The island of Porquerolles, located in the Var department in the Provence-Alpes Côte d'Azur region, possesses exceptional natural heritage. In fact, the varietal collections of fruit trees found there are classified as collections of national interest. There are a wide variety of fig trees, mulberry trees and even olive trees. These trees have borne witness to the history of the Mediterranean, the migrations of humanity and their agricultural activities over thousands of years. If this heritage and the biodiversity of Porquerolles are to be conserved, it is necessary to ensure the preservation and renewal of these collections.
