Located close to this spot, this area has oak and birch make up the bulk of this woodland, birch being the more potent allergen of the two. Local readings for the surrounding area tend to follow this same general pattern.
The water-adjacent hazel and willow are early risers, getting an early start, typically cresting between February and March. Oak and birch in the nearby woodland follow in mid-to-late spring, usually peaking from April into May.

Pollen can travel long distances, but this usually matters only early in the season or during specific wind events.
Are pollen levels in Fairview Heights 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 Fairview Heights, 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. |
