Local Environmental Conditions
This site in West Chicago Township is surrounded mainly by built-up land, which covers around 88% of the nearby area. The allergenic tree mix nearby includes maple, oak and poplar. Beyond the trees, grasses matter a great deal, and plantain and pigweed are the main weed sources. Compared with most places, ragweed is especially widespread here, which makes it one of the key local allergens.
Maple, oak and poplar lead the season in mid-spring, as temperatures climb to around 10°C, and tree pollen reaches its peak. Then come the grasses, strongest in early summer and fading by early fall. Plantain and pigweed bring a final peak from late spring into early fall. The ragweed period in early fall is usually the most intense time of year here.
