Caceres Natural Reserves
Monfrague Natural Park
Monfrague Natural Park has an area of 17,852 ha. Its limits coincide with those of the SPAB of the same name.
This protected area extends to both sides of the River Tajo, including an estuary and a valuable branch of the River Tjetar.
With a privileged location, it constitutes the Southern closure of the natural region of Campo Arañuelo, forming its mountains in an arc that unites Las Villuercas and the mountains that surround la Vega del Alagón, acting as a real ecological corridor.
Garganta de los infiernos Natural Reserve
Is found at the head of the Valle del Jerte region on the Southeast slope of the Sierra de Gredos. It is the port of entry to Extremadura from the province of Avila, a real observation point to the narrow valley that opens subsequently to Cáceres.
The reduced area of the reserve, 6800 ha. Is distributed between three municipal terminals, Torravacas, Cabezuela del Valle and Jerte.
Sierra de San Pedro
The SCA occupies the majority of the mountainous formations of the Sierra de San Pedro, that make up together with the Sierra de Montanchez and the Villuercas massif, the inverted arc that establishes the dividing line between the basins of the rivers Guadiana and Tajo. The central nucleus of this extensive protected space is made up of low or average altitude Sierras oriented towards the Northeast, that are noted for being surrounded by low land, as is the case of los Llanos de Brozas and Cáceres. The most oriental limit is found in the Sierra de Enmedio, near Cordobilla de Lacara, continuing with the Sierras of los Pajonales, sierra de Alijibe and Sierra de la Umbria, among the localities of Aliseda, Albuquerque, Herreruela, Salorino and Puebla de Obando. The West limit, almost on the border with Portugal, is situated on the Sierra de Santiago, in the locality of Santiago de Alcántara. The less abrupt area of the space is found in the Southeast, coinciding with the pastures gently settled between the River Zapaton valley and the Peña del Aguila reservoir, in Villar del Rey.
This is one of the protected spaces of greatest area and the 115,032 ha it occupies are distributed between the municipal terminals of Badajoz, Villar del Rey, Albuquerque, San Vicente de Alcántara, Valencia de Alcántara, Santiago de Alcántara, Salorino, Herreruela and Aliseda .
Llanos de Caceres - Sierra de Fuentes
An extensive area of plains with soft slopes that extend from Brozas to Trujillo, settled on the Cáceres plains and marked by the mountainous formations of Sierra de San Pedro, the natural closure of the plains. To the North, the Rivers Tajo and Almonte interject in the foothills of the sierra that gives rise to Gredos and Villuercas, giving rise to less abrupt land. Sierra de Fuentes is the main mountainous formation within the plain, like as a large island immersed in the pastures. In the centre of the plains can the Guadiloba reservoir can be found with its peculiar dragon-like form.
The protected space includes the best areas for birds, largely limited by the banks of the Rivers Tamuja and Almonte.
The area of the Special Conservation Area includes somewhat more than 70,000 ha belonging to the municipalities of Cáceres, Sierra de Fuentes, Torreogaz, Torrequemada and Aldea del Cano.
The region of Villuercas and Ibores
Is situated in the southeastern part of the province of Caceres, bordered in the south by the province of Badajoz and in the east by Toledo. The SPAB is surrounded by extensive flat areas or soft mountainous areas, such as the fertile plain of the Tiétar River in Campo Arañuelo to the north, the flatlands of Trujillo in the west or the high fertile plains of the Guadiana in the south, all of them with great environmental and scenic value, giving rise to one of the areas of Extremadura with the greatest biodiversity.
The transversal disposition of the mountain range, oriented towards the northeast and southwest, means that the rivers that sprout up in these valleys flow both into the basin of the Tagus as well as into the basin of the Guadiana. Thus, those which are tributary of the Tagus are the rivers Ibor, Viejas, Almonte and Gualija, and to the Guadiana, the rivers Ruecas, Gargáligas, Guadarranque and Guadalupejo.
The SPAB of Cedillo-Tajo Internacional is situated to the west of the province of Caceres, bordering Portugal. Its boundaries follow the Tagus River and the Sever River, occupying a narrow fringe that includes all the banks of their basins, except in the end section of the Tagus, where the boundaries are broadened and extend broadly through the meadows and slopes that flow into the Sever, and occupying the totality of the municipal district of Cedillo.
The SPAB establishes a continuity with the protected areas of Portugal, where the Tagus River has the category of Natural Park. In Extremadura, this SPAB practically limits with the SAC "Sierra de San Pedro", as well as with the Sites of Community Importance (SCI) "Tio Erjas", "Llanos de Brozas", "Rivera de Aurela" and "Riveras de Carbajo and Calatrucha", stressing the importance of the natural values existing in this privileged corner of the region.
Due to its lineal nature, the surface area of the SPAB "Cedillo-Tajo Internacional" is solely of 13,263 hectares, that are distributed amongst the municipal districts of Cedillo, Herrera de Alcántara, Santiago de Alcántara, Valencia de Alcántara, Carbajo; Membrío and Alcántara .
