Local Environmental Conditions
The area around the center of Orrock Township is heavily wooded. The damp ground beside a stream or river nearby supports trees, shrubs and reeds, adding to local pollen. The leading allergenic tree nearby is oak, with hazel close behind. Beyond the trees, grasses matter a great deal, and mugwort and plantain are the main weed sources.
Hazel opens the pollen season in early spring. Tree pollen peaks in late spring, when the weather warms to around 15°C and oak is in full flower. Grass pollen follows, peaking in early summer and easing off by early fall. Mugwort and plantain bring a final peak from midsummer into early fall. Rain is heaviest in summer, often giving short breaks from high pollen levels.
