This dataset relates to the 500-ENI network, which is funded by the French Ministry of Agriculture, in order to monitor the unintended effects of agricultural practices on biodiversity. It contains compositional floristic data, as well as climatic, edaphic, landscape and agricultural data at the scale of France in 462 agricultural field margins and at different spatial resolutions. These data and the R script associated, allow to reproduce the analyses described in the paper “Scale dependence in agricultural drivers of field margin plant communities: influence of spatial resolution and extent”, in particular the SARs and GDMs at all resolutions and for each biogeographic region.

The “Data” folder includes floristic and environmental data by plot, but also for all grid positions. The “Spatial_objects” folder provides spatial objects to be imported into R to implement SARs and GDMs. For the sake of confidentiality, the geographical coordinates of the plots cannot be supplied and we have therefore opted for the use of distance matrices. The “Shapefiles” folder contains the different grid positions for all resolutions. Finally, the “Output” folder contains the output files obtained from the R Markdown script. This script only reproduces the raw results, but does not allow to visualize them graphically. The barplots displayed in the paper must be reproduced independently.
