This reserve is managed through an agreement with the council of Camargo.
FNyH has begun to acquire land rights in this area in order to restore the environment of the Pendo Cave. The karst singularity of the place is mainly focused on the cave complex of El Pendo-Los Covachos of Peñajorao.
The Pendo is an area with many peculiarities due to its wide endokarst, its flora and fauna, with some endemic species, particularly relict species adapted to the caves. The existing set of caves are in themselves a habitat of Community interest, like the forest of oaks (Quercus ilex ilex) in the Sierra.
Another fact to highlight in the Sierra is the existence of a major karstic aquifer which flows towards fluvial coastal ecosystems of river Pas and the Ría of Boo-Bay of Santander. The outer surface is partially covered with fragments of relict Cantabrian holm oak, dated back from the Tertiary period. Besides its underground wealth, Sierra del Pendo and Peñas Negras has an important external forest wealth. Both places constitute the same geographical unit, fragmented by quarries, timber extraction and communication routes. Thus, a differentiated management of the areas in a coherent relationship is required. Mixed forests, Atlantic meadows and holm oak appear with considerable representation, especially taking into account they are located in the vicinity of Santander. This natural mosaic hosts a varied fauna such as badgers, squirrels, hawks, owls … It is worth stressing that the Sierra de Peñas has a portion corresponding to Escobedo de Camargo, municipality with which it is working to establish management agreements.
It has small enclaves of interest, related to cultural and/or natural values, including areas of access to natural caves, as well as some archaeological and natural points of interest.
