This dataset was collected in support of a study on the resilience of restored seagrass (Zostera marina) meadows to marine heatwave exposure in North Wales, United Kingdom (Thomas et al., 2026). It provides polygon-vector spatial data, in shapefile format, delineating the boundaries of the planted seagrass areas, derived from dGPS-surveyed vertices recorded at four restoration sites in North Wales between February 2023 and April 2024.
