  1. Bird monitoring in six agriculturally dominated landscapes of Saxony-Anhalt (Germany) in 2014

    Frenzel, Mark; Höhne, René
    Bird communities in agriculturally dominated landscapes in Saxony-Anhalt (Germany) were monitored according to the point count method (see Bibby, C.J. (2000) Bird census techniques. Academic Press, London). A central core area of 3 × 3 km within each sample site was divided into five square cells of 1 km**2 each according to a checkerboard grid. Within each of these 5 cells, 4 observation points were selected and at each point all singing, calling and seen bird species were registered within a radius of 250 m for 5 minutes. Surveys started around sunrise and ended about three hours later. A bird...

  4. TERENO (Terrestrial Environmental Observatories) bird monitoring in six agriculturally dominated landscapes of Saxony-Anhalt (Germany)

    Frenzel, Mark; Höhne, René
    In 2001 we started as part of the EU FP5 project Greenveins monitoring of bird communities in the normal landscape of Saxony-Anhalt (Germany) dominated by agricultural use. We selected four landscape sites of 4x4 km (Friedeburg (FBG), Schafstaedt (SST), Greifenhagen (GFH), Wanzleben (WAN)) and recorded birds according to the point count method (see Bibby, C.J. (2000) Bird census techniques. Academic Press, London). A central core area of 3 × 3 km within each sample site was divided into five square cells of 1 km² each according to a checkerboard grid.

    Frenzel, Mark; Dussl, Franz; Höhne, René; Nickels, Volker; Creutzburg, Frank
    Wild bee species abundance based on combined flight traps (yellow funnels with perspex windows) placed at ecotones between semi-natural habitats and agricultural fields. Design: six agricultural dominated landscapes of 4x4 km with one trap per square km in Saxony-Anhalt (Germany), activity of traps in late spring-early summer (three sampling rounds) and late summer (three sampling rounds).

  14. TERENO (Terrestrial Environmental Observatories) wild bee monitoring in six agriculturally dominated landscapes of Saxony-Anhalt (Germany)

    Frenzel, Mark; Preiser, Christine; Dussl, Franz; Höhne, René; Nickels, Volker; Creutzburg, Frank
    In 2001 we started as part of the EU FP5 project Greenveins monitoring of insect communities in the normal landscape of Saxony-Anhalt (Germany), which is dominated by agricultural use. We selected four landscape sites of 4x4 km and recorded insects using combined flight traps, combining the ideas of window and yellow pan traps (see Duelli et al., 1999). Traps consist of a yellow funnel (25 cm diameter) filled with water (preserving agent added) and two perspex windows mounted in a way that they are crossed in the center. Within each square km of a site one trap was placed at...
