How are the Eastern, Central, and Western Pyrenees different?

The Pyrenees are divided into three natural regions—the Western, Central, and Eastern Pyrenees—based on their physiography, climate, vegetation, and cultural distinctions.1

Regional Characteristics

• Western Pyrenees: This region is characterized by a strong oceanic influence, which brings milder temperatures and higher rainfall. The landscape features broad-leaved deciduous forests, such as beeches, which grow at higher altitudes than in other parts of the range. An Atlantic group of flora predominates here.23
• Central Pyrenees: This area contains the highest tectonic development and the primary granitic axial zones. It experiences significant thermal contrasts, particularly on the southern slopes, where drier conditions favor drought-resistant mountain pines over deciduous trees.123
• Eastern (Mediterranean) Pyrenees: Influenced by the Mediterranean, this region is shaped by damp air from the sea, though it also includes drier, sunnier areas. The vegetation is dominated by evergreen broad-leaved trees that are well-adapted to drought.23

These divisions are further supported by linguistic, ethnic, and cultural differences among the people inhabiting these distinct zones.1
