Korkkipuu, or cork oak (*Quercus suber*), is a species of oak native to the Mediterranean region, particularly in countries such as Portugal, Spain, Algeria, Morocco, and Tunisia. It is renowned for its thick, spongy bark, known as cork, which is harvested sustainably without harming the tree. The cork oak thrives in warm, dry climates and is often found growing on rocky, nutrient-poor soils.

The bark of the cork oak is unique among trees due to its ability to regenerate after harvesting. Every 9 to 12 years, skilled workers strip the outer layers of bark, leaving the inner layers intact, which allows the tree to produce new cork. This process ensures that the tree remains healthy and can continue producing cork for decades. The sustainability of cork harvesting makes it an environmentally friendly alternative to materials like plastic or synthetic foams.

Cork is widely used in various industries, most notably for wine stoppers, but also in flooring, insulation, and even fashion accessories. Its natural buoyancy, resistance to water, and insulating properties make it valuable in construction and packaging. Additionally, cork forests play a crucial role in combating desertification, improving soil quality, and providing habitat for diverse wildlife.

The economic importance of cork is particularly significant in Portugal, where it contributes to the country’s forestry sector. The country is the world’s largest producer of cork, accounting for roughly half of global production. Beyond its commercial value, the cork oak holds cultural and ecological importance, symbolizing the balance between human use and environmental preservation.
