CASE STUDY 4

The French case study area (CSA) is dedicated to examining the impact of deciduous hedgerows on small mammal biodiversity and mitigation of rodent-borne zoonoses in coniferous forests. This CSA is situated within the Landes pine forest near the Western coast of France, south of the Arcachon Bay. It comprises a network of hedgerows that vary in their connectivity and density. The Landes forest stand as the Europe's largest man-made woodland, predominantly cultivated with maritime pines (Pinus pinaster) for industrial purposes. The relative ecological impoverishment of this forest makes it highly susceptible to risks such as wildfire, wind damage, pests, and diseases. In response to these challenges; the planting of deciduous hedges is considered as a potential solution to enhance biodiversity and mitigate these risks. Hedges are recognized for their capacity to support biodiversity by offering habitats, shelter, and food for various plant and animal species. However, our understanding of the impact of these hedges on biodiversity and health remains scarce. Therefore, our primary aim is to investigate the influence of deciduous hedges on the diversity of small mammals and their ectoparasites (ticks) as well as their role in mitigating zoonotic diseases associated with these animals.
