EcoWB’s Technical Advisor, Dr. Ian Hendy, has helped bring the mysteries of the UK’s underwater forests to life in a stunning new documentary, Forests Beneath the Waves. Commissioned by Natural England and produced by a team of filmmakers led by Dr. Hendy from the University of Portsmouth’s Institute of Marine Sciences (IMS), the film offers a rare and breathtaking look at the kelp forests surrounding the Isle of Wight, Devon, and Cornwall.
Kelp forests are some of the most productive habitats on the planet, supporting a vast array of marine life and playing a crucial role in mitigating climate change. The documentary, now available on YouTube, highlights the importance of these ecosystems and the threats they face.
“When Natural England approached me to make this exciting film, I was thrilled. I immediately realized the significance and impact this could have for policy, protection, and outreach,” said Dr. Hendy. “We encountered everything from beautiful sharks, stunning juvenile rays, mesmerizing cuttlefish, and even tuna fish! The vibrant life in our UK kelp forests rivals that of tropical coral reefs.”
The film captures a hidden world beneath the waves, showing undulate rays and gobies sheltering from predators, a nursehound shark securing her egg, and a seal hunting for food. These forests provide essential nursery grounds and shelter for marine species, while also buffering coastlines from storms, increasing oxygen levels, and absorbing carbon dioxide.
Despite their resilience, kelp forests are under serious threat from warming oceans, pollution, coastal development, and overfishing. Their decline is already being observed in the UK, making conservation efforts—and awareness—more urgent than ever.
“Climate change is a big factor,” said Marina Rees, Marine Higher Officer at Natural England. “I have witnessed the increase of bleached kelp during heat waves, and escalating storms destroying entire parts of kelp forests. In the film, we even captured the crystal jellyfish—normally found in the Pacific—now appearing in UK waters due to rising temperatures.”
With its stunning visuals and powerful message, Forests Beneath the Waves showcases why protecting these ecosystems matters—not just for marine life, but for the planet as a whole.
