Local Environmental Conditions
The area around this site in West Branch Township is mostly woodland, with some open grassland. Around here, tree cover makes trees an important source; open grassland adds grass and weed pollen. Grasses along roadsides, verges and open ground also add to the overall pollen load. Gaps in the canopy, trails and forest edges give grasses and herbs room to grow.
Tree pollen comes first, peaking in mid-spring. Grasses take over in early summer, with temperatures around 20°C, and their pollen lingers into late summer. Weeds on open ground add a smaller late peak from early summer into early fall. By late fall, as temperatures fall to around freezing, pollen levels are low again.
