Abstract

Invasive species are an increasing source of economic loss, costing nations billions of dollars annually. Significant financial resources are spent to manage invasive species, but few comprehensive syntheses of the economic expenditures associated with this management effort exist. As a relatively affluent developed country, the United States should serve as a model of how to both manage invasive species and, more critically, understand the economic costs of doing so. To begin understanding the scale of expenditures on invasive species in the U.S., our goal was to quantify spending on invasive species management at the state level. We contacted natural resource management officials from all 50 states following a standardized protocol. While 47 of the 50 states provided expenditures for at least one of the five years requested (2017–2021), the distribution of expenditures by state varied dramatically, suggesting that actual expenditures might be much higher than those reported. While most states shared annual expenditures, they varied by an order of magnitude from $28,370 for Connecticut to $118,695,389 for Washington. Specifically, a widespread lack of careful and consistent expense tracking and coordination within and between states made clear and correct evaluation difficult. While the expenditures we obtained are almost certainly a significant underestimate, they also represent a serious lack of accounting at a state level. Hence, better tracking and coordination, within and between states, will be critical to handle the ongoing invasive species crisis.

囊中羞涩:美国各州用于入侵物种管理的开支杂乱无章、缺乏协调且不完整
入侵物种造成的经济损失越来越大,每年给各国造成数十亿美元的损失。美国花费了大量财政资源来管理入侵物种,但很少有对与这种管理努力相关的经济支出进行全面综合的报告。作为一个相对富裕的发达国家,美国应该成为管理入侵物种的典范,更重要的是,美国应该了解管理入侵物种的经济成本。为了开始了解美国在入侵物种方面的支出规模,我们的目标是量化各州在入侵物种管理方面的支出。我们按照标准协议联系了全美 50 个州的自然资源管理官员。虽然 50 个州中有 47 个州提供了所要求的五年(2017-2021 年)中至少一年的支出,但各州的支出分布差异巨大,这表明实际支出可能远高于报告的支出。虽然大多数州都共享了年度支出,但从康涅狄格州的 28,370 美元到华盛顿州的 118,695,389 美元,各州的支出相差悬殊。具体而言,由于各州内部和州与州之间普遍缺乏细致、一致的支出跟踪和协调,因此很难进行清晰、正确的评估。尽管我们获得的支出几乎肯定被严重低估,但它们也代表了州一级会计工作的严重缺失。因此,更好地跟踪和协调各州内部和各州之间的情况,对于应对当前的入侵物种危机至关重要。

期刊介绍: Biological Invasions publishes research and synthesis papers on patterns and processes of biological invasions in terrestrial, freshwater, and marine (including brackish) ecosystems. Also of interest are scholarly papers on management and policy issues as they relate to conservation programs and the global amelioration or control of invasions. The journal will consider proposals for special issues resulting from conferences or workshops on invasions.There are no page charges to publish in this journal.
