Public Description:

Quercus petraea, known as “sessile oak”, is native to most of Europe, Anatolia and Iran. It is a deciduous tree which can reach over 30 m high and 3 m in diameter and can live up to 300 years old.

The Sessile oak is one of the most important plant species, both economically and ecologically. Oak timber is traditionally used for building, ships and furniture. Today, the best woods are used for quality cabinets, coatings and barrel manufacturing. In the fall, acorns are an important source of food for some animals.
