Estudi bioacústic sobre la riquesa i l’abundància d’espècies de ratpenats a l'Espai d’Interès Natural de les Obagues del Corb

Bio-acoustic study on the richness and abundance of bats in the Natural Interest Site Les Obagues del Corb In summer 2021, ultrasound recordings were carried out at 16 points in the Natural Interest Site (EIN) Les Obagues del Corb (Catalonia) in order to determine the composition of chiropteran communities in this protected natural space. We recorded a total of 11 species or phonic groups, with an average of 5.9 species per point and an average abundance of 20%. The most widespread species were the common pipistrelle Pipistrellus pipistrellus and Kulh's pipistrelle Pipistrellus kuhlii, both almost ubiquitous and locally abundant, followed at some distance by the Soprano pipistrelle/Schreiber's bent-winged bat phonic pair Pipistrellus pygmaeus/Miniopterus schreibersii and the serotine Eptesicus serotinus. The greater horseshoe bat Rhinolophus ferrumequinum and the Bbrbastelle Barbastella barbastellus were also relatively well distributed although their abundance was lower. This work reveals the presence of a rich community of chiropterans in the Les Obagues del Corb, and indicates the need for studies and protection from possible impacts in the future.
