Air transport stakeholders and scientists are collectively involved in the Aéro Biodiversité association to better preserve airport biodiversity. Groupe ADP has been contributing to the process, since 2014: regular participatory observations are carried out on the aeronautical meadows, with volunteer employees of the Group and the scientific support of the French Natural History Museum. These actions help assess and keep track of the fauna and flora at Groupe ADP’s main airports as well as raise awareness of these issues, while keeping aviation safety a priority.
