The report from Naturalia-Environenment presents the results of :

Monitoring of an experimental “standard gantry” structure for chiropterans on the A83 motorway :

• Acoustic monitoring (trajectography)
• Visual monitoring using a thermal camera

Monitoring of two eco-bridges on the A64 and A89:

• Acoustic monitoring (trajectography)
• Visual monitoring using a thermal camera

Three-year monitoring of two experimental bat bridges on the A89 motorway:

• Acoustic monitoring (classic monitoring)
• Visual monitoring using a thermal camera
• A connection will be made with the acoustic monitoring of other structures on the A89 motorway (wildlife crossing, ecological steppingstones, etc.)

One-year monitoring of two bat bridges on the A89 motorway as part of Fabien Claireau’s thesis :

• Acoustic monitoring (trajectography)
