Biodiversity and traditional knowledge in Reunion Island: case of "competition zerbaz péi".
In the Reunion Island, the annual education project-"zerbaz péi " organised by the Association pour la promotion des Plantes Médicinales D'Outre Mer (APLAMEDOM), a member of the cultural heritage of The Reunion Island, aims at making an inventory of the family practices on aromatic and medicinal plants. "Zerbaz péi" refers to the use of healing plants, called collectively "zerbaz" or herbal teas. The use of plants to the Reunion Island enables us to understand the history of the colonization of the island. Plants in the island can be categorised into 2 categories: those already present on the island, including the endemics and the natives; and those brought from outside, the exotics. The objective of the competition was to catalogu and build an inventory of the popular knowledge through the organization of a competition of herbariums among students in the primary and high schools throughout the entire island.
