Restauration à l'échelle du paysage : le salut de la biodiversité des pelouses sèches européennes ?

Abstract

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
