The &amp;#039;&amp;#039;&amp;#039;Iberian System&amp;#039;&amp;#039;&amp;#039;{{efn|{{langx|es|Sistema Ibérico}} {{IPA|es|sisˈtema jˈβeɾiko|}}; {{langx|an|Sistema Iberico}} {{IPA|an|sisˈtema jβeˈɾiko|}}; {{langx|ca-valencia|Sistema Ibèric}} {{IPA|ca-valencia|sisˈtema jˈbɛɾik|}}}} is one of the major systems of [[mountain range]]s in [[Spain]].&lt;br /&gt;
It consists of a vast and complex area of mostly relatively high and rugged mountain chains and massifs located in the central region of the [[Iberian Peninsula]], but reaching almost the [[Mediterranean coast]] in the [[Valencian Community]] in the east.&lt;br /&gt;
&lt;br /&gt;
The system is [[hydrography|hydrographically]] important, as it separates the watersheds of most of the major rivers in Spain and [[Portugal]], including the [[Ebro]] basin to the east from the basins of the [[Douro]], [[Tagus]], [[Guadiana]] ([[Záncara]]-[[Gigüela]]), [[Júcar]] and [[Turia (river)|Turia]] to the west and south.&lt;br /&gt;
&lt;br /&gt;
There are important [[mining]] areas in some of the ranges such as [[Sierra Menera]], [[Andorra-Sierra de Arcos|Sierra de Arcos]] and [[Sierra de San Just]], making the system one of the chief mining regions in Spain since ancient times.&amp;lt;ref&amp;gt;{{Cite web |url=http://155.210.12.154/acad/epAsignaturas.php?id=5120&amp;amp;p=1 |title=Recursos minerales de España - Universidad de Zaragoza |access-date=2011-06-05 |archive-url=https://web.archive.org/web/20110810142832/http://155.210.12.154/acad/epAsignaturas.php?id=5120&amp;amp;p=1 |archive-date=2011-08-10 |url-status=dead }}&amp;lt;/ref&amp;gt;&amp;lt;ref&amp;gt;Luis Diego Arribas, &amp;#039;&amp;#039;Contemporary Art and Opencast Mining&amp;#039;&amp;#039;, University of Zaragoza, 2009&amp;lt;/ref&amp;gt; One of the [[comarcas of Aragon]] located in the Iberian System was given the name of [[Cuencas Mineras]], [[Literal translation|lit.]] &amp;#039;Mining Basins&amp;#039;, since mining is the main activity in the comarca.&amp;lt;ref&amp;gt;[http://www.comarcaacomarca.com/id/15/comarca.asp?q=Cuencas%20Mineras Comarcas de Aragón - Cuencas Mineras]&amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
== Location and description ==&lt;br /&gt;
The Sistema Ibérico mountain range borders the [[Meseta Central]] on its eastern end and separates the Meseta Central from the [[Ebro]] valley and from the [[Mediterranean]] coast.&lt;br /&gt;
&lt;br /&gt;
This system runs northwest-southeast between the Ebro plain and the Meseta Central for over 500&amp;amp;nbsp;km, from the [[La Bureba]] corridor in [[Burgos Province]] close to the [[Cordillera Cantábrica]] to the [[Mediterranean]] sea close to [[Valencia, Spain|Valencia]] in the south and close to [[Tortosa]] and the [[Ebro Delta]] in the east. The bulk of the Sistema Ibérico is located in the southern half of [[Aragon]]. The [[Prebaetic System]] rises south of the southernmost end of the Iberian System.&lt;br /&gt;
&lt;br /&gt;
The [[geology]] of the Iberian System is complex, for it can hardly be defined as a homogeneous system. It is composed of a haphazard and motley series of [[mountain range]]s, [[massif]]s, [[plateau]]s and [[Depression (geology)|depression]]s without a definite common [[Petrology|petrologic]] composition and overall structure. [[Nummulite]] [[limestone]], [[marble]] and [[sandstone]] are common throughout the area. Some of the parts of the system stand geologically isolated, interrupting the continuity of the whole, linked to the other parts through high plateaus of varying altitudes.&amp;lt;ref&amp;gt;[http://naturaxilocae.blogspot.com/2011/05/geolodia-2011-entre-la-sierra-de.html Natura Xilocae - Entre la sierra de Caldereros y el Maestrazgo de Teruel]&amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
