Description

The dataset contains data on wild bee species and honey bees caught by coloured pan traps across 20 landscapes in two censuses in July and August 2012, in The Netherlands. It concerns data underlying the paper Bukovinszky et al. 2017. Biological Conservation, 214, 312-319.

Sampling Description

Study Extent

Bee species caught by coloured pan traps across 20 landscapes in South and Central Netherlands in July and August 2012.

Sampling

Twenty rectangular 50 ha landscape plots in agricultural areas in the southern and central parts of The Netherlands, scattered across a ca. 10.500 km2 large area. Trapping stations were located at least 100 m apart. A trap consisted of three pans (diameter 12 cm, volume 480 cm3) that were colour-coated using yellow, blue and white, UV-reflecting colours. The pans (one of each colour) mounted on a one-meter-tall wooden pole comprised a single trapping station. Two censuses were carried out in the third weeks of July and August, with traps catching for a period of two days within a census. The material was preserved in ethanol until identification.

Method steps

  1. In each landscape plot, six traps were used. The traps were placed in an open spot (i.e. away from shadow of trees) in comparable vegetation background (i.e. grassy field boundaries) that was slightly lower than the position of the pan traps. When operating, traps were filled with water containing a non-fragant (~0.2 v/v%) surfactant.
