In the light of research and projects that have marked a rich professional career, a journey deployed in the world of conservation and the development of exceptional places, the author summarizes the key elements that have made it possible to create bridges of meaning between the four following areas : ecology, interpretation, museology and heritage. The main theme of the statements supported demonstrates the extent to which these links of meaning have rested, in particular on the development of educational components inherent to the experience proposed and lived either on the side of the one who defines it or the one who lives it. The unavoidable link that constitutes the rooting of identity, a rooted in territory now in search of new knowledge, anchors, experiences, and developments remains the basis of all actions.
