Devesa da Rogueira Nature · Folgoso do Courel, Quiroga, Lugo Native woodland on the northern slope of the Formigueiros peak where more than eight hundred species of trees and plants live side by side — ash, beech, yew and birch on the same hillside — thanks to the contact between limestone and siliceous soils. It was the first woodland in Spain to obtain FSC certification and is included in the Ancares-Courel special area of conservation. The two versions disagree over its extent: some three hundred hectares according to one, some three thousand according to the other.
