Map of Jersey showing study sites (labelled circles), number of ACOs checked in each season (size of circle) and naïve occupancy (dark grey = occupied, light grey = unoccupied). Sites with concentric circles were surveyed in both years. The map was generated in ArcMap v.10.5 (http://arcgis.com) and refined in Inkscape v. 0.91 (https://inkscape.org).
