Invasive plants are expanding their ranges due to climate change, creating new challenges for invasive species management. Early detection and rapid response could address some nascent invasions, but limited resources make it impossible to monitor for every range-shifting species. Here, we aimed to create a more focused watch list by evaluating the impacts of 87 plant species projected to shift into northern New England (the states of Maine, New Hampshire, and/or Vermont). We used the Environmental Impact Classification for Alien Taxa (EICAT) protocol to evaluate all ecological impacts reported in the scientific literature, scoring ecological impacts from 1 (minimal concern) to 4 (major) depending on the level of reported impact. For each species, we also recorded any reported impacts on socioeconomic systems (agriculture, human health, or economics) as “present.” We found 24 range-shifting species with impacts on ecological communities, of which 22 have reported impacts in ecosystems common to northern New England. Almost all of these species also had impacts on socioeconomic systems and were available for purchase at ornamental plant retailers or online. Thus, these species can be considered high risk to northern New England with climate change based on their large negative impacts and potential to arrive quickly with deliberate human introduction. Our study demonstrates the use of impact assessments for creating targeted priority lists for invasive species monitoring and management.

识别可能随着气候变化转移到新英格兰北部的高影响入侵植物

由于气候变化,入侵植物正在扩大其范围,为入侵物种管理带来了新的挑战。早期发现和快速反应可以解决一些新生的入侵,但有限的资源使得不可能监测每一个范围转移的物种。在这里,我们旨在通过评估预计将转移到新英格兰北部(缅因州、新罕布什尔州和/或佛蒙特州)的 87 种植物物种的影响来创建一个更有针对性的观察名单。我们使用外来类群的环境影响分类 (EICAT) 协议来评估科学文献中报告的所有生态影响,根据报告的影响程度对生态影响从 1(最小关注)到 4(主要)进行评分。对于每个物种,我们还记录了对社会经济系统(农业、人类健康、或经济学)作为“现在”。我们发现了 24 个对生态群落有影响的范围转移物种,其中 22 个报告了对新英格兰北部共同生态系统的影响。几乎所有这些物种也对社会经济系统产生影响,并且可以在观赏植物零售商或网上购买。因此,这些物种可以被认为是新英格兰北部气候变化的高风险,因为它们具有巨大的负面影响,并且有可能通过有意的人类引入而迅速到达。我们的研究展示了使用影响评估为入侵物种监测和管理创建有针对性的优先列表。几乎所有这些物种也对社会经济系统产生影响,并且可以在观赏植物零售商或网上购买。因此,这些物种可以被认为是新英格兰北部气候变化的高风险,因为它们具有巨大的负面影响,并且有可能通过有意的人类引入而迅速到达。我们的研究展示了使用影响评估为入侵物种监测和管理创建有针对性的优先列表。几乎所有这些物种也对社会经济系统产生影响,并且可以在观赏植物零售商或网上购买。因此,这些物种可以被认为是新英格兰北部气候变化的高风险,因为它们具有巨大的负面影响,并且有可能通过有意的人类引入而迅速到达。我们的研究展示了使用影响评估为入侵物种监测和管理创建有针对性的优先列表。
