Forests of the Iberian Peninsula

The woodlands of the Iberian Peninsula are special ecosystems found across a large land area. This land, called the Iberian Peninsula, includes countries such as Spain, Portugal, as well as smaller areas like Andorra, Gibraltar, and the southern part of France. These forests are home to many different plants and animals, each region having its own unique look and life.

These woodlands help the environment in many ways. They help control the climate, provide clean water, and give animals and plants a place to live. People have lived near these forests for thousands of years, using the wood for building and other needs. Today, protecting these forests is very important to keep nature balanced and help wildlife.

Origin and characteristics

The Mediterranean Sea changed a lot in the past. The continental plates of Europe and Africa moved, changing the climate and the plants that could grow there.

The Iberian Peninsula is in southwestern Europe near North Africa. Because of this special place, it has many kinds of plants from both areas. These include plants that like heat, plants that grow in dry places, and plants from cooler mountains. The diverse mountains, such as the Cordillera Bética, Sistema Ibérico, and Pyrenees, created many different places where plants could grow and thrive. This made the area very rich in different kinds of plants.

The Eurosiberian region

The Eurosiberian Atlantic zone runs through northern Portugal, the Galician Massif, Cantabrian Mountains, and the western and central Pyrenees. It has a humid climate with mild winters. This area includes parts of Asturias, Cantabria, the Basque Country, and northwest Navarre.

The main plants here are deciduous oak forests, with trees like European ash and hazels. Higher up, you’ll find beeches and sometimes silver firs. People have changed much of this land into meadows, but some original plants still survive at the edges. Important forests in this area include beech, oak, birch, and fir forests.

The Mediterranean region

The Mediterranean region covers most of the Iberian Peninsula, including the Balearic Islands. This area has long, dry summers and different amounts of rain, from very wet to quite dry. Temperatures can change a lot, from very warm to very cold, with some places never freezing and others getting below -20 °C in winter.

Typical forests in this region include evergreen trees like oak, cork oak, wild olives, and juniper. In warmer or sandy areas, you might find Aleppo pine forests or juniper and stone pine forests. Some very dry places, like parts of Murcia and Almeria, have only European fan palms, thorny thickets, or Kermes oak groves. Similar plants grow in salty or dry inland areas like the Ebro river valley.

Shrubby borders or undergrowths

Shrubby borders are important parts of forests. They help forests grow and give food and shelter to animals. These borders are made of spiny shrubs like gorse, box, and thyme, depending on the forest and the climate.

Stages of degradation

The forests of the Iberian Peninsula change when they are damaged. A healthy forest has many trees and local plants. Next, there are fewer native trees and more plants like holly and maple.

After that, native trees disappear, and pine forests grow. These forests have dry-loving bushes.

If damage keeps happening, trees disappear completely. Thorny bushes and small plants grow instead. Finally, even these plants vanish. Only thin grass and bare soil remain, creating a dry, desert-like area.
