Invasive alien species (IAS) constitute a trans- and intracontinental challenge. With this article, we exemplify obstacles met during the implementation of the Regulation (EU) No. 1143/2014 against IAS and comparatively assess them through two case studies from two Member States, Austria and Romania, via qualitative content analysis. Challenges are identified, analyzed, and discussed based on interviews with stakeholders from both countries in the view of the three main intervention types within this Regulation: prevention, early detection, and rapid eradication and management. The obstacles, which the two Member States met, are related to creating, updating, and maintaining the Union List and to the distribution of competences, which influence the national and subnational cooperation and coordination. Financial resources, custom controls, national legislation, and awareness influence the implementation of the IAS Regulation too. This research contributes to improving knowledge about numerous details of the implementation and enforcement of this IAS-Regulation to make them more feasible, not just for scientists, but also for decision- and policymakers, business owners, and other stakeholders.

可持续发展和外来入侵物种：欧盟法规的实施挑战

外来入侵物种 (IAS) 构成跨大陆和大陆内的挑战。在本文中，我们举例说明了在实施针对 IAS 的第 1143/2014 号条例 (EU) 期间遇到的障碍，并通过定性内容分析，通过来自两个成员国（奥地利和罗马尼亚）的两个案例研究对这些障碍进行了比较评估。根据本法规中的三种主要干预类型：预防、早期发现以及快速根除和管理，根据与两国利益相关者的访谈，识别、分析和讨论了挑战。两个成员国遇到的障碍与创建、更新和维护联盟列表以及权限分配有关，这会影响国家和地方的合作与协调。财务资源、自定义控制、国家立法和意识也会影响 IAS 法规的实施。这项研究有助于提高对本 IAS 法规实施和执行的众多细节的了解，使它们变得更加可行，不仅对科学家，而且对决策者和政策制定者、企业主和其他利益相关者也是如此。