==Ecology and human activity==&lt;br /&gt;
&lt;br /&gt;
===Population decline===&lt;br /&gt;
Large zones of the mountainous Iberian System have undergone heavy [[depopulation]] since the early 20th century. There are many [[ghost town]]s and [[abandoned village]]s scattered across different parts of the Iberian System, especially in [[Teruel Province]].&amp;lt;ref&amp;gt;[http://lospueblosdeshabitados.blogspot.com/search/label/TERUEL%20%20-Collado%20de%20la%20Grulla- Pueblos deshabitados - Collado de la Grulla (Teruel)]&amp;lt;/ref&amp;gt; Currently a great number of surviving towns have only a residual population. In some cases, many of the inhabitants are not natives anymore but immigrants from [[Romania]] or the [[Maghreb]] working as contract laborers in agricultural activities.&amp;lt;ref&amp;gt;[http://www.mibolso.com/reportajes/un_pueblo_de_teruel_salvado_por_la_inmigracion_1.html Un pueblo de Teruel, salvado por la inmigración]&amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The exodus from the rural mountainous areas in Spain rose after [[General Franco]]&amp;#039;s [[Stabilization Plan]] in 1959. The [[population decline]]d steeply as people emigrated towards the industrial areas of the large cities and the coastal towns where the tourism industry was growing. Other causes of high emigration have been the abandonment by the local youth of traditional agricultural practices that were the mainstay of the village economy, such as [[sheep]] and [[goat]] rearing, as well as the lifestyle changes that swept over rural Spain during the second half of the 20th century.&amp;lt;ref&amp;gt;[http://despoblacion.blogia.com/temas/la-despoblacion-en-aragon.php Despoblación en Aragon] {{webarchive|url=https://web.archive.org/web/20120823033158/http://despoblacion.blogia.com/temas/la-despoblacion-en-aragon.php |date=2012-08-23 }}&amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
===Fauna===&lt;br /&gt;
The heavy depopulation has favored wildlife so that one of the last colonies of [[griffon vulture]]s in Europe is in the Iberian System. [[Iberian wolf|Wolves]] and eagles (&amp;#039;&amp;#039;[[Aquila chrysaetos]]&amp;#039;&amp;#039;, &amp;#039;&amp;#039;[[Hieraaetus fasciatus]]&amp;#039;&amp;#039;, &amp;#039;&amp;#039;[[Hieraaetus pennatus]]&amp;#039;&amp;#039;, &amp;#039;&amp;#039;[[Circaetus gallicus]]&amp;#039;&amp;#039;) are also relatively common in the lonely heights. Among the mammals, the [[Spanish ibex]], [[roe deer]], [[wild boar]], [[European badger]]s, [[common genet]]s, among others, have their habitat in many of these desolate mountain ranges.&amp;lt;ref&amp;gt;[https://www.questia.com/read/1G1-131432781 Walking In Spain]&amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The most common [[reptile]]s in the Iberian System are &amp;#039;&amp;#039;[[Lacerta lepida]]&amp;#039;&amp;#039;, &amp;#039;&amp;#039;[[Psammodromus algirus]]&amp;#039;&amp;#039;, &amp;#039;&amp;#039;[[Psammodromus hispanicus]]&amp;#039;&amp;#039;, &amp;#039;&amp;#039;[[Podarcis muralis]]&amp;#039;&amp;#039; and &amp;#039;&amp;#039;[[Podarcis hispanicus]]&amp;#039;&amp;#039;. &amp;#039;&amp;#039;[[Chalcides chalcides]]&amp;#039;&amp;#039;, &amp;#039;&amp;#039;[[Chalcides bedriagai]]&amp;#039;&amp;#039; and &amp;#039;&amp;#039;[[Anguis fragilis]]&amp;#039;&amp;#039;, are relatively rarer. The snakes present in these mountains are &amp;#039;&amp;#039;[[Natrix maura]]&amp;#039;&amp;#039;, &amp;#039;&amp;#039;[[Natrix natrix]]&amp;#039;&amp;#039;, &amp;#039;&amp;#039;[[Malpolon monspessulanus]]&amp;#039;&amp;#039;, &amp;#039;&amp;#039;[[Elaphe scalaris]]&amp;#039;&amp;#039;, &amp;#039;&amp;#039;[[Coronella girondica]]&amp;#039;&amp;#039;, &amp;#039;&amp;#039;[[Coronella austriaca]]&amp;#039;&amp;#039; and &amp;#039;&amp;#039;[[Vipera latastei]]&amp;#039;&amp;#039;.&lt;br /&gt;
