This photo was taken on the island of Majorca, Balearic Islands. Olive trees are very hardy, drought-, disease- and fire-resistant, and can live for a very long time. Its root system is very robust and capable of regenerating the tree even if the above-ground structure is destroyed. The older an olive tree is, the broader and gnarlier its trunk appears. Many olive trees in the groves around the Mediterranean are said to be several centuries old, and in some cases this has been verified scientifically.
