This survey contains a series of records of the non-native marine alga, Sargassum muticum, around Wales. Many of the records were obtained during the intertidal phase 1 survey, while others are anecdotal records from both Countryside Council for Wales (CCW) staff and various other recorders surveying the shoreline for both work or recreationally. The dataset has been fully validated. All grid references have been cross-referenced against site name. The majority of records were recorded by specialists.
