A total of 75 window (30km x 30km) and 59 transect (2km x15km) samples were selected. All samples are related to one or more Natura 2000 sites:
• windows are centred on a Natura 2000 site and may contain other Natura 2000 sites,
• transects are orientated to start from inside a Natura 2000 site and end in a intensively used area. Most transects are located within a window.
