Local Environmental Conditions
Nearby, roughly 400m away, along the damp banks, hazel and willow release some of the year's first tree pollen. Grass and ornamental trees within the park boundary contribute modestly to grass and ragweed levels; this sits within 100-200m of this spot. As with most local readings, actual levels can vary somewhat with short-term weather swings.
Hazel and willow near the water open the pollen calendar early, building through the tail end of winter into March. Through late spring, grass pollen climbs steadily toward its June peak, before ragweed becomes the more dominant allergen from mid-August into October. Actual peak timing can drift earlier or later depending on how the season's weather plays out.

Are pollen levels in Plainfield 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 Plainfield 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. |
