In the Welsh part of the Irish Sea, a method was developed for assessing the sensitivity of different seabed habitats to existing fishing activities, across a range of potential fishing intensities. The resistance of 31 habitats and their associated biological assemblage to damage by 14 categories of fishing activity were assessed along with the rate at which each habitat would recover following impact (resilience). Sensitivity was scored based on a combination of the resistance of a habitat to damage and its subsequent rate of recovery. The assessments were based, wherever possible, on scientific literature, with expert judgement used to extrapolate results to habitat and gear combinations not directly examined in the published literature. The resulting sensitivity matrices were then subject to further peer review at a series of workshops. Following consensus on the habitat sensitivity, these data were combined with the most resolved sea-floor habitat maps. These habitat sensitivity maps can help inform the development of site-specific management plans, as well as having a place in spatial planning and aiding managers in developing dialogue with other stakeholders. A case study of their application is provided.
在爱尔兰海的威尔士部分，开发了一种方法来评估不同海底生境对现有捕捞活动的敏感性，涵盖了一系列潜在的捕捞强度。评估了 31 种生境及其相关生物组合对 14 类捕捞活动造成的损害的抵抗力，以及每种生境在受到影响后恢复的速度（恢复力）。敏感性是根据生境对损害的抵抗力及其随后的恢复速度的组合来评分的。评估尽可能基于科学文献，利用专家判断将结果推断到未在已发表文献中直接检查的生境和渔具组合。然后，将生成的敏感性矩阵在一系列研讨会上进行进一步的同行评审。在对生境敏感性达成共识后，这些数据与最详细的海底生境地图结合使用。这些生境敏感性图可以帮助制定特定地点的管理计划，同时在空间规划中占有一席之地，并帮助管理者与其他利益相关者进行对话。提供了一个应用案例研究。
