Litter is an especially large and costly problem in unsupervised high-use recreational areas. This study investigated procedures to induce visitors to remove litter from an unsupervised U.S. Forest Service area in which signs attached to two litter stations instructed people to pick up and deposit litter. A small sum of money or chances on a larger sum given for participation usually resulted in more bags of litter being picked up per week. Although only a small proportion of the area's users participated in the project, ground surveys indicated the areas sampled were somewhat freer of litter during the payment condition. The results suggest that small monetary rewards may be a promising approach to litter control in unsupervised as well as supervised areas.
垃圾在无人监管的高使用率娱乐区是一个特别大且昂贵的问题。本研究调查了一种程序，该程序旨在促使游客从无人监管的美国林务局区域清理垃圾，该区域的两个垃圾站附有指示牌，要求人们捡起并存放垃圾。为参与活动提供少量金钱或获得更大金额的机会通常会导致每周捡起更多袋垃圾。尽管只有一小部分区域的使用者参与了该项目，但地面调查表明，在付费条件下，抽样区域的垃圾量有所减少。结果表明，少量金钱奖励可能是无人监管和监管区域控制垃圾的一种有前途的方法。
