The Portuguese oak is a marcescent tree, meaning that its leaves dry out in autumn but remain on the tree throughout the winter, only falling when new foliage emerges in spring. It can reach around 20 metres in height and develops a broad, dense crown, providing shade and shelter for numerous species.

Native to the Iberian Peninsula and characteristic of Mediterranean-climate regions, it is well adapted to a wide range of soils and environmental conditions. It occurs naturally in woodlands and shrublands, both as a solitary tree and as part of mixed oak forests.

The flowers appear in spring and produce acorns that ripen in autumn. These provide an important food source for wildlife, including birds and mammals, contributing to the balance and functioning of Mediterranean ecosystems.

It’s hard and durable wood was widely used throughout history in construction and a variety of carpentry applications. Today, the Portuguese oak is valued primarily for its ecological importance and its contribution to the landscape.

Portuguese oak woodlands are among the most biodiverse habitats of the Mediterranean region, providing refuge for numerous species of plants, birds, insects, and mammals, including some of the most emblematic members of Iberian wildlife.
