Foret Primaire On the initiative of the botanist Francis Hallé, our association is working to create a vast area of European dimension and large surface area - about 70,000 hectares - in which an intact forest will evolve autonomously, renewing and developing its fauna and flora without any human intervention, and this over a period of several centuries. This area, which has yet to be located, will be cross-border, with a French base. Crédit Photos : Opération Canopée © Francis Hallé Des arbres dans la forêt primaire de Bialowieza (Pologne). (AFP)
