Dunal plants may affect the patterns of deposition of beach litter. In this study, we aimed at evaluating if Carpobrotus spp. patches may act as a litter trap in coastal dune systems. To do so, we counted the number of macrolitter occurring in both Carpobrotus and control (embryo dune vegetation) patches classifying each item into categories according to the Marine Strategy. Totally, we observed a significant difference between litter trapped in Carpobrotus (331 items, representing 62.4% of the total beach litter) and control (199, 37.6%). Plastic fragments were the most trapped items by both Carpobrotus (46.2%) and control patches (47.2%). We also calculated the item co-occurrence, obtaining a random aggregated 'litter community'. The main emerging output is that Carpobrotus patches act as filter in respect to different anthropogenic materials (overall plastics), suggesting that alien plant management actions may contribute to solve beach litter issues as well.
沙丘植物可能会影响海滩垃圾的沉积模式。在这项研究中，我们旨在评估是否加利福尼亚滨藜斑块可以作为沿海沙丘系统中的垃圾陷阱。为此，我们统计了在加利福尼亚滨藜和对照（胚胎沙丘植被）斑块中出现的大垃圾的数量，并根据海洋战略将每个项目分类。总的来说，我们观察到加利福尼亚滨藜（331 个项目，占总海滩垃圾的 62.4%）和对照（199 个，占 37.6%）之间存在显著差异。塑料碎片是加利福尼亚滨藜（46.2%）和对照斑块（47.2%）中捕获最多的垃圾。我们还计算了项目共同出现的情况，得到了一个随机聚集的“垃圾群落”。主要的结果是，加利福尼亚滨藜斑块对不同人为材料（总体塑料）起到了过滤作用，这表明外来植物管理行动也可能有助于解决海滩垃圾问题。
