But in Coruche, a rural area south of the Tagus River known as Portugal’s “cork capital,” the bang of trees falling to the ground doesn’t follow the sound of the ax strokes.In Portugal, the world’s largest cork producer, the oaks are so cherished they were chosen as the country’s national tree and are protected by law, so it’s forbidden to cut them.
After six months of aging to remove moisture, they will be sorted according to their thickness and quality, then boiled to clean impurities and make the material softer and easier to handle.
The cork oak’s thick bark adapted to defend the tree from fire, making it a powerful insulating material that’s been used to shield fuel tanks on NASA spacecraft and electric car batteries.
One of the world’s oldest known cork oak trees, planted in 1783 in Águas de Moura, is known as “the whistler” because so many birds visit its large sprawling branches.
Interspersing cork oak trees with animals and crops can boost production and biodiversity, but also build soil, control erosion, retain water, combat desertification and sequester carbon, says Pinto-Correia.
