Caractérisation des communautés d'oiseaux et de chauves-souris dans les parcs urbains d'Aix-en-Provence

Abstract : In ever larger and denser cities, spaces with a nature character provide ecosystem services, enable biodiversity conservation and are meeting places for humans and non-humans. It is therefore key for decision-makers, city designers and city managers to be able to rapidly characterise the biodiversity housed in these spaces in order to reconcile the population’s expectations and environmental issues in development projects and management methods. Here, we aim to identify the factors determining the species assemblages observed in the 10 parks of the city of Aix-en-Provence (characteristics of the parks, management methods, types of urban context), and this for two taxa with different ecological requirements: avifauna and chirofauna. We contacted 39 species of birds. Bird communities become more homogenous from the periphery to the city centre, and the richest communities are found in the larger parks, with a greater diversity of habitats and surrounded by more greenery. We also recorded more than 53,000 passings of bats, indicating a rather high level of activity for urban Mediterranean parks. There is a very strong heterogeneity of activity between parks, which is not explained by the characteristics of the parks. The park with the highest activity rate is a medium-sized park embedded in the dense city. Our results confirm that the question of biodiversity in the city must be asked by considering several spatial scales and several taxa. The habitat potential and vegetation cover in and around the park is a critical dimension for the planning and management of the city.
