Numerous municipal specialists, experts, representatives of organizations and associations, landscape architects and, of course, arborists and tree workers will meet. The main focus of the conference is on alleys and their road safety, imported vermin like the Asian Long-horned Beetle, new tree diseases like the Ash Shoot Dieback and last but not least rope climbing technique. For the first time ever there will be a panel discussion on the topic “Are alleys facing a final end?”
