About Pollen in Doncaster

Doncaster’s primary spring allergens, Birch, Alder, and Oak pollen, dominate March-April from Sandall Beat Wood, Cusworth Hall parklands, and urban green spaces; April-May sees peak Ash and Sycamore; May-July brings intense Grass pollen from River Don/Dearne floodplains, Town Fields, and extensive local meadows.

Flat topography facilitates wide pollen dispersal, yet urban canyons and built-up zones locally concentrate airborne particles; September-November brings high Mould spore counts, exacerbated by damp conditions and decaying leaf litter in woodlands and along riverbanks.
