The island of Porquerolles, located in the Var department in the Provence-Alpes Côte d'Azur region, has an exceptional natural heritage. In fact, the varietal collections of fruit trees found there are classified as collections of national interest. There are collections of fig, mulberry and olive trees. These trees bear witness to the history of the Mediterranean, the migrations of men and their agricultural activities for thousands of years. It is necessary to ensure the preservation and renewal of these collections in order to conserve this heritage and maintain the biodiversity of Porquerolles.
