Cork is the outer bark of the
evergreen cork oak (Quercus suber). This variety of oak
grows mainly in Portugal, Spain, southern France, Italy,
and the North Africa.
Cork is sustainable. It is
harvested by stripping the bark every nine years. Each
cork oak tree provides an average 16 harvests over its
150-200 year lifespan.
Cork harvesting is
one of the best examples of a sustainable agro-forestry
system, where people use the natural resources around
them without disturbing or destroying nature. Cork
harvesting has been a way of life in the Mediterranean
for at least a thousand years. The forests are ancient.
