About Pollen in Milton Keynes

Milton Keynes experiences peak spring tree pollen from March through May; Birch pollen is prolific across numerous linear parks and residential avenues; Oak follows, dominant in woodlands such as Howe Park Wood and Loughton Valley Park; late May to July sees high Grass pollen levels originating from extensive local floodplains, Ouzel Valley Park meadows, and roadside verges.

The city’s dense urban green infrastructure and grid road network contribute to localised pollen trapping and recirculation; autumn and winter introduce elevated mould spore counts, particularly from damp decaying organic matter in woodlands and along the Grand Union Canal.
