In the face of climate change, biodiversity loss, and the growing threats to our oceans, the concept of rewilding is emerging as an approach to restoring ecosystems to their natural states.
At Oyster Heaven, we believe that rewilding – or seawilding – the ocean through the restoration of oyster reefs is a key solution to help nature heal itself. By strategically restoring oyster reefs in specific locations, these reefs act as marine biodiversity hotspots encouraging species to return and thrive.

As climate change intensifies, coastal regions around the world are facing increasing threats from rising sea levels, storm surges, and coastal erosion. Traditional artificial solutions like seawalls and breakwaters are often expensive, disruptive to marine habitats, and ultimately not sustainable in the long term.
At Oyster Heaven, we believe in turning to nature to support the best engineering solutions.

One of the most promising approaches we’ve identified is the regeneration of oyster reefs as living breakwaters to protect our coasts.

The concept of planetary boundaries, introduced by scientists in 2009, outlines nine critical limits within which humanity can safely operate to maintain Earth’s stability.

At Oyster Heaven, we are tackling these challenges by restoring oyster reefs at scale – a vital solution for the health of marine ecosystems. Restoration of these habitats tackles many of these issues simultaneously

While well-run CSR programs do aim to make businesses more ethical and environmentally responsible, initiatives to support nature should not be relegated to CSR alone. Such investments should be treated as core operational costs necessary for a company’s survival, risk management, and profitability. It’s an essential cost of doing business.

Marine regeneration is an essential mission aimed at restoring our oceans back into the productive and healthy ecosystems they once were. Among the many challenges faced by conservationists, one concept that often quietly impacts efforts is the ‘shifting baseline syndrome’, first considered by fisheries scientist Daniel Pauly. This term refers to a phenomenon where each generation of scientists and ocean users accepts the condition of the environment they first encounter as the norm, or baseline, even though this baseline may have already been significantly degraded compared to previous generations.

tarting off her career on gut bacteria research in Cape Town, Dr. Natacha Juste-Poinapen took a fascinating path applying her chemical engineering expertise to the marine environment, a place close to her heart, having grown up near the ocean. As the first hire at Oyster Heaven, Natacha focuses on enhancing oyster regeneration and evaluating restoration site suitability by studying the microbiological components of oyster reefs. She collaborates with DTU Aqua in Denmark, and Deltares and NIOZ in the Netherlands, bringing unique insights to our ambitious goal of restoring historic oyster reefs.

As we work hard to implement our approach to oyster reef restoration in the Netherlands and the UK, we are also filling up our project pipeline to initiate even more reefs to steadily bring back the lost oyster reefs in our European waters and beyond. With our workload growing, our team expanding, and our outreach broadening, it’s time to introduce the dedicated individuals who’ve been working tirelessly behind the scenes. Let’s begin with our founder, George, the visionary driving force behind it all…

In the world of marine conservation, the search for effective materials to aid restoration is a never-ending exploration. For oyster reefs specifically, the need for a suitable substrate is the key in achieving reef revitalisation. Among the many materials, clay stands out as a tested solution which has led us at Oyster Heaven to use it as the preferred material to kick start large-scale oyster reefs.
