Soil quality - Sampling of soil invertebrates - Part 1: Hand-sorting and extraction of earthworms

This document specifies a method for sampling and handling earthworms from field soils as a prerequisite for using these animals as bioindicators (e.g. to assess the quality of a soil as a habitat for organisms).This document applies to all terrestrial biotopes in which earthworms occur. The sampling design of field studies in general is given in ISO 18400?101 and guidance on the determination of effects of pollutants on earthworms in field situations is given in ISO 11268?3. These aspects can vary according to the national requirements or the climatic/regional conditions of the site to be sampled (see also Annex C).This document is not applicable for semi-terrestrial soils and it can be difficult to use under extreme climatic or geographical conditions (e.g. in high mountains). Methods for some other soil organism groups, such as collembolans, are covered in other parts of ISO 23611.
