POLLEN & SPORE REPORT

Important Notice 

The MAARA Executive committee decided at their last committee meeting, that MAARA would no longer fund the pollen and spore counting and reporting carried out by the University of Leicester.  MAARA’s pollen and spore archive will therefore no longer be updated after November this year and the reporting on this page will also cease. Please see the University of Leicester's new aerobiology twitter page where the reporting has moved to.

 

Pollen and fungal spore levels in the East Midlands

Prepared for MAARA by the University of Leicester's Aerobiology group New UoL logo Sept 2015 cropped

This page is dedicated to reporting the pollen and fungal spore levels in the East Midlands, paying particular mention to those known to be allergenic. This page will be updated regularly in the peak season (June/August) and as and when necessary outside these months.

The information provided is for the interest of, and use by, the general public only.

Recent pollen levels

All pollen

The pollen season is drawing to a close with grass pollen remaining at low levels over the last week.  The weed pollens of goosefoot and nettle were observed at low levels, as was the remaining tree pollen of yew.

Grass pollen

The grass pollen season is drawing to a close so levels are no longer monitored daily.  Daily counts will begin again in May 2023 and will hopefully be reported on the University of Leicester website.

 

Counts represent the average number of grass pollen grains per cubic metre of air for the period covering 9am on the date shown to 9am the following day. Counts are converted to a classification according to the table further down this page.

Recent fungal spore levels

Spore counts have been seen at low levels in the last 7 days. Both Cladosporium and Alternaria were below allergenic levels over the last week. 

 

Allergic individuals should take neccessary precautions.
