 What cultural ecosystem services produced by citizens and which values are associated with? 
Now that the crisis is not only economic, but also social and environmental, the well-being in the urban environment becomes a primary question. In recent years, the solution seems to appear in the nature and the biodiversity that are able to act against pollution and depression for example. Local institutions, as well as the citizens, set up a wide range of ecosystem services, mainly cultural, reintroducing nature, in different forms, in the urban area. Based on a precise definition of these ecosystem services, this article intends to highlight the ecosystem service’s diversity built by citizens and to analyze their impact. In this path, we question the representation of these services, as well as the divergence with local institutions, in order to see if these services are mutual production on the territory of Lyon.
