The Pre-Pyrenees is an extremely diverse territory where, thanks to the differences in climate between the areas, it is possible to find clearly differentiated ecosystems. As a result of this diversity, it is possible to observe a large number of botanical species.
Among the most characteristic habitats, you’ll find oak forests or holm oak forests, kermes oak forests, Portuguese oak forests, as well as various pine, silver fir and beech forests; the latter are located on the Atlantic side of the different Pre-Pyrenean mountain ranges. In the landscape, two species of bushes—common box and Echinospartum horridum—can be found, always in the driest areas. The limestone and conglomerate crags are home to the other species, forming part of the spectacular geological formations of the Pre-Pyrenees.
