Híjar River
The Híjar river or The Híjar is a river in northern Spain whose waters give rise to the Ebro, Ebro River. This was accredited as early as 1862 by Pedro Antonio de Mesa in the first known hydrogeographic survey. This river runs more than 20 km from the headwaters of the Hermandad de Campoo de Suso, Campoo Valley, and then part of its flow filters and makes a short subway journey of 800 m, resurfacing along with 4 other springs in the town of Fontibre, then receiving the name of "Ebro". The flow of the Hijar River that is not submerged continues along the surface in an easterly direction and joins the Ebro at Reinosa, a few kilometers downstream. This fact was scientifically demonstrated by technicians from the Geological and Mining Institute of Spain in 1987, after pouring fluorescein into the river, and observing that the same flow filtered by the Híjar was the one that came out dyed in the Fontibre spring. Route to Fontibre and Reinosa The Híjar rises in the Pidruecos basi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ebro Basin
The Ebro (Spanish and Basque ; , , ) is a river of the north and northeast of the Iberian Peninsula, in Spain. It rises in Cantabria and flows , almost entirely in an east-southeast direction. It flows into the Mediterranean Sea, forming a delta in the Terres de l'Ebre region, in southern Catalonia. In the Iberian peninsula, it ranks second in length after the Tagus and second in discharge volume, and drainage basin, after the Douro. It is the longest river entirely within Spain; the other two mentioned flow into Portugal. The Ebro flows through many cities (): Reinosa in Cantabria; Frías and Miranda de Ebro in Castile and León; Haro, Logroño, Calahorra, and Alfaro in La Rioja; Tudela in Navarre; Alagón, Utebo, and Zaragoza in Aragon; and Flix, Móra d'Ebre, Benifallet, Tivenys, Xerta, Aldover, Tortosa, and Amposta in the province of Tarragona (Catalonia). Geography Upper part and tributaries The source of the river Ebro is in the Cantabrian Mountains, in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caddisfly
The caddisflies (order Trichoptera) are a group of insects with aquatic larvae and terrestrial adults. There are approximately 14,500 described species, most of which can be divided into the suborders Integripalpia and Annulipalpia on the basis of the adult mouthparts. Integripalpian larvae construct a portable casing to protect themselves as they move around looking for food, while annulipalpian larvae make themselves a fixed retreat in which they remain, waiting for food to come to them. The affinities of the small third suborder Spicipalpia are unclear, and Molecular phylogenetics, molecular analysis suggests it may not be monophyletic. Also called sedge-flies or rail-flies, the adults are small moth-like insects with two pairs of hairy membranous insect wing, wings. They are closely related to the Lepidoptera (moths and butterflies) which have scales on their wings; the two orders together form the superorder Amphiesmenoptera. The aquatic larvae are found in a wide variety o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ramsar Convention
The Ramsar Convention on Wetlands of International Importance Especially as Waterfowl Habitat is an international treaty for the conservation and sustainable use of Ramsar site, Ramsar sites (wetlands). It is also known as the Convention on Wetlands. It is named after the city of Ramsar, Mazandaran, Ramsar in Iran, where the convention was signed in 1971. Every three years, representatives of the contracting parties meet as the Ramsar Convention#Conference of the Contracting Parties, Conference of the Contracting Parties (COP), the policy-making organ of the wetland conservation, convention which adopts decisions (site designations, resolutions and recommendations) to administer the work of the convention and improve the way in which the parties are able to implement its objectives. In 2022, COP15 was held in Montreal, Canada. List of wetlands of international importance The list of wetlands of international importance included 2,531 Ramsar site, Ramsar sites in Februa ...

Special Protection Area
A special protection area (SPA) is a designation under the European Union Directive on the Conservation of Wild Birds. Under the Directive, Member States of the European Union (EU) have a duty to safeguard the habitats of migratory birds and certain particularly threatened birds. Together with special areas of conservation (SACs), the SPAs form a network of protected sites across the EU, called Natura 2000. Each SPA has an EU code – for example the North Norfolk Coast SPA has the code ''UK9009031''. In the United Kingdom As at 21 September 2006, there were 252 classified SPAs and 12 proposed SPAs in England, Scotland, Wales and Northern Ireland. The Conservation (Natural Habitats etc.) Regulations 1994 implement the terms of the Directive in Scotland, England and Wales. In Great Britain, SPAs (and SACs) designated on land or in the intertidal area are normally also notified as Sites of Special Scientific Interest (SSSIs), and in Northern Ireland as Areas of Special Scientif ...

Sierra De Híjar
The Sierra de Híjar is a mountain range of the Cantabrian Mountains System, located in the Province of Palencia and the Cantabria, Autonomous Community of Cantabria in northern Spain. Geography The range is long, and runs in a west-northwest to east-southeast direction. The highest peaks in the range are concentrated in the northeastern to central section. From there the altitude declines. The rangehas a maximum width of , between Penaguda and Sel de la Fuente. The range's highest point is at the peak of Cuchillón, although its exact altitude differs by source, including: according to the Instituto Geográfico Nacional (Spain), National Geographic Institute of Spain (Instituto Geográfico Nacional); and according to Francisco Hernández-Pacheco and in other publications by the same National Geographic Institute. This system marks the boundary between the regions of Campoo in Cantabria and La Pernia in Province of Palencia, Palencia of Castile and León. It is one of the so ...

Special Area Of Conservation
A special area of conservation (SAC) is defined in the European Union's Habitats Directive (92/43/EEC), also known as the ''Directive on the Conservation of Natural Habitats and of Wild Fauna and Flora''. They are to protect the 220 habitats and approximately 1,000 species listed in annex I and II of the directive which are considered to be of European interest following criteria given in the directive. They must be chosen from the Site of Community Importance, sites of Community importance by the member states and designated SAC by an act assuring the conservation measures of the natural habitat. SACs complement special protection areas and together form a network of protected sites across the European Union called Natura 2000. This, in turn, is part of the Emerald network of Area of Special Conservation Interest, Areas of Special Conservation Interest (ASCIs) under the Convention on the conservation of European wildlife and natural habitats, Berne Convention.
