Marine debris is a persistent and pervasive threat worldwide including inside marine protected areas (MPAs). To assess marine debris accumulation rates and potential impacts, we counted and evaluated trap, non-trap fishing gear, and non-fishing debris in unprotected areas and MPAs with different management boundary regulations in the Florida Keys (USA). Analyses identified that neither MPA type nor size were strong drivers of debris density and that debris densities were not statistically different between unprotected areas and MPAs. Non-fishing and non-trap fishing gear debris densities were potentially related to unexplored local differences in human behavior, while trap debris density was likely associated with oceanographic forces that transported traps into the MPAs. Overall, our results suggested that the drivers of marine debris accumulation for each debris category were different and may vary with each individual MPA, and that marine debris is not constrained by MPA boundaries.
海洋垃圾是一种全球性的、普遍存在的威胁，包括在海洋保护区内。为了评估海洋垃圾的积累率和潜在影响，我们在佛罗里达群岛（美国）的未保护区和具有不同管理边界规定的海洋保护区内，对陷阱、非陷阱渔具和非渔具垃圾进行了计数和评估。分析表明，无论是海洋保护区类型还是大小，都不是造成垃圾密度的主要因素，而且未保护区和海洋保护区之间的垃圾密度没有统计学差异。非渔具和非陷阱渔具垃圾密度可能与人类行为的未知局部差异有关，而陷阱垃圾密度可能与将陷阱运入海洋保护区的海洋力量有关。总的来说，我们的结果表明，每种垃圾类别的海洋垃圾积累的驱动因素是不同的，并且可能因每个单独的海洋保护区而异，而且海洋垃圾不受海洋保护区边界的限制。
