Reefscapers History

Reefscapers is an independent marine consultation company that aims to restore coral reefs in the Maldives and worldwide. It was founded by Thomas Le Berre and Marie Saleem, a couple passionate about the underwater world and in love with the beauty and mystery of coral reefs.

Thomas created ‘Seamarc’ in 2000, now known as ‘Reefscapers’. He first performed audits and environmental impact assessments for multiple projects in the Maldives, from port development to coastal management. However, Thomas quickly realised that coral reefs were being negatively impacted by development and climate change, so decided to explore methods to restore and protect them.

Following several years of researching various techniques, Thomas developed the revolutionary and pioneering coral frame technique that has now been adopted by various coral conservation groups worldwide.

Reefscapers Expansion

Thomas first partnered with Four Seasons in 2006, developing coral propagation programs at Landaa Giraavaru and Kuda Huraa. Marine activities were developed, and our Marine Discovery Centres were among the first to open in the Maldives, including the pioneering Fish Lab (set up to breed Maldivian Clownfish in captivity).

Increased guest awareness grew our coral frame sponsorship program, which includes regular monitoring and photography of the growing coral frames, to expand into the largest of its type in the world.

Over the years, Reefscapers has developed partnerships with various resorts around the Maldives, and we have now transplanted more than 8000 coral frames into the ocean, representing half a million individual coral fragments. We have an international team of up to 20 full-time marine biologists resident in the Maldives, with expertise in coral propagation, marine aquaculture, turtle conservation & medicine.

In 2020, Reefscapers partnered with Sheraton Maldives and the Maldivian Government to create what is now believed to be the largest man-made coral structure in the Maldives. For 2 months, Thomas and a team of dedicated marine biologists worked tirelessly to relocate healthy corals from Gulhi Falhu industrial zone, to give them a second chance on our coral frames (photo).

Reefscapers is looking to expand in the Maldives and grow its network internationally, to keep restoring coral reefs around the world, giving future generations the chance to see the beauty of coral reefs with their own eyes.

As well as running the company (now known as ‘Reefscapers’), Thomas is actively and passionately involved in each project, and continues to develop unique cutting-edge solutions to solve pressing environmental issues.

Kate Sheridan (marine biologist)

Kate has always been passionate about wildlife and loves being near the ocean. After studying Geography BSc in the UK, she moved to South Africa and studied for her MSc in Conservation Biology at the University of Cape Town. For her thesis, she investigated water user’s perceptions of shark management and shark risk, which she later published in the journal, Marine Policy.

Originally from the UK, Kate has spent a lot of time in South Africa, working with a wide variety of wildlife from sharks to hyenas to rhinos. She co-hosts a wildlife and conservation podcast called The Biome Podcast, runs her own conservation blog and works as a freelance content creator.

Having spent 6 months working in the Maldives with Reefscapers focusing on marine communications, Kate was thrilled to accept a full-time position as resident Marine Biologist. She now manages the coral propagation program at Sheraton Maldives, restoring the reefs, monitoring coral growth, and running other marine conservation activities at the Resort.

Katelyn Hegarty-Kelly (assistant marine biologist)

Originally from Ireland, Katelyn has gained a huge passion for marine life through many travel experiences growing up. Since the age of 15, she knew she wanted to be a marine biologist with an urge to work in conservation and research. She graduated in Applied Freshwater & Marine Biology from the Atlantic Technological University (ATU), Galway, Ireland. For her final year thesis, she looked at microplastics in the common prawn at Galway Bay. She gained further ATU experience assisting in various microplastic research projects.
In 2021, she founded and co-directs The Ray Project NGO, based in Ireland which is working towards the conservation and awareness of native ray and skate species along the Irish coast.

Having a huge interest and urge to work in coral restoration work, she discovered Reefscapers and was eager to apply for an internship position after graduation. She is delighted to join the team at the Sheraton Resort, where she will assist in running the Adopt-a-Coral program and create content for social media platforms.

Sebastien Stradal (marine consultant)

Sebastien gained a Master’s degree in Marine Biology at the University Montpellier (France). This was the fulfillment of a dream kindled by a passion about the marine world that began at a young age growing up in the coastal area of a small city in West Africa.

Sebastien first started his career as an aquaculture technician, with the opportunity of working with varied marine species and multiple productions in Australia, Europe, SE Asia and the Caribbean. More adventures unfolded, as Sebastien went to work as a fish-inspector in the Antarctic and in the Indian Ocean, on fishing vessels targeting tuna and Patagonian toothfish.

After a year at sea, Sebastien went to Thailand to develop coral reef restoration projects for resorts for two years. He then went for one last trip to the Kerguelen Islands as part of a scientific expedition to study the marine life population, before settling down as the Manager of the Marine Discovery Centre, based at Landaa Giraavaru (2014 to 2017).

Always looking for a new challenge, since 2018 Sebastien has been working to protect the marine environment as a Reefscapers Consultant, and continues to develop projects in the Maldives and internationally.

Preston McMahon (coral projects and digital content)

Preston received a master’s degree in Landscape Architecture at the University of Minnesota (USA). He grew up in a rural agricultural community where he saw how human practices have a large impact on distant marine environments. His degree communicated the disconnect we have with our environment at local and global scales.

Preston’s thesis focused on coral reefs: their beauty and degradation. He combined his love for the ocean and passion for 3D-modelling to create further awareness of our underwater ecosystems using virtual and augmented reality; bridging a communication gap for those who may otherwise not have access to the marine environment.

Upon graduation, Preston was excited to move to the Maldives (2022) to continue his passion for ocean communication with Reefscapers. He develops innovative graphical solutions to increase awareness of Reefscapers projects. By sharing his passions and educating about the importance of coral reefs, he hopes to promote restoration and a move towards more sustainable practices in the Maldives.

In 2023, Preston joined our team of full-time staff, working on bespoke Reefscapers coral projects in local island communities.
