Hebridean sightings soar for harbour porpoises but plunge for basking sharks

Harbour porpoise sightings off Scotland’s west coast increased by 25 per cent in 2014 compared to the previous year while sightings of basking sharks unexpectedly fell by 33 per cent, during marine research expeditions carried out by Hebridean Whale and Dolphin Trust.

 

The charity’s extensive research also revealed dramatic evidence of a shark attack on a member of an endangered group of killer whales thought to be the UK’s only resident population of orca.

Research surveys conducted by the Hebridean Whale and Dolphin Trust (HWDT) during 2013 have identified a remarkably wide range of whale, dolphin and porpoise species – highlighting the need to conserve the rich biodiversity and globally-important marine habitats in western Scotland’s seas.

The latest research is part of HWDT’s unique and long-term monitoring project of cetaceans – whales, dolphins and porpoises – in the Hebrides. With growing concerns over the state of the UK’s seas, and threats to wildlife and ecosystems from human activity, HWDT is calling for volunteers to help continue the pioneering research in 2014.

In total during 2013, HWDT recorded more than 400 encounters with cetaceans and basking sharks, and made almost 1,000 underwater detections of cetaceans using specialist listening equipment.

Kerry Froud, HWDT Biodiversity Officer, said: “The impressive range of species of cetaceans and basking sharks that we have documented this year highlights the wealth of marine life in Scotland’s west coast ocean environment – and the importance of ensuring the continued
