Understanding stakeholder perception is crucial for developing effective conservation strategies. Nevertheless, it is usually unclear which aspects are favored by different actors involved in environmental management. 

Here, we surveyed 354 stakeholders from 22 countries across the Mediterranean Basin to identify areas of agreement in their preferences. Despite broad variation in individual choices, we found a general consensus emerging across stakeholder groups (Scientists, Non-Governmental and Governmental Organizations) on preferred ecosystem services, biodiversity facets, protected areas characteristics, and their relative importance. Specifically, our model identifies regulating ecosystem services, taxonomic diversity, and intrinsic value of nature as priorities for stakeholders. Conversely, the preferred characteristics of protected areas (e.g., size, accessibility) vary mostly based on individual preferences. 

We suggest that considering areas of stakeholder agreement when discussing management actions in the Mediterranean Basin will facilitate the adoption of area-based conservation actions expected by the Kunming-Montreal Global Biodiversity Framework. In the Mediterranean Basin, therefore, policy makers should strive to protect areas with high regulating ecosystem services, use taxonomic diversity to engage stakeholders, prioritize ecological targets to different characteristics of protected areas, and maintain the focus of area-based conservation on nature itself. 

Implementing these action points should enhance support for conservation action in the region.
