This study of aviation-related recreation loss shows that a survey primarily aimed at collecting information on invasive species’ pathways can also be used to estimate changes in pathway-related ecosystem services. We present a case study for Elodea spp. (elodea), Alaska’s first known aquatic invasive plant, by combining respondents’ stated pre-invasion actual flights with stated post-invasion contingent behavior, plane operating costs, and site quality data. We asked pilots about the extent of continued flights should destinations become invaded and inhibit flight safety. We estimate a recreation demand model where the lost trip value to the average floatplane pilot whose destination is an elodea-invaded lake is US$185 (95 % CI $157, $211). Estimates of ecosystem damages incurred by private actors responsible for transmitting invaders can nudge actors to change behavior and inform adaptive ecosystem management. The policy and modeling implications of quantifying such damages and integration into more complex models are discussed.

漂流到北极淡水的旅行者：私人航空和水生入侵造成的娱乐损失。

这项与航空有关的休闲损失的研究表明，一项主要旨在收集有关入侵物种路径的信息的调查也可以用于估计与路径有关的生态系统服务的变化。我们为Elodea提供一个案例研究spp。（elodea），阿拉斯加的第一个已知水生入侵植物，通过将受访者的入侵前陈述的实际飞行数与入侵后的或有行为，飞机运营成本和站点质量数据相结合而得出。我们向飞行员询问了如果目的地被侵犯并妨碍飞行安全的情况，继续飞行的范围。我们估计了一个娱乐需求模型，其中目的地为遭受伊罗达河入侵的水上飞机驾驶员的平均出行损失为185美元（95％CI $ 157，$ 211）。负责传播入侵者的私人行为者对生态系统造成的破坏的估计值可以推动行为者改变行为并为适应性生态系统管理提供信息。讨论了量化此类损害并将其整合到更复杂的模型中的政策和建模含义。
