The birch continues to be a burden in Vorarlberg!

The coming days will be mild and sunny in Vorarlberg. This will allow the pollen count to develop unhindered, which means a high level of stress for allergy sufferers. On Thursday, Sahara dust could also exacerbate the situation. Currently the birch is currently the most important allergen in the air. Rainfall is expected from Sunday afternoon, which is likely to continue until the beginning of the week and provide temporary relief.

The hornbeam has passed its flowering peak, but still causes low to moderate pollution. People who are sensitised to birch plants (e.g. birch, alder or hazel) may still experience cross-reactions.

The first oaks and beeches have already started to blossom in the Ländle. Due to their relationship to the birch family, they can also trigger cross-reactions.

Pollen from ash, willow and poplar are present in low to medium concentrations. The contamination can be higher, especially in the vicinity of larger stands.

Lilac is currently beginning to flower in Vorarlberg. As a relative of the ash tree, it can also trigger cross-reactions. However, as it is pollinated by insects, the amount of pollen is comparatively low and mainly relevant in the immediate vicinity. Anyone who is sensitive to olive trees should not place flowering branches indoors.

The plane treea popular park and avenue tree, is in bloom in Vorarlberg. Particularly along avenues of plane trees, this can sometimes lead to intensive exposure.

In warm, sunny locations, the first flowering panicle grasses. The resulting pollution is currently still localised.

In addition to the pollen types already mentioned maple oaks, larches, sour grasses, sessile grasses and cypress plants are also represented in the pollen spectrum. However, they only have a very low potential for allergic reactions.
