Local Environmental Conditions
The area around the center of Jamestown is a mix of built-up land and woodland. With Chautauqua Lake nearby, lakeside vegetation along its shore contributes to the local mix. In the immediate area, the surrounding woods make trees an important source; street trees, gardens and lawns supply most pollen in the built-up parts.
Flowering trees bring the first pollen of the year in mid-spring. Then come the grasses, strongest in early summer and fading by 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 5°C, pollen levels are low again.
