Local Environmental Conditions
Open grassland and woodland share the area around this part of Harris Township. In the immediate area, the woodland makes trees an important source; open grassland adds grass and weed pollen. Roadside verges and patches of open ground provide further room for grasses and weeds. Undergrowth, clearings and woodland edges add smaller amounts of grass and herb pollen.
Flowering trees bring the first pollen of the year in late spring. Grass pollen follows, peaking in early summer and easing off by late summer. A smaller weed peak follows from early summer into early fall. In warm, humid weather from early summer into early fall, mold spores add to the mix, especially after rain. By late fall, as temperatures fall to around freezing, pollen levels are low again.
