Local Environmental Conditions
Here, close by, the water's edge is thick with hazel and willow, whose pollen spreads readily in early spring. Here, within easy reach, woodland dominated by oak and birch, with birch a leading regional tree-pollen allergen. Here, just around the area, grass and ornamental trees within the park boundary contribute modestly to grass and ragweed levels.
Hazel and willow by the water are typically first out of the gate, peaking in late winter through March. Oak and birch in the woodland come next, through the heart of spring, building to its sharpest point across April and May. Grass pollen climbs toward a June peak, then yields to ragweed, the dominant late-summer and fall allergen through October.

Pollen can travel long distances, but this usually matters only early in the season or during specific wind events.
Are pollen levels in Cherry Valley Township based on measurements or forecasts?
Pollen data is often misunderstood. Most "pollen levels" are not real-time measurements, but forecasts.
Direct pollen measurements are typically delayed by 1-2 days because they require manual analysis. To show current conditions in Cherry Valley Township, modern forecasts combine recent measurements, weather data, and information about local vegetation.
This allows us to estimate pollen levels for today and the coming days, not just report the past.

Understanding the Scale
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. |
