Résumé
Biodiversity is now often used to argue PDO device. This research analyzes the links between forage systems, practices and biodiversity in the area of PDO cheese St Nectaire in France. A statistical analysis characterizes the forage systems of dairy farms of the area as regards their potential impact on biodiversity. Surveys in farms and assessments of floristic and faunistic diversity permit to evaluate the level of biodiversity in pastures. This work shows that behind an average level of biodiversity, differences may be important between farms and between plots of one farm, according to the adaptation of his practices by the stockbreeder.
