Black pigs in dehesa in Estramadura, Spain. A dehesa is an agro-sylvo-pastoral mode of cultivation formed by a sparse undergrowth grazing where pigs or sheep graze freely and where green or cork oaks grow, cut and exploited. This very old system persists in the poor and dry areas of the Mediterranean basin and covers several million hectares in the Iberian Peninsula.
