This site documents a personal and professional approach at the intersection of urban ecology, naturalist data, geomatics and decision support.
Observe → Understand → Map → Share → Act
A senior engineer of the French Corps des Mines (Ingénieur général des Mines), field naturalist and geomatician, I produce and publish data on the biodiversity of urban and peri-urban environments in the Pays de la Loire region. These data feed into institutional policies, NGO programmes and contributions to public debate. This site is their public documentation.
This site brings together work belonging to four distinct registers — 🏛️ institutional 🤝 associative 💬 public debate 🔭 naturalist — whose interplay informs the reading of each section.
Read according to your profile
Academic assessor / jury
Background, degrees, recommendation letters, peer-reviewed scientific output.
DDRS auditor / institutional
Campus biodiversity policy, indicators, CGE label, partnership agreements.
Public partner / elected official
Development files, documented contribution to public debate, sourced cartographic data.
Naturalist / NGO
Field observations, protocols, regional atlases, participatory science.
Curious about data, AI, maps
Technical architecture, QGIS piloting in natural language, iNaturalist → GBIF → SINP data flows.
The site's main areas
Personal background & positioning
An atypical trajectory between the Corps des Mines, digital engineering and scientific ecology. Degrees, evidence, registers of action.
IMT Atlantique — TES training & campus biodiversity
Six years of biodiversity policy across three campuses. more than 430 taxa as of 11 September 2026, 8 agreements, DDRS file.
Naturalist observations and iNaturalist
More than 8,600 records published as of 11 September 2026. From the field to the SINP, via iNaturalist and GBIF.
Pays de la Loire — data, connectivity, species
Contribution to the regional bumblebee atlas, green and blue infrastructure, wetlands, biodiversity hotspots.
Champ de Manœuvre — sensitive site, documented file
Analysis of the avoid-reduce-offset (ERC) sequence, protected amphibians, heritage trees, HD LiDAR elevation.
Key results
Key results — biodiversity on the IMT Atlantique campuses
- 6 academic years of structured biodiversity work (2020-2021 → 2025-2026)
- 3 campuses covered: Brest, Nantes, Rennes (38.75 hectares in total)
- 28% of the cadastral parcels of the three campuses under differentiated management (May 2026 survey, corrected in September): 109,526 m² out of 387,645 m²
- More than 430 taxa, including 370 species, observed on the three campuses (IMT Atlantique iNaturalist project) as of 11 September 2026
- 8 agreements signed with LPO, Bretagne Vivante, GRETIA, Nantes Métropole, ONIRIS, Fédération des Amis de l'Erdre
- Associated SDGs: SDG 4 · SDG 13 · SDG 14 · SDG 15 · SDG 17
A method common to all projects
Whatever the register — institutional, associative, contribution to public debate or personal practice — the workflow is the same:
Areas of expertise
The work documented on this site spans seven complementary fields of scientific and applied ecology. These fields rely on cross-cutting tools — geomatics and, more recently, agentic AI — to produce, organise and share data and knowledge on biodiversity. Here, AI is a tool in the service of this work, not an end in itself.
Conservation ecology
Assessment of ecological issues, protected species, habitats, ecological connectivity, the avoid-reduce-offset (ERC) sequence, prioritisation of actions.
Urban and territorial ecology
Campuses, development zones (ZAC), peri-urban environments, headwater catchments, green and blue infrastructure, the effects of land development on living systems.
Community ecology and naturalist surveys
Multi-taxon monitoring, observed species, iNaturalist projects: bumblebees, amphibians, reptiles, birds, pollinators.
Participatory science and naturalist data
Production, structuring, publication and reuse of open data; distinguishing opportunistic observation, protocols and collaborative projects.
Ecological geomatics and spatial ecology
Mapping, GIS, connectivity, buffer zones, friction, dashboards — QGIS, Python, R, PostGIS.
Light ecological management and engineering
Differentiated mowing, ponds, hedgerows, campus management, indicators and monitoring of management responses.
Science–public action interface, mediation and training
Turning ecological knowledge into decision-support materials; contribution to public debate; mediation between local authorities, NGOs and government services; training and network facilitation (TES programme, participatory science).
