Diversity and abundance of bees at TERENO sites (2010, 2011): Friedeburg, Greifenhagen, Schafstaedt, Wanzleben

The data are gathered within the TERENO (Terrestrial Environmental Observatories) long-term research programme involving several Helmholtz Association Centers in Germany (www.tereno.net).  TERENO aims to catalogue the longterm ecological, social and economic impact of global change at regional and landscape level. The biodiversity part of TERENO 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), (4) Birds (highly mobile, sensitive to landscape context, integrative at landscape scale).This dataset covers data about bees trapped within 4x4 km landscapes in Saxony-Anhalt (Germany) dominated by agricultural use. The trapping is done 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 May-June and August-September each year.
