To share an environmental culture with you and experience moments of emotion and knowledge, the CPIE offers a program of conferences, days and guided tours in an exceptional territory which brings together the Amance arboretum, the forest and the pond of Brin and the INRAE forestry research center. Activities are organized and allow you to understand the environment with different approaches: naturalist, historical, geographical, etc. They are open to all and all those wishing to better understand their local environment. The Amance arboretum, more than a hundred years old, is an unusual and unique heritage in the entire eastern quarter of France. It has nearly 350 different species of trees from all continents. Activities are organized regularly. The public is welcomed at the INRAE reception, located opposite the arboretum.
