This document specifies a method for sampling, handling and
extracting enchytraeids from terrestrial 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).
Basic information on the ecology of enchytraeids and their use
as bioindicators in the terrestrial environment is included in the
This document applies to all terrestrial biotopes in which
enchytraeids occur. The sampling design of field studies in general
is given in ISOÂ 18400-101. These details
can vary according to the climatic/regional conditions of the site
to be sampled and an overview on the determination of effects of
pollutants on enchytraeids in field situations is given in
Methods for some other soil organism groups such as earthworms
or arthropods are given in ISOÂ 23611-1, ISOÂ 23611-2, ISOÂ 23611-4 and ISOÂ 23611-5.
This document is not applicable for very wet or flooded soils
and might be difficult to use under extreme climatic or
geographical conditions (e.g. in high mountains).
When sampling soil invertebrates, it is highly recommendable to
characterize the site (e.g. concerning soil properties, climate and
land use). However, such a characterization is not covered by this
document. ISOÂ 10390, ISOÂ 10694, ISOÂ 11272, ISOÂ 11274, ISOÂ 11277, ISOÂ 11461 and ISOÂ 11465 are more suitable
for measuring pH, particle size distribution, C/N ratio, organic
carbon content and water-holding capacity.
