Scaling up ecosystem restoration is essential to halt and reverse land degradation and biodiversity loss and ensure future functionality and resilience. However, the implementation of concrete restoration initiatives will present many challenges, such as setting appropriate and realistic goals, selecting or developing the most effective and efficient restoration practices, as well as carrying out effective short- and long-term monitoring of success. Furthermore, there is a lack of information to facilitate the implementation of effective restoration interventions. To address this knowledge gap we gathered information on the ecological, economic, social and policy challenges faced by restoration practitioners across Europe using a widely distributed online survey.
