Seal Usage Maps
Marine Scotland has commissioned the Sea Mammal Research Unit at the University of St Andrews to provide updated maps showing the distribution of grey and harbour seals around the UK.
These 'usage' maps are produced by looking at movement patterns from electronically tagged seals. The resulting patterns of usage are scaled to population levels using data collected in aerial survey counts at haul out sites, to produce estimates of mean density (seals per 5x5 km grid cells).
