A dehesa (Spanish pronunciation: [de'esa] ) 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 source of jamón ibérico, the Iberian pig. The main tree component is oaks, usually holm ( Quercus rotundifolia ) and cork ( Quercus suber ). Other oaks, including melojo ( Quercus pyrenaica ) and quejigo ( Quercus faginea ), may be used to form dehesa, the species utilized 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 ]
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 (Quercusrotundifolia), 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 autumn 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 seedlings. 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 ]
The dehesa is in many ways similar to the California oak woodland, although the former is typically much more intensively managed. [5]
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. [6] 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 ]
The area of dehesa usually coincides with areas that could be termed "marginal" because of both their limited agricultural potential (due to the poor quality of the soil) and a lack of local industry, which results in isolated agro-industries and very low capitalization.[ citation needed ]
Dehesa covers nearly 20,000 square kilometers on the Iberian Peninsula, mainly in:
An oak is a hardwood tree or shrub in the genus Quercus of the beech family. They have spirally arranged leaves, often with lobed edges, and a nut called an acorn, borne in a cup. The genus is widely distributed in the Northern Hemisphere; it includes some 500 species, both deciduous and evergreen. Fossil oaks date back to the Middle Eocene. Molecular phylogeny shows that the genus is divided into Old World and New World clades, but many oak species hybridise freely, making the genus's history difficult to resolve.
Quercus ilex, the evergreen oak, holly oak or holm oak is a large evergreen oak native to the Mediterranean region. It is a member of the Ilex section of the genus, with acorns that mature in a single summer.
Quercus suber, commonly called the cork oak, is a medium-sized, evergreen oak tree in the section Quercus sect. Cerris. It is the primary source of cork for wine bottle stoppers and other uses, such as cork flooring and as the cores of cricket balls. It is native to southwest Europe and northwest Africa. In the Mediterranean basin the tree is an ancient species with fossil remnants dating back to the Tertiary period.
Extensive farming or extensive agriculture is an agricultural production system that uses small inputs of labour, fertilizers, and capital, relative to the land area being farmed.
An oak savanna is a type of savanna—or lightly forested grassland—where oaks are the dominant trees. The terms "oakery" or "woodlands" are also used commonly, though the former is more prevalent when referencing the Mediterranean area. These savannas were maintained historically through wildfires set by lightning, humans, grazing, low precipitation, and/or poor soil.
Jamón is a kind of dry-cured ham produced in Spain. It is one of the most globally recognized food items of Spanish cuisine. It is also regularly a component of tapas.
Quercus coccifera, the kermes oak, is an oak bush in the Ilex section of the genus. It has many synonyms, including Quercus calliprinos. It is native to the Mediterranean region and Northern African Maghreb, south to north from Morocco to France and west to east from Portugal to Cyprus and Turkey, crossing Spain, Italy, Libya, Balkans, and Greece, including Crete. The Kermes Oak was historically important as the food plant of Kermes scale insects, from which a red dye called crimson was obtained. The etymology of the specific name coccifera is related to the production of red cochineal (crimson) dye and derived from Latin coccum which was from Greek κόκκος, the kermes insect. The Latin -fera means 'bearer'.
Jamón ibérico, "Iberian ham," is a variety of jamón or presunto, a type of cured leg of pork produced in Spain and Portugal.
Quercus faginea, the Portuguese oak, is a species of oak native to the western Mediterranean region in the Iberian Peninsula. Similar trees in the Atlas Mountains of northwest Africa are usually included in this species, or sometimes treated as a distinct species, Quercus tlemcenensis. It occurs in mountains from sea level to 1,900 metres above sea level, and flourishes in a variety of soils and climates. Out of all the oak forests in the Iberian Peninsula, the southern populations of Portuguese oak were found to have the highest diversity and endemism of spider species.
The woodlands of the Iberian Peninsula are distinct ecosystems on the Iberian Peninsula. Although the various regions are each characterized by distinct vegetation, the borders between these regions are not clearly defined, and there are some similarities across the peninsula.
Saucedilla is a municipality located in the province of Cáceres, Extremadura, Spain. It belongs to the Campo Arañuelo County, the capital of which is Navalmoral de la Mata.
The Iberian pig is a traditional breed of the domestic pig that is native to the Iberian Peninsula. The Iberian pig, whose origins can probably be traced back to the Neolithic, when animal domestication started, is currently found in herds clustered in Spain and the central and southern part of Portugal.
Sierra Suroeste is a comarca located in southwestern province of Badajoz in the autonomous community of Extremadura, western Spain. Its capital and largest city is Jerez de los Caballeros.
Quercus rotundifolia, the holm oak or ballota oak, is an evergreen oak native to the western Mediterranean region, with the majority on the Iberian Peninsula and minor populations in Northwest Africa. The species was first described by Jean-Baptiste Lamarck in 1785. It is the typical species of the Iberian dehesa or montado, where its sweet-astringent acorns are a source of food for livestock, particularly the Iberian pig. Its acorns have been used for human nourishment since the Neolithic era. It is placed in section Ilex. Some authors described it as a subspecies of Quercus ilex.
