Observing Nature to Manage It Better: Naturalistic Inventory and Biodiversity in the Forest of Fontainebleau

The Foundation of Ecological Management : Naturalistic Inventory

Effective management of natural areas, habitats and species depends on our ability to understand the ecological characteristics of these environments. This process begins with a naturalistic inventory – a methodical approach to observe, identify, and record species and habitats.

Far from being a simple list of flora and fauna, a naturalistic inventory provides essential data for:

• Mapping ecological continuities and biodiversity hotspots,

• Monitoring the evolution of species and habitats over time,

• Designing conservation and restoration strategies tailored to local conditions.

In this context, students were trained in field techniques and observation methods used by ecologists and biodiversity specialists.

A Living Laboratory: Learning in the Forest of Fontainebleau

The field session offered an immersive learning experience in a unique ecological setting. The Fontainebleau Forest, with its mosaic of habitats – heathlands, woodlands, wetlands – provided an ideal context for exploring the complexity of natural ecosystems.

Students practiced:

• Species identification using morphological traits and field guides,

• Habitat characterization through analysis of vegetation structure and soil conditions,

• Use of bioindicators to infer environmental conditions.

One example discussed on-site was the presence of Pteridium aquilinum (commonly known as bracken or eagle fern), a plant species known to indicate acidic and nutrient-poor soils. Such indicators are invaluable in evaluating habitat quality and informing land management decisions.

Linking Observation to Action

Beyond the scientific knowledge, the session also encouraged students to reflect on the role of biodiversity in territorial resilience, and on the importance of integrating ecological diagnostics into land-use planning and environmental policies.

By confronting the realities of fieldwork, the ENVIM students strengthened their ability to:

• Conduct ecological assessments in various contexts,

• Contribute to biodiversity action plans,

• Translate ecological data into operational and strategic recommendations for public and private actors.

This hands-on approach to ecological expertise is at the heart of ISIGE’s pedagogy, combining scientific rigor with a strong engagement in the service of sustainable transitions.
