Long-term mammal survey in pasture fields of the Montaña Palentina Natural Park, Cordillera Cantábrica (Spain)

The censuses were carried out on a fixed route of 53 km out and back along the roads that run along the bottom of the valleys in a selected area of the Montaña Palentina Natural Park. The census took place mainly at morning and evening and lasted between 3-4 hours each. One section of the fixed route of 11.7 km, located in the Castillería valley, was also done at night. Each animal observed was georeferenced using an orthophoto on a tablet. In addition, whenever possible, photos or videos were taken of wildcats and domestic cats (Felis catus). Other mammals recorded were: Red fox (Vulpes Vulpes), European badger (Meles meles), European pine marten (Martes martes), Stone marten (Martes foina), wolf (Canis lupus), Red deer (Cervus elaphus), Roe deer (Capreolus capreolus), Cantabrian chamois (Rupicapra rupicapra), wild boar (Sus scrofa), Broom hare (Lepus castroviejoi) and European hedgehog (Erinaceus europaeus).
