RIVM (NL) - Earthworm Observations in Soil Samples

Latest version published by National Institute for Public Health and the Environment (RIVM) on Jul 8, 2015 National Institute for Public Health and the Environment (RIVM)

The dataset contains density data (number per square meter) of earthworms in The Netherlands. The data were collected from 1997 up to and including 2011.

Data Records

The data in this occurrence 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 2,212 records.

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

Soil samples were taken in The Netherlands almost every year from 1997 up to and including 2011. Each year about 40 locations were sampled, several of them more than once, in a five years cycle. Altogether about 390 different locations were sampled in the period 1997 - 2011. Per location six soil samples (cubes of 20x20x20 cm of topsoil) were taken and analyzed for earthworms.

Study Extent n/a

Method step description:

  1. Earthworm density was calculated as number per square meter. The coordinates of the locations are accurate up till 1 km. Higher taxonomic groups (kingdom, phylum, class, order, family) were abstracted form the Fauna Europaea (http://www.faunaeur.org/) database for each species and added to the dataset.
