    Question: Spontaneous succession is the most natural and cost‐effective solution for grassland restoration. However, little is known about the time required for the recovery of grassland functionality, i.e., for the recovery of reproductive and vegetative processes typical of pristine grasslands. Since these processes operate at different scales, we addressed the question: do reproductive and vegetative processes require different recovery times during spontaneous succession? Location: Kiskunság sand region (Central Hungary). Methods: As combinations of plant traits can be used to highlight general patterns in ecological processes, we compared reproductive (pollination‐ and dispersal‐related) and vegetative (growth form) traits between recovered grasslands of different age (<10 years old; 10–20 years old; 20–40 years old) and pristine grasslands. Results: During spontaneous succession, the reproductive trait spectra became similar to those of pristine grasslands earlier than the vegetative ones. In arable land abandoned for 10 years, pollination‐ and dispersal‐related trait spectra did not show significant difference to those of pristine grasslands; anemophily and anemochory were the prevailing strategies. Contrarily, significant differences in the growth form spectrum could be observed even after 40 years of abandonment; in recovered grasslands erect leafy species prevailed, while the fraction of dwarf shrubs and tussock‐forming species was significantly lower than in pristine grasslands. Conclusions: The recovery of the ecological processes of pristine grasslands might require different amounts of time, depending on the spatial scale at which they operate. The reproductive trait spectra recovered earlier than the vegetative one, since reproductive attributes first determine plant species sorting at the regional level towards their respective habitats. The recovery of the vegetative trait spectrum needs more time as vegetative‐based interactions operate on a smaller spatial scale. Thus, vegetative traits might be more effective in the long‐term assessment of restoration success than the reproductive ones

    International audienceSpecies-rich dry grasslands in Europe have suffered losses in extent and diversity in the last 50 years. Their conservation requires maintenance of remaining grasslands and restoration of lost or damaged grasslands. We report on landscape-level restoration studies and case studies from dry grasslands in contrasting regions of Europe to discuss the strengths and weaknesses of the approaches, the results achieved and the costs and benefits. We conclude that landscape-level restoration offers exciting new opportunities to restore biodiversity and landscape connectivity in Europe’s dry grasslands. There are now drivers for large-scale restoration written into the 2020 targets of the Convention on Biological Diversity and the European Biodiversity Strategy. However, a more integrated approach to large-scale ecological restoration is needed for the development of policy tools to achieve the greatest benefits from restoration at the landscape scale
