Allergenic Pollen Types

In the UK, sufferers of pollen allergies are most likely to be affected by tree pollens (birch, oak, hazel, plane and alder) and grass pollen.  All of these types are distributed through the UK. They are also spread across much of Europe, Asia, North USA and North Africa. The timing will differ from south to north and also west to east and with height above sea level. The exact timing and severity of the pollen seasons will differ from year to year depending on the weather and on biological factors.
