This study constitutes a baseline on the litter content of beaches and mangrove forests,and is useful for establishing sound strategies for their protection, restoration and conservation.
