THE FRENCH NATIONAL SOIL QUALITY MONITORING NETWORK (RMQS) AS A SUPPORT FOR MONITORING SOIL BIODIVERSITY: past, present and future programs

Soil biodiversity would represent about 25% of the species on Earth. It is threatened, and although it is essential for human activities, it remains largely unknown. The French National Soil Quality Monitoring Network (RMQS) has a significant impact in removing the grey areas through its programs on soil microorganisms, soil meso and macrofauna, meadow flora, truffles and more recently enzymatic activities. The first distribution maps of bacterial phyla on a national scale and of soil fauna on a regional scale (in Brittany) have been developed. For the white truffle, three new areas of presence have been identified in France. The habitats of the bacteria were also described for the first ti…

A soil biodiversity survey coupled with the national soil quality monitoring network?

International audience; Despite its importance for human activities, soil biodiversity remains largely unknown and threatened. Aware of the need for large-scale monitoring, we studied the feasibility to add a soil biodiversity survey (RMBS-Biodiversity) to the already existing French soil quality monitoring network (RMQS). We worked with soil biodiversity experts to couple RMBS-Biodiversity with RMQS i.e. to choose soil taxons and functions, the methodologies and the sampling design. According to the experts, the sampling design of RMQS fits with a soil biodiversitysurvey. We propose sampling protocols for i) bacteria and fungi, ii) protists, iii) nematodes, iv) mesofauna (particularly spri…

How to add a biodiversity survey to an already existing national pedologic survey? Case study of the french soil quality monitoring network

International audience; Despite its importance for human activities, soil biodiversity remains largely unknown. This gap of knowledge is a strong limit for studies including it such as in the agricultural field. Particularly, in France, no large-scale monitoring of soil biodiversity exist for the moment except for microorganisms (bacteria and fungi). Aware to this need, with the support of OFB, we studied the feasibility to add a soil biodiversity survey (RMQS-Biodiversity) to the already existing French soil quality monitoring network (RMQS). It is a systemic monitoring based on a 16*16 km grid where the sampling is done on a plot at the center of the mesh, which could belong to different …

Relevance of different soil fauna and microflora groups in the monitoring of soil biodiversity: RMQS-Biodiv, a french Pilote area experience

affiche, résumé; Soil biota play essential roles in delivering key ecosystem goods and services, and are both directly and indirectly responsible for acting in many important functions (nutrient release, soil structure maintain, contribution to water storage). It is thus essential to characterize both the species diversity and the biological functions. In order to monitor soil biodiversity (species and function) in relation to land use (mainly agricultural practices) and pedoclimatic parameters, a French program « RMQS-biodiv » was developed at a wide regional scale (Brittany). An important national research collaboration (12 research teams) supported the program, that undertook the study o…

Démarche statistique pour la sélection des indicateurs par Random Forests pour la surveillance de la qualité des sols

The volume of data, and the large number of biological variables to be tested (one hundred), require analytical techniques, such asRandom Forests, which can overcome the problem of multi-colinearity for the selection of indicators, sensitive to various factors.Random Forests methodology is appropriate for the selection of the most discriminant variables. So, we searched for the best wayto select them, by bringing together all biological variables, representing the Microflora and Fauna. This approach focuses on impactindicators from the Bio2 program, indicators of flora and indicators of accumulation (snails) were not included.This work has been implemented on the three factors of discrimina…

Effets de l’apport de composts sur la biodiversité des sols

National audience; Les sols remplissent des services écosystémiques indispensables à la vie humaine parmi lesquels celui d’approvisionnement en aliments et de régulation, par le stockage, la transformation et le transfert, de l’eau et des éléments tels que le carbone, l’azote, etc.. La matière organique est un élément déterminant du maintien de ces services de par son incidence sur la structure physique des sols, leurs caractéristiques chimiques et leur activité biologique. De fait, si le retour au sol de la matière organique issue du compostage des déchets et des produits résiduaires organiques est une pratique ancestrale, son intérêt ressurgit aujourd’hui face aux défis démographiques, al…
