Cork Oak Tree

Quercus suber

Description:

The tree forms a thick, rugged bark containing high levels of suberin. 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, in fact, no trees are cut down during the harvesting process. Only the bark is extracted, and a new layer of cork regrows, making it a renewable resource. The tree is cultivated in Spain, Portugal, Algeria, Morocco, France, Italy and Tunisia. Cork Oaks are considered to be soil builders and their fruits have been shown to have useful insecticidal properties. Wikipedia

Habitat:

UC Berkeley Botanical Gardens, Berkeley, CA.
