Record numbers of three dolphin species have been recorded off Scotland’s west coast by the Hebridean Whale and Dolphin Trust.

In the course of 2016 the conservation charity’s marine research expeditions recorded 2,303 individual common dolphins, 42 bottlenose dolphins and 94 Risso’s dolphins – the highest number recorded for each species.

Dr Lauren Hartny-Mills, Science Officer of Hebridean Whale and Dolphin Trust, said: “The reasons for the high number of sightings of these charismatic dolphin species – and the broader effects on the marine environment and other species – remain unclear. But the intriguing findings highlight the importance of on-going monitoring and research – to strengthen our understanding of what is taking place in Hebridean waters, and to ensure well-informed conservation action.”

Average annual figures documented over the previous 14 years were 463 individual common dolphins, 14 bottlenose dolphins and 12 Risso’s dolphins.

The latest findings were made in a research season lasting from May to October 2016, with volunteers working with marine scientists on visual surveys and acoustic monitoring with underwater microphones or hydrophones, and identifying individual cetaceans through photography.

Alison Lomax, Director of Hebridean Whale and Dolphin Trust, said: “The impressive range of species documented in our at-sea surveys last year is a powerful reminder that Scotland’s west coast ocean environment is home to remarkable marine life. Long-term scientific studies of this globally-important habitat and its inhabitants are crucial if we are to ensure a secure future for the Hebrides’ spectacular cetaceans.”
