Description
In 1996, a nine-month research program was carried out at Wageningen University in the soil biology department in collaboration with the Wijster Biological Station. The aim was to gain insight into which underground herbivores were present in the grasslands. The monitoring took place on four grasslands that had been taken out of agricultural production, which were no longer fertilized and were mowed annually to preserve the fields. These four lawns have not been fertilized since 1989, 1985, 1972 and 1967 respectively. On each of the fields, a section of 30m x 45m was chosen for the sampling. Pyramid falls were placed a ndmoved every two weeks, each within a section of 10m x 15m so as not to deprive the grass of light for a long time. The soil from places where the pitfalls were dug every fortnight was taken to the laboratory to sort these samples by hand for all kinds of larger arthropods and/or earthworms. Light traps and pot traps, all containing a 2% formalin solution, were emptied weekly. The captured ground beetles were identified to species by employees of the Wijster Biological Station and the other animals were first sorted into order or family. The spiders, harvestmen, beetle larvae, millipedes and centipedes were then identified to species by various specialists.
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 2,898 records.
2 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
Bio-photo eklektors with one lightfall in the top and two pitfalls at ground level, for which the space was created by getting soil out of the grasslands were moved every fortnight. The lightfalls and pitfalls contained formaldehyde solution 2%. Soil samples were taken bi-weekly, lightfalls were emptied weekly and pitfalls were emptied weekly.
| Study Extent | March -December 1996 |
|---|---|
| Quality Control | Identifications of ground beetles were done by personnel of the biological station in Wijster; beetle larvae were identified by Michael Traugeot; weevils were identified by Theodoor Heijermans; click beetles were checked by Alterra; spiders and harvestmen were identified by Aart Noordam; millipedes, centipedes were identified by Matty Berg |
Method step description:
- All identifications, to order, family, genus or species were stored in excel files; these were checked thoroughly. Thereafter, the dataset was generated in GBIF style with the help of an R program.
