The ecosystem services (ES) approach has been introduced in environmental policies and management to serve as a link between nature and society. Communication, education, and participation actions (CEPA) have the potential to facilitate this link. In this research, we evaluated how CEPA have been implemented in biodiversity conservation projects that consider ES. We used content analysis to review 182 biodiversity conservation projects executed by 33 environmental authorities in Colombia. We also used multiple correspondence analysis and cluster analysis to classify projects on the basis of the purpose of CEPA, type of CEPA, integration of CEPA, ES addressed, main stakeholders, and aim of conservation. We found that five aspects are key to fostering social engagement in environmental management projects: promoting explicit consideration of the ES approaches, increasing conservation efforts focused on the non-material benefits of the ES, integrating different types of CEPA, including overlooked key actors (e.g., indigenous communities and women), and developing and implementing social indicators. These considerations might lead environmental managers to revise their daily practices and, eventually, inform policies that foster an explicit link between CEPA and ES approaches.
