A dehesa in Bollullos Par del Condado, Huelva, southern Spain

A dehesa is a multifunctional, agrosylvopastoral system (a type of agroforestry) and cultural landscape of southern and central Spain and southern Portugal; in Portugal, it is known as a montado. Its name comes from the Latin 'defensa', (fenced), referring to land that was fenced, and usually destined for pasture.[1] Dehesas may be private or communal property (usually belonging to the municipality). Used primarily for grazing, they produce a variety of products, including non-timber forest products such as wild game, mushrooms, honey, cork, and firewood. They are also used to raise the Spanish fighting bull and the Iberian pig. The main tree component is oaks, usually holm (Quercus ilex) and cork (Quercus suber). Other oaks, including melojo (Quercus pyrenaica) and quejigo (Quercus faginea), may be used to form dehesa, the species depending on geographical location and elevation. Dehesa is an anthropogenic system that provides not only a variety of foods, but also wildlife habitat for endangered species such as the Spanish imperial eagle.[2]

By extension, the term can also be used for this style of rangeland management on estates.[citation needed]



Dehesa in Extremadura, Spain

The dehesa is derived from the Mediterranean forest ecosystem, consisting of grassland featuring herbaceous species, used for grazing cattle, goats, and sheep, and tree species belonging to the genus Quercus (oak), such as the holm oak (Quercus ilex sp. ballota), although other tree species such as beech and pine trees may also be present. Oaks are protected and pruned to produce acorns, which the famous black Iberian pigs feed on in the fall during the montanera.[3] Ham produced from Iberian pigs fattened with acorns and air-dried at high elevations is known as Jamón ibérico ("presunto ibérico", or "pata negra" in Portuguese), and sells for premium prices, especially if only acorns have been used for fattening.

In a typical dehesa, oaks are managed to persist for about 250 years. If cork oaks are present, the cork is harvested about every 9 to 12 years, depending on the productivity of the site. The understory is usually cleared every 7 to 10 years to prevent the takeover of the woodland by shrubs of the rock rose family (Cistaceae), often referred to as "jara", or by oak sprouts. Oaks are spaced to maximize overall productivity by balancing light for the grasses in the understory, water use in the soils, and acorn production for pigs and game.[4]

There is debate about the origins and maintenance of the dehesa, and whether or not the oaks can reproduce adequately under the grazing densities now prevailing.[citation needed]

Importance and economic contextEdit

The dehesa system has great economic and social importance on the Iberian Peninsula because of both the large amount of land involved and its importance in maintaining rural population levels. The major source of income for dehesa owners is usually cork, a sustainable product that supports this ancient production system and old growth oaks.[5] High end black iberian pigs and sale of hunting rights also represent significant income sources. Periodic hunts in the dehesa are known as the monteria. Groups attend a hunt at a private estate and wait at hunting spots for game to be driven to them with dogs. They usually pay well for the privilege, hunting wild boar, red deer and other species.[citation needed]



Dehesa covers nearly 20,000 square kilometers on the Iberian Peninsula, mainly in:
