The Cork Oak (Quercus suber) is a medium-sized, evergreen oak tree that is native to southwest Europe and northwest Africa. The tree forms a thick, rugged and corky bark containing high levels of suberin (a waxy substance that is a main constituent of cork). Over time, the cork cambium layer of bark can develop considerable thickness and can be harvested every 9 to 12 years to produce cork. The harvesting of cork does not harm the tree and a new layer of cork regrows, making it a renewable resource.
