Ordinary biodiversity corresponds to common species and landscapes that contribute to the proper functioning of ecosystems by providing services to humans. Intensification of agricultural practices from the last 50 years has contributed to destroy the ecosystem balance. Availability of relevant indicators is implicitly required for taking account of ordinary biodiversity in the agricultural process. Landscape components are identified by a variety of agro-ecological infrastructures (AEI) but also by their spatial organization in agricultural land and their density. These AEIs are fixed elements of the landscape as non-productive part of the agricultural exploitation and can provide many ecosystem services. The study was conducted in three regions contrasted by their soil, their geographical position of farming systems conditions and landscapes: the Lorraine/Champagne-Ardenne (semi-continental climate), BasseNormandie (oceanic climate) and Auvergne (mountain climate). In each region, farms were selected according to two axes: intensity of agricultural practices on permanent grassland and importance of AEI on their territory. Analysis of these data shows that the species richness of flora and fauna species is dependent on both agricultural practices but also components of the territory and the very structure of the parcel. The first lesson brought by the statistical analysis shows us that species, especially fauna do not response to the same factors. Thus, ordinary biodiversity prediction model offers possible extension outside the areas studied in the project with many precaution. Finally, an overall assessment (BioTEX) at three spatial scales was developed to identify the necessary components to host species and practices with positive impact on biodiversity.
