Invasive alien species (IAS) significantly threaten global biodiversity and ecosystem stability. Despite increasing management efforts, a critical knowledge gap existed in understanding commonalities and disparities among national strategies. We analyzed several IAS management lists from 23 countries and the European Union, focusing specifically on vascular plant species within these lists. List composition, characteristics, and associated management measures were analyzed. Key patterns in species prioritization across national lists and intercontinental exchange of invasive alien plants (IAPs) were identified. , , , , were identified as globally recognized threats, being listed by at least 33.3% of analyzed countries and invading five or more continents. Aquatic plants were found to be more frequently included in management lists. A significant directional invasion pattern between the Eastern and Western Hemispheres was identified. Species native to Asia were observed to dominate as significant donors of IAPs across continents. The analysis of list management strategies highlighted substantial gaps in achieving Target 6 of the Kunming-Montreal Global Biodiversity Framework, particularly in species prioritization and inclusion of potential IAPs. In response to these challenges, a tiered classification system for invasive alien species list was proposed, encompassing High-Priority, Watchlist, Potential, and Priority Site categories, which aimed at enhancing management effectiveness by tailoring strategies to different invasion stages and ecological contexts. This study could contribute to understanding global IAPs management strategies and serve as a reference for policymakers and conservation managers to identify priority IAPs and refine management approaches.
外来入侵物种对全球生物多样性和生态系统稳定性构成重大威胁。尽管管理力度不断加大，但在理解各国战略的共性和差异方面仍存在关键的知识空白。我们分析了来自23个国家和欧盟的几份外来入侵物种管理清单，特别关注这些清单中的维管植物物种。分析了清单组成、特征及相关管理措施。确定了各国清单中物种优先排序的关键模式以及外来入侵植物的洲际交换情况。被确定为全球公认的威胁，至少33.3%的分析国家将其列入清单且入侵了五个或更多大洲。发现水生植物更频繁地被列入管理清单。确定了东半球和西半球之间显著的定向入侵模式。观察到亚洲本土物种是各大洲外来入侵植物的主要来源。对清单管理策略的分析凸显了在实现《昆明-蒙特利尔全球生物多样性框架》目标6方面存在的重大差距，特别是在物种优先排序和潜在外来入侵植物的纳入方面。针对这些挑战，提出了一个外来入侵物种清单的分级分类系统，包括高优先级、观察清单、潜在和优先地点类别，旨在通过根据不同的入侵阶段和生态背景调整策略来提高管理有效性。本研究有助于理解全球外来入侵植物管理策略，并为政策制定者和保护管理者确定优先外来入侵植物和完善管理方法提供参考。
