Fishing lines, hooks and nets represent a sub-category of macro-litter potentially entrapping plover birds nesting on sandy beaches. Here, during a winter period, the accumulation pattern of both general beach litter and fishing lines, hooks and nets was analysed on four central Italy beaches. Despite the active monthly litter removal by clean-ups, there was not a decrease in its density during the winter period, due to the continuous accumulation by frequent winter storms. However, the entrapping litter was very low (<2.5 % of the general litter) and appeared directly correlated to the general litter density. Following a DPSIR approach, the general litter can act as an indirect pressure indicator (proxy) of the amount of entrapping litter. Therefore, an increase in general macro-litter should alarm those involved in the conservation of entanglement-sensitive bird species, such as plovers, suggesting that they should implement high-frequency clean-up activities aimed at removing it.
钓线、鱼钩和渔网是大型垃圾的一个子类别，可能会困住筑巢在沙滩上的鸻鸟。在此，在一个冬季期间，对意大利中部四个海滩上的一般海滩垃圾以及钓线、鱼钩和渔网的堆积模式进行了分析。尽管每月通过清理活动积极清除垃圾，但由于冬季频繁风暴的持续堆积，冬季期间其密度并未下降。然而，造成困住情况的垃圾非常少（占一般垃圾的不到2.5%），并且似乎与一般垃圾密度直接相关。遵循驱动力-压力-状态-影响-响应（DPSIR）方法，一般垃圾可作为造成困住情况的垃圾量的间接压力指标（替代指标）。因此，一般大型垃圾的增加应向参与保护对缠结敏感的鸟类物种（如鸻鸟）的相关人员发出警报，这表明他们应开展高频清理活动以清除这些垃圾。
