The global extent of marine protected areas (MPAs) is increasing as nations strive to meet UN conservation targets, yet non‐native species (NNS) are a critically overlooked stressor that threatens MPA conservation goals. Despite evidence that marine NNS affect protected species and habitats, there is limited understanding of the pervasiveness of this threat and the extent to which resource managers are responding to it. We disseminated a questionnaire targeting MPA practitioners and scientists to determine the overall state of knowledge and perception of NNS in MPAs. We received 151 responses from individuals in 47 countries and territories, including a total of 116 MPAs of which 73 were reported to have NNS present. Although NNS are a prevalent issue in MPAs and are the subject of some monitoring, management, and research, preventative measures are largely absent, so that more focused attention on NNS will be required to achieve conservation goals.

非本地物种是海洋保护区的全球性问题

随着各国努力实现联合国的保护目标，全球海洋保护区（MPA）的范围正在增加，但非本地物种（NNS）是一个受到严重忽视的压力源，威胁着MPA的保护目标。尽管有证据表明海洋NNS会影响受保护的物种和栖息地，但是对于这种威胁的普遍性以及资源管理者对这种威胁的响应程度的了解仍然有限。我们分发了一份针对MPA从业者和科学家的问卷，以确定MPA中NNS的整体知识和知觉状态。我们收到了来自47个国家和地区的151条回复，其中包括116个MPA，其中73个被报告存在NNS。尽管NNS是MPA中普遍存在的问题，并且是某些监视，管理和研究的主题，
