Local Environmental Conditions
Open water and woodland share the area around this site in Town of Southold. The damp ground beside running water nearby supports trees, shrubs and reeds, adding to local pollen. Common allergenic trees nearby include maple. Grasses are a major source, with mugwort adding to the weed pollen load. Undergrowth, clearings and woodland edges add smaller amounts of grass and herb pollen.
Tree pollen peaks in mid-spring, when the weather warms to around 10°C and maple is in full flower. Grasses take over in early summer and keep pollen in the air into early fall. Mugwort brings a final peak from midsummer into early fall. Mold spores join in from early summer into early fall, when damp, warm spells let them thrive.
