Local Environmental Conditions
Around 47% of the area near this part of South Chicago Township is built-up land, with a good deal of open water and some open grassland. The damp ground beside a watercourse nearby supports trees such as poplar, adding to local pollen. Allergenic trees nearby include maple, oak and elm. Grass pollen is significant here, and ragweed and plantain contribute weed pollen.
The pollen year starts in early spring, when elm flowers. Maple and oak follow in mid-spring, as temperatures climb to around 10°C, and tree pollen reaches its peak. Grasses take over in early summer, with temperatures around 20°C, and their pollen lingers into early fall. Ragweed and plantain bring a final peak from late summer into mid-fall.
