Bee species and numbers caught by coloured pan traps across 20 landscapes in 2012, The Netherlands

Data Records

The data in this sampling event resource has been published as a Darwin Core Archive (DwC-A), which is a standardized format for sharing biodiversity data as a set of one or more data tables. The core data table contains 232 records.

1 extension data tables also exist. An extension record supplies extra information about a core record. The number of records in each extension data table is illustrated below.

This IPT archives the data and thus serves as the data repository. The data and resource metadata are available for download in the downloads section. The versions table lists other versions of the resource that have been made publicly available and allows tracking changes made to the resource over time.

Sampling Methods

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 step description:

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.
