J.A. Sesé, M. Razin, J. Ruiz-Olmo and L.M. González for their help and support during these
years. To all the forestry rangers and people involved in the monitoring of the bearded vulture
population. The comments of two anonymous reviewers improved the first draft of this chapter.
Finally, thanks to J. Catalan and M. Aniz for the invitation to contribute in the “The High
Mountain in a changing world: challenges for conservation” workshop.
