Biodiversity in urban areas: is species recolonization possible?

Urban agriculture offers many little-known services, including the reconstruction of landscape corridors. The Demonstrator of Urban Agriculture (DemAU), an experimental market gardening site on the roof of the Angers Chamber of Agriculture, is a place for observing biodiversity, in particular through Biological Monitoring of the Territory. After 3 years of experimentation, an inventory of the site was carried out in order to estimate the biodiversity that has naturally returned to colonize the space.
