No Trees No Seas: Connecting Forests and Oceans

On a crisp, sunny September morning, we ventured deep into Cornwall’s woodlands at the beautiful Cabilla Cornwall to join partners, conservationists and nature enthusiasts for Where the Trees Meet the Seas. This inspiring day, hosted by Plant One Cornwall, was more than a celebration of shared environmental achievements. It was a powerful reminder that the landscapes we cherish and the oceans we depend on are not separate worlds, but deeply connected parts of one living system.

The event served as both a thank-you and a rallying cry, marking the launch of Plant One Cornwall’s No Trees No Seas campaign. This initiative draws on a scientific review by Dr Benjamin Phillips for the Woodland Trust. Its message is clear: caring for our forests can also help to protect our seas.

The Hidden Connection Between Forests and Oceans

Healthy forests play an important part: they help regulate water flow, reduce soil and pollution run-off, and ease pressure on drainage systems. Together, these functions can help support healthier marine ecosystems.

The relationship goes deeper still. Examples from regions including Japan and Canada suggest that reforesting coastal areas can support fish populations, kelp forests, seagrass beds and plankton. Just as trees nurture the seas, the oceans return the favour: salmonids and seabirds, for example, can transport nutrients that support forest health. This beautifully complex system of give and take is at risk if we do not care for both environments.

A Day of Discovery and Hope

The day itself was a celebration of collaboration and shared purpose. Attendees explored the newly planted temperate rainforest area, joined guided woodland walks and listened to engaging talks from environmental specialists. Merlin from Cabilla Cornwall guided us on a tour of the woodland restoration, explaining the practical conservation work taking place on the site.

At the heart of it all was a simple but powerful truth: by restoring lost woodland, we can also help to support the seas surrounding our island.

Plant One’s No Trees No Seas Campaign

No Trees No Seas is a campaign designed to raise awareness, foster collaboration and encourage woodland restoration across Cornwall and beyond. Its work includes sharing the science, creating educational content and building partnerships with landowners and environmental organisations.

Plant One Cornwall and the Celtic Rainforest

The work of Plant One Cornwall has always been rooted in community. Through its efforts, local people can take part in tree-planting events, landowners receive expert guidance on woodland restoration, and businesses can contribute to biodiversity projects on their sites or nearby land. Every tree planted is a step towards restoring lost woodland, including the ancient Celtic rainforest, and bringing greater balance to our ecosystems.

Looking Ahead

Where the Trees Meet the Seas was a day filled with hope, knowledge and a deep sense of shared responsibility. As we left the woodland that afternoon, we carried with us a renewed understanding of how interconnected our world truly is and how much can be achieved when we work together.

At Whistlefish, we are proud to support Plant One Cornwall and its continuing projects, which reflect our commitment to protecting the natural beauty of Cornwall and beyond. After all, the benefits of planting trees reach far beyond the woodland, helping to create a healthier place where forests and oceans can thrive side by side.
