Local Environmental Conditions
Woodland and farmland share the area around Starved Rock Campground. The damp ground beside running water nearby supports trees such as poplar, adding to local pollen. Oak is the most prominent allergenic tree nearby, with juniper and maple also present. Grass pollen is plentiful, while ragweed leads among the weeds.
Oak, juniper and maple lead the season in late spring, as temperatures climb to around 15°C, and tree pollen reaches its peak. Then come the grasses, strongest in late spring and fading by early fall. Ragweed brings a final peak from late summer into mid-fall. Summer is the wettest time of year, and heavy showers can bring short breaks in pollen.

This allows us to estimate pollen levels for today and the coming days, not just report the past.
