The ideal natural environment for the Iberian pig is the pasture (dehesa), the manifestation of the Mediterranean forest which provides the animal with everything it needs to be a happy pig grazing on the green. The distinctive trees of the dehesa are mainly holm oaks, cork trees and gall oak.
More than half of the global holm oak grove land is located in Spain. There are more than one and a half million hectares distributed among Extremadura, Andalusia, Castilla La Mancha and Castilla León. Half of the Spanish holm oak grove area is located in Extremadura.
The Iberian pig is a privileged animal that does not suffer from the overcrowding experimented by other animals raised in industrial areas for human consumption. In order to ensure a balanced diet and the exercise needed for the fat to infiltrate the meat, each pig has 2 hectares of land. In this environment of great ecological value the pig feeds on natural grazing land, small insects and the delicacy that grows during the season of montanera: the acorn.
