Location of monitoring transects and the study area. Bottom-right map: location of the study area (Catalonia) in Southern Europe along with the Mediterranean region according to Metzger et al.34. Upper-left map: location of selected monitoring transects from the Catalan Breeding Bird Survey (CBBS) and the Catalan Butterfly Monitoring Scheme (CBMS) within the areas mostly covered by natural (or semi-natural) vegetation in the study area. This selection of sites was done in order to minimise the effect of anthropogenic pressures not addressed in this study. See main text for details.
