The aim of this study is to provide a general overview of the economic impacts associated with vertebrate invasive species (VIS) in the United States and suggests a methodology for differentiating types of damage. We identify a general framework for categorizing VIS damage that separates this damage into three main categories: destruction, depredation, and disease. We then examine how this framework fits into current published estimates of damage and management costs. Economic impacts associated with feral swine damage and management are plentiful enough to warrant separate treatment from other VIS and are observed in all three categories. For all VIS examined in this study, damage estimates associated with destruction provide the most evaluations of VIS impacts, especially destruction of crops. Evaluations of the losses associated with depredation are largely absent from the literature. We find that while published studies have estimated substantial economic impact associated with VIS, the current state of the literature focusing on VIS frequently fails to address all of the categories of damage, is difficult to compare or replicate, and is unsuited for extrapolation to nation-wide estimates of damage.

本研究的目的是提供与美国脊椎动物入侵物种 (VIS) 相关的经济影响的总体概述，并提出一种区分损害类型的方法。我们确定了一个对 VIS 损害进行分类的通用框架，该框架将这种损害分为三个主要类别：破坏、掠夺和疾病。然后，我们研究了该框架如何适应当前公布的损害和管理成本估计。与野猪损害和管理相关的经济影响足以保证与其他 VIS 分开处理，并且在所有三个类别中都可以观察到。对于本研究中检查的所有 VIS，与破坏相关的损害估计提供了对 VIS 影响的最多评估，尤其是对农作物的破坏。文献中基本上没有对与掠夺相关的损失进行评估。我们发现，虽然已发表的研究估计了与 VIS 相关的重大经济影响，但目前关注 VIS 的文献经常无法解决所有类别的损害，难以比较或复制，也不适合推断国家广泛的损失估计。
