Cuenca del Esva
  • The Esva Basin is clearly bounded to the west by the Carondio Range and its extension to the coast through the Buseco Range, and to the east by the Tineo Range and the Sierras de los Vientos Range.

  • Plant life

    The Esva Basin Protected Landscape was extensively repopulated with pines in the 1950s and 60s, although there are still many valleys and dales with well-preserved oligotrophic oak groves, accompanied in the shadiest spots by beech. In the northern area, very aged and poorly exploited chestnut trees abound.

    The most representative forest groups are certainly alder. Except the more altered riverbank meadows in Paredes and Brieves, the Esva preserves along its entire course some of the least altered riverbanks in the region. These are home to tropical ferns like the chain fern, a species listed as being of special interest.

    Wildlife

    The main environmental wealth ​​of the Esva Basin Protected Landscape is to be found on its riverbanks and in its watercourses, as also occurs with its wildlife.

    The banks of the River Esva are the most populated among Asturian rivers. Its rich waters are mainly home to salmon and trout, but also eels.

    Besides the species typical to river habitats, this area preserves game populations such as wild boar and deer. The presence of the wolf is not uncommon in the high mountains of the southern edge of the territory.

The Esva Basin Protected Landscape is mainly formed by its riverbanks and riverbeds.

The landscape presents an unvarying siliceous relief, dominated by a repetitive sequence of shale, sandstone and quartzite, now and then accompanied by some rocky areas with limestone and marble formations.

It includes the entire Esva Basin, extending 460 km2 and encompassing its major tributaries (Navelgas, Barcenas, Llorín and Mállene) and the small streams that flow into these rivers.

The River Esva originates from the confluence of the Rivers Barcena and Grande de Calleras, north of Tineo, in the Ese Valley. The Esva Gorges, a listed Natural Monument, rise above the river.

The river is also a destination for lovers of fishing due to the abundance of trout and salmon in its waters, even though it does not have a very high water level.
