About Bee Ecological
Established in 2020, Bee Ecological Consulting specialises in environmental and social safeguards for sustainable development in island and coastal contexts. Our work combines field ecology, geospatial analysis and stakeholder engagement to produce outputs that inform policy and management.
We deliver national-scale assessments, monitoring frameworks and management plans for government agencies, conservation trusts, international donors and the private sector. Recent assignments include national monitoring protocols, a national coral reef status report, protected-area management plans and biodiversity assessments for environmental impact assessments.
Services
Field science, mapping and planning for island and coastal projects, from baseline surveys to management plans.
Geospatial analysis and remote sensing
GIS mapping, drone surveys, photogrammetry and spatial modelling for planning, habitat classification and climate resilience.
Environmental safeguards and resilience planning
Environmental risk assessment, impact prediction, mitigation frameworks, and management plans for protected and sustainable-use areas.
Stakeholder consultation and community engagement
Participatory consultation, workshop facilitation, co-management support and citizen-science programmes.

Team
Two marine biologists with long field experience in Seychelles and the Western Indian Ocean.
Gilberte Gendron
Marine Biologist and Environmental Consultant
MSc Oceanography, Université du Québec à Rimouski
Gilberte has 20 years’ experience in biodiversity conservation in Seychelles, starting in 2006 with the Conservation Unit and later serving as Principal Coordinator at the Seychelles National Parks Authority. She has led ecological baseline surveys, coral reef monitoring programmes and management plans for marine protected areas, and has served on the technical working group of the Seychelles Marine Spatial Plan since 2014. She is a core member of the Island Biodiversity and Conservation Centre (University of Seychelles) and co-author of more than a dozen scientific publications.

Léo Barret
Marine Biologist and Environmental Consultant
MSc Oceanography, Université du Québec à Rimouski
Léo has more than 10 years’ experience in oceanography, coral reef and seagrass ecology, and marine spatial planning in Canada and the Western Indian Ocean. He co-authored Status and Trend of Seychelles Coral Reefs: 2026, led the design of the OCEAN’S RESOLVE programme for the Global Fund for Coral Reefs, and developed national seagrass monitoring and restoration protocols. He specialises in GIS-based ecological assessment, coral reef restoration and photogrammetry-based monitoring. PADI Rescue Diver (700+ dives).

A three-tier national framework: citizen-science baselines, annual sentinel-site monitoring, and remote-sensing extent mapping, aligned with SeagrassNet, Seagrass-Watch and MarineGEO.
Seychelles Seagrass Citizen Science Monitoring Protocol for Schools and Community
Barret, L. & Gendron, G. (2026). RECOS project.
Sponsored by the Agence française de développement (AFD).
