Local Environmental Conditions
Around 36% of the area near this part of Machesney Park is open grassland, with a good deal of woodland and farmland. With a watercourse close by, riverside trees such as willow and poplar contribute to the local mix. Allergenic trees nearby include oak, maple and poplar. Beyond the trees, grasses matter a great deal, and ragweed and plantain are the main weed sources.
Oak, maple and poplar lead the season in late spring, as temperatures climb to around 15°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. The season closes with ragweed and plantain from late summer into mid-fall. Summer is the wettest time of year, and heavy showers can bring short breaks in pollen.
