Climate change and pollen allergy: In the plantation of public spaces, cities and municipalities should take into account people suffering from pollen allergy

Climate change leads to changes in pollen flight. The pollen of hazelnut, alder and birch in particular tend to appear earlier and in higher concentrations. This trend is promoted by the plantation of new birches in town. Until now, there is no recommendation in Germany regarding the new plantation of trees in public spaces that takes into account the needs of pollen allergy sufferers. A proposal which trees to avoid in plantations in cities to prevent the further increase of tree pollen is presented. Also attached is a list of allergologically safe trees that are suitable for cultivation.
