In the current biodiversity crisis, conservation scientists are urgently asked to involve themselves in education and communication initiatives toward non-scientists, who are considered as lacking knowledge to correctly value biodiversity. This is particularly argued in urban areas.In this paper, we showed however with an anthropological survey that urban citizens do express a variety of relations toward surrounding urban nature. Then, in an independent survey, we showed that these ways of being connected with nature were shared by students in conservation sciences. Conservation scientists and non-scientific city dwellers have therefore much more in common than is taken for granted in their relations and perceptions of urban nature, notably concerning emotional, sensorial and memorial relationships. Acknowledging these common features in the scientific community could improve the communication between science and the general public about urban nature, help bridge the gap between science and the society and eventually participate to build a new social contract on nature.
