I don't think there is a special term in English

Cork is the outer bark of the cork oak tree. Scientifically the Latin name for the cork oak tree is Quercus (oak) suber (cork). This remarkable tree has a bark (suberose parenchyma) which is unique throughout the plant kingdom. The cork bark can be 'stripped' off allowing new bark to grow in its place without killing or damaging the trees. This makes every tree a renewable source of raw material. The cork is harvested (peeled) from each tree time after time. The first stripping of the cork bark occurs approximately 20 years after a sapling is planted. After each stripping the cork tree fully regenerates its precious bark and is harvested over and over again every 9 to 10 years until the tree is approximately 200 years old. At that time the aged tree is removed and two new saplings are planted in its place, ensuring the cork forest continues to flourish and expand. Additionally the cork oak tree also reproduces off-springs naturally by dropping acorns that seed themselves and eventually mature into productive full grown trees.

Today's methods of cultivation originated in southern Spain and Portugal, probably in the 15th century. The practice of growing trees to produce harvestable cork is very lengthy and specialised, which is the foundation of a very valuable and unique ecosystem. The first cork stripping, which is commercially useless, happens when the trees are 25 years old, and only subsequent strippings, years later, result in uniform, commercially useful cork. Quercus suber is generally managed in pastures rather than harvesting bark from wild trees, to control for age and health of the trees.
