After the second fieldtrip, we have got more than 1000 photographs and about 50 videos of wildlife in the quarry Áridos Sanz in Valladolid. Our 10 camera traps, strategically placed throughout the lagoons and water streams to photograph otters, have recorded, in addition to European otter (Lutra lutra), images of another 15 vertebrate species visiting or living in the quarry: common genet (Genetta genetta), common moorhen (Gallinula chloropus), common raven (Corvus corax), European badger (Meles meles), European roe deer (Capreolus capreolus), grey heron (Ardea cinerea), mallard (Anas platyrhynchos), purple heron (Ardea purpurea), rabbit (Oryctolagus cuniculus), red fox (Vulpes vulpes), northern goshawk (Accipiter gentilis), song thrush (Turdus philomelos), white stork is (Ciconia ciconia), wild boar (Sus scrofa), and a rodent that is difficult to identify. We have not lost the hope of finally confirming the presence of the Southwestern water vole (Arvicola sapidus) with our camera traps because we have found droppings of this species in the quarry and their surroundings. It is unexpectedly fascinating to capture such a high faunal richness in the quarry. These findings show that quarries under a proper management can function as a refuge for many wildlife species and even become a local biodiversity hotspot.
