Explaining grassland and cultivated land vegetation: relevance of the dynamics of agricultural practices and landscape mosaic

Abstract : The diversity of grassland and cultivated land vegetation is determined by both agricultural practices and landscape mosaic characteristics. Thisstudy, based on a characterization of agricultural practices and surrounding landscape dynamics over a period of 9 years in the form of ‘parceltrajectories’, evaluates their respective impact in the case of a mixed crop-livestock experimental farm in Lorraine. Floristic diversity is characterizedbased on a dual taxonomic and functional approach. This study shows that taking into consideration practices over the previous year seems to bemore effective than a long-term approach. However, it is essential in this case to consider parcel trajectories with regard to surrounding landscapeover the long-term and to characterize vegetation based on a functional approach. This work should help improve forecasting models for vegetation dynamics.
