A pioneer in canopy exploration

He is particularly known for having conceived the "Raft of the Canopies," an innovative device for exploring the canopy, used in numerous scientific expeditions around the world.

Having lived in Montpellier for several decades, he taught botany there for nearly thirty years. His commitment continued after his academic career, through lectures, books and documentary films, including Il était une forêt , released in 2012.
