Birch pollen season at its peak - allergen load in Tyrol is gradually decreasing!

In the past week, pollen production and distribution in Tyrol have remained at a high level. We are still in the main phase of the pollen season, in which several tree species bloom at the same time.

Birch pollen: The birch pollen season has reached its peak and a downward trend is now being observed. This year the birch pollen season was particularly intense, with very high pollen concentrations over several consecutive days. Although the levels are now slowly decreasing, birch remains an important contributor to allergen exposure. The hornbeam is still present, but is also showing a downward trend. At the same time, the pollen concentrations of beech and oak are increasing. It is important to note that both can continue to trigger symptoms in people who are sensitised to birch pollen due to cross-reactions, even if birch pollen concentrations are already decreasing.

Ash pollen: Ash pollen is still present in the air and contributes to allergenic exposure. Moderate concentrations are predominantly measured in the region.

Sycamore pollen: The concentrations of plane tree pollen have been high in recent days, especially along avenues with corresponding tree populations. Concentrations are now expected to decrease.

Grass pollen: The first grass pollen are now being detected in the air. The grass pollen season is just beginning and could start early this year due to the current sunny and dry weather. We will continue to monitor developments closely and keep you up to date.

Other pollen types: There will also be pollen from larch, walnut, cypress plants and willow have been detected, but these have a low allergenic relevance.

Situation at higher altitudes: The allergenic load is gradually increasing at higher altitudes, with birch pollen concentrations already reaching moderate levels locally.

Even though birch pollen concentrations are slowly decreasing, the overall exposure to other pollen types and cross-reactions remains high. This phase therefore remains challenging for allergy sufferers, with grass pollen will become increasingly important in the coming weeks.
