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.

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

Grass pollen remained at low levels over the weekend.  The weed pollens of mugwort, plantain, dock and goosefoot were observed at low levels, while nettle pollen reached very high levels over the weekend.  The tree pollen season is drawing to an end with the remaining pollens of lime and yew being observed at low levels. 


Allergic individuals should continue to take neccessary precautions.

Recent fungal spore levels

Spore counts have been seen at moderate levels in the last 7 days. Both Cladosporium and Alternaria remained above allergenic levels over the last week, this is likely to continue if the weather continues to be warm and dry.


Allergic individuals should take neccessary precautions.
