International audience. Degradation of grasslands is marked by a decrease in plant and insect diversity, biomass and soil composition. Such degradation has significant ecological implications for community stability and ecosystem functioning. Our study focuses on the sub-steppic Mediterranean grassland of the La Crau Plain. The dominant tussok grass species, Brachypodium retusum, was re-established after having manipulated the microenvironement by restoring the natural large stone cover on the soil surface. Twenty years after the experiment was set up, we revisited it with a multi-component approach to evaluate the effects of these treatments in the middle term.
