C-B-A, culture - biodiversiy - amenities: these are the 3 basic reasons why tree avenues are protected by the French environmental code (article L350-3). You will find some links towards articles and videos about this protection under the "Resources" tab of our website.
A new paper, "Allées d’arbres en Europe et espèces des Listes rouges – De la connaissance à l’action", written by our managing director, was published last spring by the online scientific magazine VertigO. It deals with the biodiversity in avenues and how to manage them. It is in French, but has an English summary.
