Silver birch

This tree can grow up to 25 m tall and is recognisable due to its white bark, warty twigs and weeping aspect (drooping twigs). In the Champsaur, birch sap is extracted using the Canadian method to make a drink rich in sugars and trace elements. Used by mankind for centuries, especially in Nordic countries, it was once considered a miraculous tree thanks to its host of medicinal and food uses.
