Trees with grassy areas soften summer heat

Trees cool their environment and "heat islands" like Munich benefit from it. However, the


degree of cooling depends greatly on the tree species and the local conditions. In a recent study, scientists at the Technical University of Munich (TUM) compared two species of urban trees.

It is cooler under black locusts, especially on hot summer days. This has significant implications for landscape architecture and urban planning: "Tree species such as the black locust that consume little water can provide a higher cooling effect if they are planted on grass lawns," Dr. Mohammad Rahman from TUM explained. "The surrounding soil remains moister thanks to the trees, the grass dissipates additional heat through the evaporation of water and thus reduces the temperature near the ground." This is an important finding obtained by the team led by Humboldt research fellow Rahman.
