Data on 2341 grass fields from 100 mountain-area dairy farms in France: agricultural uses and geographical characteristics

Data collected by survey from 100 dairy farmers located in a mountainous area (France), including 72 farmers engaged in the traditional Salers system and 28 farmers engaged in a specialised dairy system. The questionnaire covered all uses of all grass fields during the entire outdoor period, considering ‘field’ as an area that was used in the same way throughout the entire period. Cutting dates, grazing dates, animal categories and numbers were recorded using a grazing and harvesting schedule. We also recorded key geographical and physical characteristics of each field, i.e. main slope, altitude, area, and distance from the farmstead. Each field in the presented database is thus described by 47 quantitative and qualitative variables. Further information on data collection and processing is available in the associated publication in Data in Brief (https://doi.org/10.1016/j.dib.2023.109242).