&lt;br /&gt;
Some [[amphibian]]s are abundant in or near ponds and rivulets throughout the whole system, such as &amp;#039;&amp;#039;[[Rana perezi]]&amp;#039;&amp;#039;, &amp;#039;&amp;#039;[[Bufo bufo]]&amp;#039;&amp;#039;, &amp;#039;&amp;#039;[[Bufo calamita]]&amp;#039;&amp;#039;, &amp;#039;&amp;#039;[[Alytes obstetricans]]&amp;#039;&amp;#039;, &amp;#039;&amp;#039;[[Triturus marmoratus]]&amp;#039;&amp;#039; and &amp;#039;&amp;#039;[[Lissotriton helveticus]]&amp;#039;&amp;#039;, the latter also at high altitude, whether in intermittent or permanent bodies of water. &amp;#039;&amp;#039;[[Hyla arborea]]&amp;#039;&amp;#039; and &amp;#039;&amp;#039;[[Salamandra salamandra]]&amp;#039;&amp;#039; are somewhat rarer, but still having a wide distribution, especially in humid forested zones. The Iberian ribbed newt &amp;#039;&amp;#039;([[Pleurodeles waltl]])&amp;#039;&amp;#039;, however, is rarely found in the mountainous areas. Aquatic invertebrates, including the &amp;#039;&amp;#039;[[Austropotamobius pallipes]]&amp;#039;&amp;#039; crayfish, and certain fishes, such as &amp;#039;&amp;#039;[[Salaria fluviatilis]]&amp;#039;&amp;#039; and &amp;#039;&amp;#039;[[Cobitis paludica]]&amp;#039;&amp;#039; are common in the upper course of the Sistema Ibérico rivers.&amp;lt;ref&amp;gt;{{Cite web |url=http://www.larioja.org/npRioja/default/defaultpage.jsp?idtab=440703 |title=Número de especies y endemismos |access-date=2011-06-20 |archive-date=2013-06-19 |archive-url=https://web.archive.org/web/20130619054308/https://www.larioja.org/npRioja/default/defaultpage.jsp?idtab=440703 |url-status=dead }}&amp;lt;/ref&amp;gt; Some mountain streams have been stocked with [[trout]].&amp;lt;ref&amp;gt;[http://www.conmosca.com/modules.php?name=Content&amp;amp;pa=showpage&amp;amp;pid=23 Mapa de la trucha del Sistema Ibérico] {{webarchive|url=https://web.archive.org/web/20120325223100/http://www.conmosca.com/modules.php?name=Content&amp;amp;pa=showpage&amp;amp;pid=23 |date=2012-03-25 }}&amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Traditional [[cattle]] rearing activities, formerly so important in central Iberia, still survive on dry grasslands in certain villages around the system. There are also many [[hunter]]s visiting some of the ranges, mainly those that are relatively closer to the urban areas and especially on weekends.&amp;lt;ref&amp;gt;[http://www.marm.es/es/biodiversidad/temas/red-natura-2000/ES2430102_tcm7-153810.pdf MARM / Biodiversidad - Sierra de Vicort] {{webarchive|url=https://web.archive.org/web/20110807233517/http://www.marm.es/es/biodiversidad/temas/red-natura-2000/ES2430102_tcm7-153810.pdf |date=2011-08-07 }}&amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
===Vegetation===&lt;br /&gt;
Some ranges have forested patches, consisting mainly of &amp;#039;&amp;#039;[[Pinus pinaster]]&amp;#039;&amp;#039;, &amp;#039;&amp;#039;[[Pinus sylvestris]]&amp;#039;&amp;#039; and &amp;#039;&amp;#039;[[Pinus uncinata]]&amp;#039;&amp;#039; pines and &amp;#039;&amp;#039;[[Quercus rotundifolia]]&amp;#039;&amp;#039;, &amp;#039;&amp;#039;[[Quercus pyrenaica]]&amp;#039;&amp;#039; and &amp;#039;&amp;#039;[[Quercus faginea]]&amp;#039;&amp;#039; oaks, even &amp;#039;&amp;#039;[[Fagus sylvatica]]&amp;#039;&amp;#039; beeches and &amp;#039;&amp;#039;[[Betula pendula]]&amp;#039;&amp;#039; birches grow in some humid slopes, where &amp;#039;&amp;#039;[[Pteridium aquilinum]]&amp;#039;&amp;#039;, &amp;#039;&amp;#039;[[Polypodium vulgare]]&amp;#039;&amp;#039; ferns may also be found.&lt;br /&gt;
&lt;br /&gt;
