The French Environment and Energy Management Agency (ADEME) launched in 2004 a national
call for proposal to develop and test soil bioindicators. The main objectives of the programme
were to (i) develop methods for measuring soil biodiversity and soil functions, (ii) use soil
bioindicators to monitor soil quality and (iii) identify relevant bioindicators or endpoints for
ecological risk assessment of soil contamination.
From 2004, 19 projects or PhD thesis aimed to develop and test in different situations
bioindicators based on the following biological organisms:
- Bacteria and fungi (indicators based on the diversity and activity),
- Collembola and Nematodes (indicators based on the diversity),
- Earthworms and total macrofauna (indicators based on the diversity, activity,
bioaccumulation and biomarkers),
- Snails (indicators based on the bioaccumulation),
- Birds and micrommals (indicators based on bioaccumulation and biomarkers)
- Plants (indicators based on the diversity, bioaccumulation and biomarkers).
Depending on the projects indicators are being tested in different situations combining different
soil types, landuses and practices: forest soils, organic farming, pastures, contaminated sites,
remediated soils. Investigation scales varied from mesocosms and field samples to regional
(e.g. landscape sampling) and even national sampling campaigns (e.g. based on the French
national monitoring network).
Based on the results obtained by all research teams and on the multivariate analysis of several
descriptors for each indicator it was possible to select batteries of indicators relevant for our
main objectives (i.e soil monitoring and ecological risk assessment of contaminants). These
batteries are now being tested on common pilot sites varying in soil types, soil contamination
and landuse. This last step currently started is needed to validate our batteries of indicators.
