Here, just outside the immediate area, a stand of oak and birch, the latter ranked among the region's most potent tree allergens. Neighboring areas with similar land cover tend to show a closely matching pollen mix.
Hazel and willow near the water open the pollen calendar early, hitting its peak before most trees have even budded, around late winter into March. Oak and birch in the woods pick up where the earlier species leave off, peaking in the heart of spring, generally April into May. Grass pollen builds through late spring and peaks in June, before ragweed pollen takes center stage across mid-August into October.

The 0–100 scores represent risk levels, not direct measurements of pollen or air pollutant concentrations. Higher scores indicate higher risk. Pollen and air quality use different thresholds.
Pollen
| None | 0 | No or negligible risk of exposure. Pollen/mold exposure is expected to be minimal. |
| Low | 0-25 | Low risk of exposure. Small amounts of pollen or mold spores may be present. |
| Moderate | 25-50 | Moderate risk of exposure. Pollen/mold exposure is expected to be noticeable. |
| High | 50-75 | High risk of exposure. Elevated pollen/mold exposure is expected. |
| Very High | 75-100 | Very high risk of exposure. Pollen/mold exposure is expected to be at or near its highest levels. |
