The sites Friedeburg, Greifenhagen, Harsleben, Schafstädt, Siptenfelde and Wanzleben are part of the TERENO Harz / Central German Lowland Observatory in Saxony-Anhalt run by the Helmholtz Centre for Environmental Research UFZ. These sites have a focus on biodiversity monitoring in the “normal landscape” which is characterized by agricultural use (about 60 % coverage of Saxony-Anhalt). Each site is a 4x4 km landscape of mainly arable land and semi-natural habitats like e.g. hedges and forests. The site Friedeburg is close to the river Saale and about 20 km northwest of the city of Halle (Saale). It is characterized by a distinct topography with valleys and slopes with a mean elevation of 122 m asl. Accordingly the average size of crop fields is lowest compared to the other sites, but the total area covered by crop fields is still 71 % and all semi-natural habitats summing up to 10 %.
