For centuries, cetaceans (whales, dolphins and porpoises) have been found stranded around the UK coastline.

But the role of human impacts in causing these events remained unclear until the advent of the collaborative ZSL-led UK Cetacean Strandings Investigation Programme (CSIP). The CSIP is contracted by UK Government to investigate stranding events to learn about their causes, and collect data that inform efforts to improve the long-term future of vulnerable marine species in our waters. 

In the 30-year period since its inception, the CSIP has recorded data on over 17,000 cetacean strandings and investigated over 4,500 through systematic and forensic post-mortem examinations.

A wide variety of causes of death have been diagnosed, ranging from bycatch (incidental entanglement in fishing gear), ship-strike and bottlenose dolphin attack, to a condition analogous to decompression sickness in humans.

The CSIP has also carried out extensive research into a range of threats over this period, including impacts from chemical, acoustic and physical pollution and climate change driven shifts in distribution.

During this anniversary event we explored the work of the CSIP in the UK over the last 30 years and discussed what our research reveals about the threats these species face and the state of the wider marine ecosystem.
