Marine scientists have reported a sharp rise in whale and dolphin strandings across Scotland, describing the increase as “exponential” and raising concern for the health of marine ecosystems. According to the Scottish Marine Animal Stranding Scheme, this summer has seen record numbers of strandings, including several high-profile incidents in Orkney and along the north-west coast.

While some events can be explained by natural factors, experts say the overall pattern is troubling. Speaking to The Guardian, marine ecologist Dr Conor Ryan noted that causes could range from shifting prey availability and disease to underwater noise and climate-driven changes in habitat. In Orkney, where a pod of pilot whales became trapped, experts admitted the exact reasons were “almost impossible to figure out”.

The Scotsman reported that conservationists fear some populations could face long-term decline if strandings continue at current levels. Many of the affected species are already vulnerable, including pilot whales, dolphins and minke whales.

The rise has triggered debate about whether cumulative human pressures, including fishing activity, shipping noise and chemical pollution, are compounding natural stresses. Responders on the ground say they are stretched thin, as incidents require large teams of volunteers and often end in fatalities despite rescue attempts.

Officials are urging continued monitoring and further research to establish clearer links between human activity and the surge in strandings. Conservation groups argue that precautionary measures, particularly around noise and disturbance, should be strengthened before more evidence is lost with each event.
