   abstract = {In 2012 we began working to determine the distribution and conservation status of Myotis bechsteinii in Aragon. We surveyed 18 sites with potentially suitable habitat in the Aragonese Pyrenees and 231 individuals of 23 bat species were netted. We confirmed the presence of the Myotis bechsteinii in the Aragonese Pyrenees, providing the first data on breeding in Aragón and the northeast Iberian Peninsula. 16 individuals of Myotis bechsteinii were caught in five locations relatively close to each other. Breeding females and juveniles were captured in a single location, which is also a breeding roost located on an old specimen oak Quercus gr cerrioides with large diameter in a monospecific open woodland (dehesa), with dominance of ancient hollow trees. Counting during emergence showed that the colony was formed by 64 females and juveniles. We only trapped adult males in the other localities sample all of them within or in the vicinity of well-preserved spots Quercus

gr cerrioides. The oak forests are highly degraded in Aragonese Pyrenees, with very few and small patches of healthy forest with adult specimens. This results in a very low habitats suitability for Myotis bechsteinii and a high degree of fragmentation.},
