Today we're going to talk about the famous mountains that form a natural barrier between France and Spain: the Pyrenees. This mountain range separates the Iberian Peninsula from the rest of Europe. It's one of the most recognizable mountain ranges in Europe and one of the most prominent in the world. It's known as the Pyrénées in French, Pirineus in Catalan, and Pirinioak or Auñamendiak in Basque.
In this article we are going to tell you all the characteristics, origin, flora and fauna of the Pyrenees.
Key features
Located in southwestern Europe, the Pyrenees Mountains encompass the small country of Andorra. Their name derives from Pirene, a princess in Greek mythology who was loved by Hercules. Over time, these mountains have gained increasing relevance and importance in the culture of the surrounding communities, not only in their stories but also in their daily activities. Transhumance, the practice of moving livestock from farms to higher mountain pastures during the summer months, is a common custom in the Pyrenees.
Today we know that both sides of the Pyrenees are popular destinations for both recreational activities and mountaineering. This protected natural area boasts a great diversity of flora and fauna. In France lies the Pyrenees National Park, which has a stricter environmental protection regime. The aim is to conserve the richness of the ecosystem in its most natural state. You can explore more about biodiversity in the section on Spain's most important mountains.
Throughout the entire mountain range, there are more than 50 peaks exceeding 3.000 meters in altitude. The mountain chain has a total length of approximately 491 kilometers between France, Spain, and Andorra. It comprises two parallel ranges running east to west from the northern Mediterranean Sea to the Bay of Biscay. The entire mountain system can be described as practically a straight line. Physiographically, it is divided into three sections: eastern, central, and western . Most of the highest peaks are typically found in the central section.
The largest peak is the Aneto with a height of 3.404 meters. It is followed by Posets peak, with 3,375 meters of altitude, and Monte Perdido, whose altitude is 3,355 meters. Unlike other mountain ranges in the world that have similar bills, the development of glaciers is somewhat weaker. There are some in the western and central zone but none in the eastern part. Although it is not stable, the snow level can vary according to the areas. It can normally reach 2.700 meters above sea level.
These mountains don't have large sides and aren't drained by very long rivers. What does make the Pyrenees stand out is their numerous caves and underground rivers. To learn more about the climate that influences these mountains, you can read about the effects of climate change in the region.
Formation and climate of the Pyrenees
In the central Pyrenees, the climate is dry and cold. However, in the eastern areas, summers tend to be considerably warm. The western section is more affected by humid air currents from the Atlantic Ocean . Over the years, erosion from various geological agents and the absence of large or significant glaciers have given the mountains a seemingly worn surface. However, they have maintained their size for thousands of years. Canyons, rocky slopes, and karst plains create truly unique landscapes.
In some areas of the highest parts it has been possible to see old signs of possible glaciations that have left in evidence when seeing the formation of cirques and valleys in the form of U. We remember that the valleys in the form of V are typical of rivers and those that They have a U-shape and are the fruit of glaciers. There are some sources of thermal water that are rich in minerals.
Regarding its formation, some sediments from the Pyrenees have been found dating back to the Paleozoic and Mesozoic eras. However, its geological evolution dates back to the Precambrian . Its formation is due to the collision of the Iberian microcontinent and the southern part of the Eurasian Plate. Both began to move and approach each other until they collided. As a result of the collision, the crust was uplifted and the mountain range was formed. This occurred approximately 100-150 million years ago.
The central Pyrenees region is composed mainly of slate and granite , rocks that are approximately 200 million years old. It also contains limestone, sandstone, dolomite, and other types of sedimentary rocks. To learn more about the geology, we recommend reading about species threatened by climate change.
Flora and fauna of the Pyrenees
As mentioned earlier, the Pyrenees boast a rich biodiversity that conservation efforts aim to preserve. Around 3.500 plant species coexist there, 200 of which are endemic. It's important to note that endemic species are unique to their ecosystems and therefore have greater conservation value. Given the greater rainfall in the western Pyrenees, influenced by the Atlantic, the vegetation is more lush. Conversely, the eastern Pyrenees cannot support such a high number of species.
The flora of the Pyrenees consists of forests and alpine meadows, featuring species such as the holm oak, downy oak, stone pine, and juniper. Some trees exhibit characteristics influenced by the altitude at which they grow, due to climatic conditions that can be studied in trees at different altitudes . Among the unique endemic species of these ecosystems are plants of the genus Xatardia.
As for the fauna, it is mainly represented by the Iberian desman. There are also some bears, the Iberian lynx, the bearded vulture, the Pyrenean newt, the Erebia rondoui butterfly , and the Helicella nubigena mollusk . The disappearance of habitats and some species is due to climate change, a phenomenon you can read more about in the article on glacial remnants in Spain.

There are some iron mines and coal and lignite deposits, which are relatively scarce mineral resources compared to other places. The local economy is based primarily on timber and pasture. Some streams are used to create hydroelectric power plants. Talc and zinc are mined here. The surrounding populations are mainly engaged in agriculture and livestock farming.
I hope that with this information you can learn more about the Pyrenees and its characteristics.
