Mugwort pollen concentrations are rising across Tyrol – allergen levels are on the increase!

Mugwort (Artemisia) is now becoming the most significant allergenic pollen type of the late-summer pollen season in Tyrol. Pollen concentrations have risen across the entire region as more and more plants reach full bloom. In contrast, grass pollen concentrations have stabilised at a low level and are not expected to rise significantly further this season.

Mugwort pollen: Mugwort pollen concentrations have risen across the whole of Tyrol, and the allergen load is becoming increasingly noticeable. The flowering season is now in full swing, and mugwort is currently one of the most significant pollen types for people with allergies. Its pollen has a high allergenic potential and can trigger severe symptoms in sensitised individuals. Pollen levels can be particularly high near large stands of mugwort, which are frequently found on roadsides, along paths and field margins, as well as on fallow land and other disturbed sites. As the mugwort pollen season is now approaching its typical peak in mid-August, increased pollen levels are to be expected in the coming days.

Ragweed/Ambrosia: Ambrosia is another highly allergenic plant that becomes more prevalent during the late-summer pollen season. Several smaller hotspots are known to exist in Tyrol. In addition, a larger area has been identified between Rietz and Haiming where ragweed is spreading. To monitor pollen concentrations in this area closely, we have once again installed a pollen trap in Mötz this year. We are continuing to monitor developments closely and will keep you updated on any changes. People who are sensitive to ragweed and who live in or are visiting the Rietz–Haiming region should be particularly vigilant in the coming weeks.

Grass pollen: Grass pollen concentrations have now stabilised at a predominantly low level throughout Tyrol. The flowering season for most grasses is already well advanced or has finished, so no significant further increase is expected this season. Locally, slightly higher concentrations may still occur in the immediate vicinity of mountain meadows, pastures and other grass-rich areas. Plantain and sorrel pollen are also still present in the air in low concentrations and may cause additional symptoms in people with grass allergies.

Other pollen types: Pollen from the nettle family (Urticaceae) is currently very common in the air and is among the most frequently detected pollen types. Despite these high concentrations, nettle pollen is of only minor allergenic significance in Tyrol and is not considered a major cause of pollen allergies in the region.

Fungal spores: Concentrations of airborne fungal spores in Tyrol remain in the moderate to high range. Following periods of rain, concentrations may rise and trigger or exacerbate symptoms in sensitive individuals.

Weather, pollen levels and practical advice: Mugwort is currently the most important type of pollen that allergy sufferers should keep an eye on, whilst grass pollen levels remain predominantly low. Towards the end of the weekend and at the start of next week, more changeable weather is expected, which is likely to temporarily reduce pollen concentrations in the air and provide some relief. However, rainfall and increased humidity also encourage fungal growth and the release of spores, meaning that fungal spore concentrations may subsequently rise. People with mugwort allergies should be particularly cautious near large areas of flowering mugwort, whilst those with ragweed allergies should be especially vigilant in the area between Rietz and Haiming.
