It is already known that the willows They prefer deep, moist soils, growing luxuriant even in water. This peculiar habitat that they seek is that which allows us to walk along this shore of the Deva under the shade of their canopies, a shadow that in some points becomes impenetrable, when the forest reaches its maximum density.
The banks of the Asturian rivers were populated with the most diverse forests in species. However, as these are environments with high agricultural productivity, a large part of the riverside forests have been cleared. Hence the importance of this willow that continues to grow in the middle reaches of the Deva and that constitutes a fertile plain in optimal condition, more typical of the past.
The river Deva
The banks of the rivers Cuadalosos like the Deva, very appropriate to be flooded by the water, is the place where the most resistant species of willows finally managed to be implanted. Everything is fruit of an adaptation process very long and laborious. The exemplary vitality of the willow of Buelles has been created as a fort, trunk by trunk and little by little; through the passage of time and water. This riparian forest has been defended with nails and teeth thanks to a first potección waist made up of shrubby willows, perfectly adapted to withstand the onslaught of fluvial avenues. After them we find a second waist tree willow trees: probably the largest and best developed of the entire Cantabrian coast.
We are already a little further away from the channel, in areas that do not suffer the mechanical effect of the flood but that are periodically flooded by the waters. Here is dominant the white willow (Salix alba), a species of great size. Usually these more interior willows have been one of the environments that have suffered the most human aggression, given the extreme fertility of the soils on which they settle. In Buelles, however, this aggression is not known, turning it into a riverbank of exceptional natural and patrimonial interest.
El Fauna interest It is also considerable. There are breeding colonies of sapper (Riparia riparia) in the area, and otters (Lutra lutra) and lamprey (Petromyzon marinus) are also common. These species are included in the Regional Catalog of Endangered Species of Asturian Wildlife.
In addition, other interesting and bioindicating species of water quality are present, such as Atlantic salmon (Salmo salar) and desman (Galemys pyrenaicus).
