Invasive exotic plants in a natural environment in Haute-Garonne.

The Departmental Federation of Hunters of Haute-Garonne (FDC31) is coordinating the SAGE3 project, a three-year initiative aimed at structuring the fight against invasive exotic species across the region.

The program, supported by the EPTB Garonne, addresses a major ecological challenge for the preservation of Natura 2000 sites. These non-native species threaten the balance of natural habitats by competing directly with local flora and fauna.
Since 2025, the initiative has mobilized a wide network of stakeholders, including local authorities, industrial partners, and environmental associations. This collaborative effort has led to the creation of a dispersion model for invasive plants, helping to identify priority intervention zones.
For 2026, the project focuses on studying three experimental sites. These efforts will enable the development of tailored management plans, ranging from prevention in less affected areas to containment actions in heavily colonized sectors.
