The main goal of this project is to revert the declining population trend of the European Roller in Portugal. Specific objectives include:

1. Provide a network of nest boxes in the main SPAs with steppe habitat to encourage an increase in the number of couples, reinforce residual breeding nuclei, and enhance the expansion of the distribution area, restoring populations in regions where the species has recently disappeared;

2. Re-establish the long-term population monitoring program to investigate the reproductive and demographic parameters and evaluate the effectiveness of the implemented measures;

3. Conduct a national census to estimate numbers and population trends;

4. Investigate the impact of changes in land use, namely the type and intensity of grazing, on reproductive success;

5. Assess migratory routes and wintering areas to identify potential threats in the non-breeding period;

6. Promote awareness of the public and stakeholders to ensure conditions allowing the preservation of the roller in the long term.
