Lectures

Alleys, current tree diseases and drought stress

On all three days, the expert presentations focused on trees along streets or on urban sites. The main focus was on presenting possible solutions for dealing with climate-related challenges. This focus was supplemented by practical indoor and outdoor demonstrations.

The three-day conference brought together experts and practitioners from various fields. The aim was to share and discuss the latest findings. The contents of the presentations can be read in the Yearbook of Arboriculture 2022 (Jahrbuch der Baumpflege 2022).
