### Landscape Quality Cartography  
This cartography was obtained from the integration of the components of greatest relevance, uniqueness, and importance. In the detailed analysis, the intrinsic and extrinsic quality were considered.  
Intrinsic landscape quality: Based on the cartography of each of the territorial factors considered (Figure 6A-F), the intrinsic quality cartography was obtained (Figure 6G) and classified into five classes from very high to very low quality. Thus, it can be seen that the areas of very high quality correspond to areas of the Duero river, the valleys of the Tormes, Agueda and Huebra rivers, and the inselbergs, i.e., to very localized areas. The high and medium quality areas correspond to valley areas which are sectors with a certain lithological relevance. Finally, the sectors of low and very low quality correspond to erosive surfaces, pediments, sanding zones, and valley bottoms, with a lithology composed of conglomerates, pebbles, sands, and clays.

Extrinsic landscape quality: For its preparation, the cartography of each of the elements of the natural and cultural heritage, as well as the presence of urban settlements (Figure 7A-C), were considered. Like the previous cartography, the extrinsic landscape cartography (Figure 7D) was classified into five classes: the zones of very high, high, and medium extrinsic quality were very specific and coincide in areas where there is some type of protection, such as a special protection area for birds (ZEPA), or due to the existence of urban settlements. The low and very low quality zones are the most extensive, being areas of little interest from the point of view of cultural, biological, and ecological heritage.  
Finally, by applying Equation (3), we obtain the cartography of landscape quality, as shown in Figure 8. This cartography shows that the areas of highest quality occupy 26% of the surface area and correspond to hilly areas such as the Duero river canyon and the valleys of the most abundant rivers (Tormes, Agueda, Uces, and Huebra). They are areas considered to be of special protection for fauna and also with flora protection figures (preferential attention, endangered, regulated use, and vulnerable), with the presence of tree formations and mosaic structure. The medium quality is the largest extension, occupying 39%, and corresponds to valley areas and crags with some form of flora protection. Lastly, the lowest landscape quality is 35% and corresponds to areas such as erosive surfaces, with little biological diversity homogeneous structure and without flora and fauna protection.
