NatureScot Research Report 1143 - Aerial survey of harbour (Phoca vitulina) and grey seals (Halichoerus grypus) in Scotland in August 2017: the Western Isles, part of West Scotland and part of East Scotland
This report presents the results of aerial counts of harbour seals and grey seals during August 2017 along sections of the Scottish coastline. The results suggest that numbers of harbour seals on the west coast of Scotland and Western Isles remain stable or are increasing. In marked contrast, the numbers of harbour seals on the east coast of Scotland generally remain at low levels, with a historically low count in both the Dornoch Firth, and the Firth of Tay and Eden Estuary. Further surveys have been undertaken in 2018 and are proposed for August 2019.
