Diversity and abundance of bees at TERENO sites (2011): Friedeburg, Greifenhagen, Harsleben, Schafstaedt, Siptenfelde, Wanzleben

The data are gathered within the TERENO (Terrestrial Environmental Observatories) long-term research programme involving several Helmholtz Centers in Germany (www.tereno.net). TERENO aims to catalogue the long-term ecological, social and economic impact of global change at regional and landscape level. The biodiversity part of TERENO implemented in the TERENO Harz/Central German Lowland observatory deals with monitoring and research on different organism groups: (1) Vascular plants (primary producers, overall biodiversity indicators), (2) Bees and Hoverflies (important pollinators; ecosystem service agents), (3) Butterflies (indicators for habitat quality, pollinators) and (4) Birds (highly mobile, sensitive to landscape context, integrative at landscape scale).
The dataset covers data about bee communities within 4x4 km landscape sites in Saxony-Anhalt (Germany) dominated by agricultural use. Insects were trapped with combined flight traps (combination of yellow pan trap and transparent perspexes) placed at ecotones (transition zone between arable fields and semi-natural habitats) in late spring-early summer (April-June) and after a summer break in late summer (July-September). The dataset is part of ongoing yearly monitoring.
