What are the expectations of the actors – scientific, political or others – who call upon it? Under what conditions can individuals embody it and what effects can they have on their skills or on the recognition and valorization of these skills? We address these questions in a reflexive way, through an a posteriori analysis of a participatory action research experience set up in the framework of a transdisciplinary research project. Our approach is based on a logic of dynamic, relational, situated and distributed competences between the mobilised citizens and the other actors of the project, including the researchers. In a territory marked by a long tradition of environmental management entrusted to an administration supported by scientific experts, an innovative participation mechanism is invoked to co-construct a vision of the sustainable management of a forest territory nourished by citizen proposals. We analyze the different stages of this participatory project, from the selection of a mini-public by drawing lots, to the deliberation of the result of their work, through the gradual constitution of the citizens as an informed collective likely to use its legitimacy to modify the balances and games of actors on the territory.}}
