Local Environmental Conditions
A stretch of hazel and willow lines the water, feeding some of spring's earliest pollen, hardly 100 meters distant. Located not far off, about 450m out, this area has a canopy of oak and birch, birch chief among them for allergenic potency here. Nearby, right nearby, about 200m away, the park's turf and planted trees form a small but steady source of grass and ragweed pollen.
Water-edge hazel and willow are usually the first allergenic trees active here, usually peaking sometime between late winter and the end of March. Oak and birch in the woodland come next, through the heart of spring, usually hitting its highest point sometime between mid-April and mid-May. By late spring, grass pollen is climbing steadily toward a June high point, before ragweed pollen takes center stage across mid-August into October.

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