The question of the place of wild nature in cities has emerged in recent years as an ecological issue – cities, in France and in the West more broadly, are adopting action plans to take wildlife into account in urban development -, but also as a cultural issue – city dwellers express an increasingly strong sensitivity to nature in metropolises -, and finally a political one. The specificity of Billebaude compared to other approaches to the question is to go into the detail of questions of environmental management, conflicts of representation and cohabitation, to get out of a sometimes irenic vision of nature in the city. The contributors, from various fields, actively participate in this fragmentation of points of view; they are, among others, Audrey Muratet, ecologist and botanist, Léo Martin, doctoral student at the National Museum of Natural History, and Olivier Winock, founder of the NAT'H association. Finally, this issue has the particularity of highlighting the work of street artists Nadège Dauvergne, Bordalo II, Ruben Carrasco, Jussi TwoSeven and WAR!. These will take part in the Wild Incursions exhibition which will mark the spring 2022 season at the Musée de la Chasse et de la Nature. This mode of artistic intervention outside the spaces usually dedicated to art echoes the question of the organization of cities and what goes beyond them.
