Local Environmental Conditions
The area around the heart of Ames, Iowa is a mix of woodland and built-up land. With the Skunk River nearby, riverside trees such as poplar and plane tree along its banks contribute to the local mix. The leading allergenic tree nearby is oak, with maple and plane tree close behind. Grasses also feature strongly, alongside ragweed among the weeds.
Tree pollen peaks in late spring, when the weather warms to around 15°C and oak, maple and plane tree are in full flower. Then come the grasses, strongest in late spring and fading by early fall. The season closes with ragweed from late summer into mid-fall. Warm, damp weather from late spring into midsummer also raises mold spore levels.
