Pete Raines MBE
CEO
Pete is an entrepreneurial conservationist and CEO focused on pioneering blue carbon initiatives and securing sustainable finance for marine conservation projects. With over 40 years of leadership and award-winning experience in international “Citizen Science” programmes, he was awarded the MBE by HM King Charles for ‘Services to the Protection of Biodiversity’. He has also received accolades including the Worldaware Business Award, Virgin Holidays Responsible Tourism Awards and the British Airways Tourism for Tomorrow Award.
After graduating with a BSc in Marine Biology and Biochemistry from the University of Wales, Pete founded Coral Cay Conservation, leading it for 27 years and developing a sustainable international ‘Citizen Scientist’ approach to reef and rainforest conservation. He later served as interim-CEO of the Caribbean Biodiversity Fund, Director of International Operations at Coral Restoration Foundation International, and CEO of Coral Restoration Foundation Europe, with a focus on partnerships and sustainable finance.
Pete has a long-standing commitment to volunteering, serving as trustee of the Chagos Conservation Trust and as part of the Chagos Environment Network, which successfully lobbied for the designation of the Chagos Marine Protected Area. He also managed two scientific research expeditions to Chagos and currently serves pro bono as a Director of CLEAR Caribbean.
He is a Chartered Geographer (CGeog), Chartered Biologist (CBiol), and a Fellow of the Royal Geographical Society (FRGS), the Royal Society of Biology (FRSB) and the Linnean Society of London (FLS).
Bridget Marshall
CHAIR
Bridget is a senior executive, environmental lawyer, and governance expert, now focused on advancing blue carbon conservation initiatives. With extensive leadership experience across legal, regulatory, and environmental sectors, Bridget has a keen interest in designing robust governance frameworks for marine conservation projects, ensuring transparency, compliance, and long-term sustainability. She has many years experience of developing environmental policy and has worked closely with Scottish Government including a 4 year secondment where she led policy development on environmental regulatory reform.
She is passionate about nature-based solutions to climate change, particularly the protection and restoration of coastal blue carbon ecosystems such as seagrass meadows, mangrove forests, and saltmarshes. She has volunteered with both seagrass and saltmarsh restoration projects in Scotland and was involved in an early mangrove conservation project in Tanzania 30 years ago. Bridget has a unique combination of legal expertise, policy development skills and strategic leadership to drive impactful conservation outcomes through securing funding and building cross-sector partnerships. She is keen to work with others on both policy development and advocacy work for marine conservation and blue carbon.
Cath Downie
TRUSTEE
Cath is a highly experienced project manager and former cybersecurity professional who has transitioned her strategic and risk management expertise into the marine conservation sector. After a distinguished career delivering major government programmes and holding industry-leading cybersecurity certifications, she is now dedicated to advancing projects that protect and restore vital marine ecosystems.
Currently studying International Marine Science at Heriot-Watt University, Cath focuses on the conservation and recovery of blue carbon habitats, particularly seagrass meadows, saltmarshes, and mangrove forests, which play a critical role in carbon sequestration, biodiversity, and coastal resilience. A qualified diver with strong fieldwork experience, she combines scientific understanding with a practical, solutions-focused approach to habitat monitoring and restoration.
She is passionate about driving science-based, measurable conservation initiatives that deliver real environmental impact. With deep experience in governance, compliance, and stakeholder collaboration, Cath brings a rare blend of strategic insight and hands-on capability to marine conservation projects.
Inspired by community-led marine initiatives, she has successfully fundraised for the Scottish Wildlife Trust’s Orkney Snorkel Trail, which promotes awareness of local seagrass habitats and the importance of protecting Scotland’s blue carbon ecosystems.
Holly Greenwood
CONSERVATION INTERN
Holly recently graduated from the University of St Andrews with a First-class BSc (Hons) in Geography and Sustainable Development. Her studies and personal interests have fostered a strong passion for coastal restoration and blue carbon initiatives. Her dissertation, “Quantifying Site-specific Variations of Organic Carbon Storage in Saltmarshes Along the Firth of Forth to Inform Effective Management,” examined how vegetation types influence carbon storage and presented findings through accessible QGIS mapping for communities and policymakers. She was awarded the Edwards Prize for this outstanding fieldwork and research.
Alongside her academic work, Holly volunteers on seagrass, saltmarsh, and oyster restoration projects. She recently completed an internship with the “Muir is Tir” project, focusing on seagrass mapping and community engagement. For the Blue Carbon Trust, Holly applies her research skills to identify impactful projects and charities, producing reports that support its mission, while also strengthening outreach through social media, networking, and community engagement. Her work aims to advance scientific understanding and foster stewardship of vital coastal ecosystems.
