40 Years of IFN: Monitoring the Evolution of French Forest Resources

Established 40 years ago, the Institut Français de l'Observation Forestière (IFN) provides vital information on the evolution of forest resources in France. Since 1992, IFN has collected extensive ecological data regarding forest biomass and health. It categorizes trees into three diameter classes: small (10 cm), medium (25 cm), and large (50 cm). This comprehensive data collection informs sustainable forest management, conservation efforts, and policy-making, ensuring that the French forest ecosystem is preserved for future generations.
