Principal Salmon Rivers of England and Wales

There are 49 rivers in England and 31 rivers in Wales that regularly support salmon, although some of the stocks are very small and support minimal catches. Of these, 64 rivers were designated ‘principal salmon rivers’ on the basis of the prospect of annual rod catches of at least 50 fish around the time (~1996) of the development of Salmon Action Plans (SAPs*). These data are recreated from SALMON STOCKS AND FISHERIES IN ENGLAND AND WALES, 2021 figure 1 using OS Open Rivers. Attributes include if a river has a SAP and if it is designated as a Special Area of Conservation (SAC) in which salmon must be maintained or restored to favourable conservation status (SALMON STOCKS AND FISHERIES IN ENGLAND AND WALES, 2021 Table 1). These data are intended for visualisation only and should not be used for statutory purposes or connectivity modelling. *Salmon Action Plans in Wales are now referred to as ‘Know Your Rivers’ reports.英格兰共有49条、威尔士共有31条河流常年栖息有鲑鱼种群，不过部分种群规模极小，仅能支撑极少量捕捞。其中64条河流在鲑鱼行动计划（Salmon Action Plans, SAPs*）制定前后（约1996年），以年竿钓捕捞量至少可达50尾的预期为依据，被划定为"主要鲑鱼河流"。本数据集基于OS Open Rivers数据源，复刻自《2021年英格兰与威尔士鲑鱼种群及渔业》中的图1。数据集属性包括河流是否配有鲑鱼行动计划（Salmon Action Plans, SAPs），以及是否被划为特殊保护区（Special Area of Conservation, SAC）——该类保护区要求维持或恢复鲑鱼种群至有利保护状态（数据来源：《2021年英格兰与威尔士鲑鱼种群及渔业》表1）。本数据集仅用于可视化展示，不得用于法定用途或连通性建模。*注：威尔士地区的鲑鱼行动计划现更名为"了解你的河流"（Know Your Rivers）报告。