Other ranges are rocky and quite bare with [[heath]] (&amp;#039;&amp;#039;[[Erica arborea]]&amp;#039;&amp;#039;, &amp;#039;&amp;#039;[[Erica vagans]]&amp;#039;&amp;#039;, &amp;#039;&amp;#039;[[Calluna vulgaris]]&amp;#039;&amp;#039;), [[Broom (shrub)|broom]] as well as [[Thymus (plant)|thyme]] and &amp;#039;&amp;#039;[[Festuca]]&amp;#039;&amp;#039; and &amp;#039;&amp;#039;[[Nardus stricta]]&amp;#039;&amp;#039; grasslands. Thin forest or [[shrubland]] may include &amp;#039;&amp;#039;[[Juniperus communis]]&amp;#039;&amp;#039;, &amp;#039;&amp;#039;[[Juniperus thurifera]]&amp;#039;&amp;#039;, &amp;#039;&amp;#039;[[Cytisus purgans]]&amp;#039;&amp;#039;, &amp;#039;&amp;#039;[[Erinacea anthyllis]]&amp;#039;&amp;#039; and [[Calluna vulgaris|&amp;#039;&amp;#039;Calluna vulgaris&amp;#039;&amp;#039; shrub]]. Often the southern slopes are drier than the northern ones and may be subject to [[wildfires]] in periods of prolonged drought, especially in the summer.&lt;br /&gt;
&lt;br /&gt;
[[Bog]]s are not common in the Iberian Peninsula, but high altitude bogs form in the few areas of the Sistema Ibérico where the water remains stagnant, such as near [[Orihuela del Tremedal]], [[Bronchales]] and in the place known as &amp;#039;&amp;#039;Fuente del Hierro&amp;#039;&amp;#039;, at an altitude between 1.400 and 1.550 m. The plants growing in these bogs are mainly &amp;#039;&amp;#039;[[Polytrichum]]&amp;#039;&amp;#039; mosses, &amp;#039;&amp;#039;[[Potentilla erecta]]&amp;#039;&amp;#039;, &amp;#039;&amp;#039;[[Pinguicula vulgaris]]&amp;#039;&amp;#039;, &amp;#039;&amp;#039;[[Vaccinium myrtillus]]&amp;#039;&amp;#039;, &amp;#039;&amp;#039;[[Calluna vulgaris]]&amp;#039;&amp;#039;, and also &amp;#039;&amp;#039;[[Drosera rotundifolia]]&amp;#039;&amp;#039;, a [[carnivorous plant]] that does not grow further south in Western Europe.&lt;br /&gt;
&lt;br /&gt;
&amp;#039;&amp;#039;[[Centaurea pinnata]]&amp;#039;&amp;#039; is an [[endangered species]] of plant present in the [[Sierra de Vicort]] and [[Sierra de Santa Cruz, Aragon|Sierra de Santa Cruz]] mountain ranges.&amp;lt;ref&amp;gt;[http://derutas.wordpress.com/parajes/sierras/sierra-vicor/ De Rutas - Sierra de Vicor] {{webarchive|url=https://web.archive.org/web/20110528225516/http://derutas.wordpress.com/parajes/sierras/sierra-vicor/ |date=2011-05-28 }}&amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
==Mountain ranges==&lt;br /&gt;
The Sistema Ibérico comprises several mountain ranges and massifs:&lt;br /&gt;
*&amp;#039;&amp;#039;&amp;#039;Northern&amp;#039;&amp;#039;&amp;#039;: [[Sierra de Mencilla]], [[Sierra de la Demanda]], [[Sierra de Neila]], [[Mesa de Cebollera]] and the [[Picos de Urbión]] in the northwest, the [[Sierra de Alcarama]], [[Sierra de Peñalmonte]], [[Sierra de Moncalvillo]] and the isolated [[Moncayo Massif]] in the north, always crested with snow in the winter, with its eastern prolongation the [[Sierra de Nava Alta]].&lt;br /&gt;
*&amp;#039;&amp;#039;&amp;#039;Western&amp;#039;&amp;#039;&amp;#039;: Smaller and drier mountain ranges close to the transition area with the Sistema Central, such as [[Sierra de Perdices]], [[Sierra Ministra]], [[Sierra de Caldereros]] (Águila 1,443 m), [[Sierra de Pardos]], [[Sierra de Miñana]],  [[Sierra de Solorio]], [[Sierra de Selas]] (Aragoncillo 1,517 m) and [[Parameras de Molina]] (Mojón Alto 1,408 m).&lt;br /&gt;
*&amp;#039;&amp;#039;&amp;#039;Central&amp;#039;&amp;#039;&amp;#039;: Numerous mountain ranges located at the heart of the system, such as [[Sierra de la Virgen]], [[Sierra de Vicort]], [[Sierra de Algairén]], [[Sierra de Santa Cruz (Aragon)|Sierra de Santa Cruz]], [[Sierra de Cucalón]], [[Sierra de Herrera]], [[Sierra de San Just]], [[Sierra de Lidón]] and [[Sierra Palomera]], among others.&lt;br /&gt;
