We welcomed participants to the large farmyard of Cascina San Francesco and then guided them on a night walk inside the Bosco della Collina di San Giustino. A successful BAT NIGHT that saw the participation of 48 adults and children and the placement on large trees of the first 5 Bat-houses, essential for providing a suitable refuge for these mammals. The event was sponsored by Italcementi and the Municipality of Castenedolo, and received the truly articulated and fundamental collaboration of the La Collina dei Castagni Association and the Campo NUG Association. It ranks among the dissemination initiatives favored by EUROBATS, and is among the activities planned by our project "In search of the off-key note"
