Map of the study area with position of trap triplets, buffers of 800 m radius (red circles), the three sectors A, B, C (black line for the joint 2 km buffers), and the forest composition. The red square on the map of Spain (top-right map) indicates the localization of the study area. The coordinates of the center of sector A are 41.5028801 and −4.73272942; sector B 41.20447729 and −4.71737119, and C 41.32691005 and −4.54603389, in decimal degrees WGS84
