Adapting to climate change: Roads department plants sustainable street trees along the L1131 near Horrheim and the K1696 near Kleinglattbach

The sustainability of tree populations in the context of climate change is also posing ever greater challenges for the district council's roads department: The strong effects of climatic changes are making themselves felt in particular through ever new tree diseases, such as ash dieback or sooty bark disease on maples, and through drought damage. As a result, damaged trees along the road network had to be felled again in the 2020/2021 winter half-year in order to maintain road safety. Damaged ash trees and unsuitable trees on the embankments of the L1131 near Horrheim and the K1696 near Kleinglattbach also had to be cleared. These areas have now been planted with new trees by the roads department.

The selection of tree species was based on the classification of woody plants according to their adaptability to climate change: winter lime trees and service trees are considered warmth-loving and are classified as future trees. In contrast to forest stands and projects within built-up areas, only native tree species may be planted in the open countryside in accordance with the requirements of the Federal Nature Conservation Act.

The Roads Department plants new trees along the road network every year. In most cases, existing rows of trees are supplemented or fruit trees that have fallen out are replaced. In this way, the Roads Department also endeavors to respond to the various changes caused by climate change and to replant trees in the course of green maintenance campaigns.
