All vascular understory plants were sampled in 10 50cm x 50 cm plots located along a transect placed in the middle of the crop field. Sampled plots are 5 m apart from each other. The taxonomic standardization was based on Flora europaea (Tutin et al., 1993). Some taxa were identified only to genus as their identification at the seedling stage may show great discrepancy between observers. Field work was carried out from May to July. Note that not all crop fields were surveyed in 2015.
